Giving Daily Predictions Of Time Of Low And High Waters. Part 2: Data Of Secondary Ports. Part 3: Principle Of Harmonic Constants. Important Definitions: 1) 1) Bore Tide: As A Progressive Wave Enters Shallow Waters Its Speed Decreases. Since The Trough Is Shallower Than The Crest Retardation Is Greater Resulting In The Steepening Of Wave Front So In Estuaries Advance Of Trough Is So-Much Retarded That The Crest Of The Rising Tide Overtakes It And Advances Upstream In A Churning Wall Of Water.. Dangerous For Moored Ships Which Can Surge. 2) 2) Chart Datum: Lowest Astronomical Tide Below Which The Level Of Water Doesn’t Usually Fall. 3) 3) Negative Surges: Fall In Low Water Or Predicted Water Due To Meteorological Reasons. 4) 4) Seiches: Occurs In A Confined Body Of Water. A Long Wave Having Crest At One End And Trough At Other End Of Confined Space.Abrupt Changes In Meteorological Conditions Like Passage Of An Intense Depression Or Line Of Squall May Cause Oscillations Of Sea Level, So The P0eriod Between Successive Waves Can Be Unpredictable, Few Minutes To Two Hours.

Harmful Aquatic Organisms In Ballast Water An Mepc Working Group On Ballast Water Reported Progress In Developing Draft New Regulations For Ballast Water Management. It Is Intended To Include These In A New Annex To Marpol, To Be Adopted At A Conference Provisionally Scheduled For 2000. Implementation Guidelines For The Proposed Annex Are Also Being Developed, Which Are Expected To Be Included In A Code Related To The New Annex. The Proposed New Annex Vii Is Aimed At Addressing The Environmental Damage Caused By The Introduction Of Unwanted Aquatic Organisms In Ballast Water, Used To Stabilize Vessels At Sea. Globally, It Is Estimated That About 10 Billion Tonnes Of Ballast Water Is Transferred Each Year. The Water Taken On Board For Ballasting A Vessel May Contain Aquatic Organisms, Including Dormant Stages Of Microscopic Toxic Aquatic Plants - Such As Dinoflagellates, Which May Cause Harmful Algal Blooms After Their Release. In Addition, Pathogens Such As The Bacterium Vibrio Cholerae (Cholera) , Have Been Transported With Ballast Water. As Ships Travel Faster And Faster, The Survival Rates Of Species Carried In Ballast Tanks Have Increased. As A Result, Many Introductions Of Non-Indigenous Organisms In New Locations Have Occurred, Often With Disastrous
Consequences For The Local Ecosystem - Which May Include Important Fish Stocks Or Rare Species. The Mepc Approved A Questionnaire To Be Sent To Member States To Obtain Information On Current Domestic Laws And Regulations On Ballast Water Management. It Is Intended That The New Internationally Binding Regulations Would Avoid A Situation Whereby Individual Governments Adopted Their Own Rules To Prevent Contaminated Ballast Water Affecting Their Local Ecosystems. Meanwhile, The Mepc Noted The Different Options For Introducing The Proposed Regulations. The New Annex To Marpol, As Originally Proposed, Could Be Adopted Via A Protocol To Add A New Annex To Marpol 73/78, Or It Could Be Adopted As A New Annex Via Amendments To Marpol 73/78, A Simpler Process. Another Option Is For A Diplomatic Conference To Adopt A New Convention On Ballast Water Management, Under Which The Terms For Entry Into Force Would Be Determined By The Conference, Instead Of Having To Comply With Existing Entry Into Force Terms Established By Marpol 73/78. The Mepc Agreed To Consider A Legal Framework For The New Regulations At Its Next Session In November.

Marine Environment Protection Committee 40th Session 18-25 September 1997 Committee Tackles Ballast Water Problem The Committee Discussed Measures To Deal With The Problem Of Harmful Aquatic Organisms Transported In Ballast Water And Approved A Draft Assembly Resolution On Guidelines For The Control And Management Of Ship’s Ballast Water To Minimize The Transfer Of Harmful Aquatic Organisms And Pathogens, For Submission To The 20th Assembly For Adoption. There Has Been Increased Awareness In Recent Years Of The Environmental Damage Caused By The Introduction Of Unwanted Aquatic Organisms In Ballast Water, Used To Stabilize Vessels At Sea. Examples Of Introductions Of Non-Indigenous Organisms In New Locations Include The Introduction Of The European Zebra Mussel (Dreissena Polymorpha) In The North American Great Lakes, Resulting In Expenses Of Billions Of Dollars For Pollution Control And Cleaning Of Fouled Underwater Structures And Waterpipes; And The Introduction Of The American Comb Jelly (Mnemiopsis Leidyi) To The Black And Azov Seas, Causing The Near Extinction Of The Anchovy And Sprat Fisheries.
Human Health Has Also Been Badly Affected, With The Transportation Of The Bacterium Vibrio Cholerae (Cholera) To Latin American Coastal Water, Probably Through Discharges Of Ballast Water From Asia, And The Introduction Of The SouthEast Asian Dinoflagellates Of The Genera Gymnodinium And Alexandrium, Which Cause Paralytic Shellfish Poisoning, To Australian Waters. The Draft Guidelines, Which Have Been Drawn Up By A Working Group On Ballast Water, Are Aimed At Minimizing The Risks Of Introducing Harmful Aquatic Organisms And Pathogens While Maintaining Ship Safety. Some States Have Already Introduced Mandatory Management Of Ballast Water To Prevent The Introduction Of Exotic Species. Guidelines For Preventing The Introduction Of Unwanted Organisms And Pathogens From Ships’ Ballast Waters And Sediment Discharges Were Adopted By The Committee In 1991 And Subsequently As An Assembly Resolution A.774(18), But The Revised Version Incorporates Further Recommendations On Tackling The Problem, Including How To Lessen The Chances Of Taking On Board Harmful Organisms Along With Ballast Water. The Recommendations Include Informing Local Agents And/Or Ships Of Areas And Situations Where Uptake Of Ballast Water Should Be Minimized, Such As Areas With Known Populations Of Harmful Pathogens Or Areas Near To Sewage Outlets. Ships Should Operate Precautionary Practices, Through Avoiding Loading Ballast Water In Very Shallow Water Or In Areas Where Propellers May Stir Up Sediment. Unnecessary Discharge Of Ballast Water Should Also Be Avoided. Procedures For Dealing With Ballast Water Include Exchange Of Ballast Water At Sea And Discharge To Reception Facilities, While The Guidelines Note That In The Future Treatment Using Heat Or Ultraviolet Light Could Become Acceptable To Port States. Imo’s Maritime Safety Committee (Msc) And The Committee Have Already Approved Guidance On Safety Aspects Relating To The Exchange Of Ballast Water At Sea, Which Outlines Procedures For Exchanging Ballast Water And Point Out Safety Issues Which Need To Be Considered, Such As Avoidance Of Over And Under Pressurization Of Ballast Tanks And The Need To Be Aware Of Weather Conditions. The Committee Approved A Programme Of Work For The Ballast Water Working Group, Which Includes Developing Draft Regulations On Ballast Water Management To Be Adopted As An Annex To Marpol At A Conference Of Parties To The International Convention For The Prevention Of Pollution From Ships, 1973, As Modified By The
Protocol Of 1978 (Marpol 73/78), The Main International Convention Dealing With The Prevention Of Pollution From Ships. The Conference Is Scheduled To Be Held In The Year 2000.

Bridge Equipment-G.P.S.
Space Segment: • • Satellites Are To Be Operated In 6 Orbital Planes In Very High Orbits, Approximately 20,200 Kms Above The Earths Surface. • • Four Satellites Are Located In Each Plane Having One Spare In Every Alternate Orbit. The Configuration Being 21+3 Satellites. The Orbital Planes Are Inclined At 55 Degs To The Equator. • • The Orbital Period Of These Satellites Is Just Under 718 Minutes Resulting In The Satellites Passing Over The Same Ground Point Each Day, Excepting The Fact That They Are Four Minutes Earlier (Give Or Take 1.7 Secs). • • The Orbit Design Was Developed To Guarantee That Atleast Four Satelites Are Alkways In View At Every Point On The Earths Surface 24 Hours A Day. Ground Segment: • • The Ground Or Control Segment Refers To The Ground Based Element Of A Gps System Which Manages The Performance Of The Satellites • • This Is Through Orbital Tracking, Clock Monitoring And Therefore Fundamentally Is Responsible For The Daily Control Of The System. • • The Control Segment Of The Navstar System Consists Of Three Main Types Of Operational Facilities. • • The Master Control Station Situated At Colorado Springs Is Responsible For Overall Satellite Control, Navigation Performance Estimation And Ephemeris Production. • • Four Further Sites At Hawaii, Ascension Islands, Diego Garcia And Kwajalein Alongside The Master Are Operated As Monitor Stations For Tracking The Satellites And Collecting Range Data To Produce Information For Ephemeris (Orbit) Modelling.
• •
• Uplink Antennas To Transmit Navigation Data And Commands To The Satellites Have Also Be Hoisted From Such Stations. • The Uplink Frequency Is Centered On 1783.74 Mhz, With Downlink Frequency Of 2227.5 Mhz.
User Segment: • • The User Segment Mainly Consists Of The Gps Antenna And Receiver, Additional Features However Would Include A Differential Gps Antenna And Various Interfaces Into Systems. • • From Noise To Signal: The First Task For The Gps Receiver Is To Get Enough Signals From The Satellite Transmissions Into The Receiver Itself. • • It Is Usually Achieved With A Pre-Amplifier/Head Amplifier In The Antenna Unit To Boost The Signal Before Sending It Down The Cable. • • Antennas Are Designad To Receive All Signals Within The Relevant Band.The Gps Signals Are Very Weak And Indistinguishable From The Background Noise At First And Second Glance. • • These Signals Are Also Spread Over A 20 Mhz Band-Width Centered Around The L1 Frequency Of 1575.42 Mhz. This Has The Same Effect As Transmitting A Much More Powerful Signal And Also Allows Much More Information To Be Incorporated Into The Transmissions. • • From Signal To Numbers: Most Signal Processing Tasks Are Now Undertaken In Micro-Processors, But To Allow This The Signal Must Be Converted From Analogue To Digital Form. • • From Numbers To Code: The Gps Receiver Will Now Have At This Point The Ability To Sample The Substantially Altered Frequency Of The Satellites. The Primary Task Of The Receivers Is To Measure Ranges To The Satellites.This Is Achieved By Attempting To Identify The Code Transmissions Superimposed On To The Signals. • • Each Satellite Transmits A Unique Code, Or Technique Known As Code Division Multiple Access. To Identify The Code The Receiver Has To Produce An Exact Replica Of The Satellite Code Sequence And To Mach The Two Together. • • From Numbers To Phase: To Make Use Of This Code Information To Produce Ranges And Thus Position The Receiver, Also Needs Another Set Of Information, The Satellite Ephemeris. • • The Ephemeris Being Modulated Over The Carrier Frequency And Needs Also To Be Extracted. • • From Measurement To Position: Once The Receiver Has Produced The Necessary Information In Terms Of Measured Pseudo Range And Navigation Data, This Is Then Poassed To A Dedicated Microprocessor Dealing With The Position Computation And, Usually, The User Interface As Well. The Pseudo- Range:
The Pseudo- Range Is A Measure Of Distance From The Receiver To The Satellite, Usually Expressed In Mts. The Term Pseudo Is Used Because The Range Is Contaminated. For Time To Be Accurately Measured Between The Two Sites The Clocks Must Be Accurately Synchronised. The Clocks Between The Satellites Are Synchronised, So The Ranges Measured Between Them Would Actuallyu Be True Ranges. But The Receiver Clock Is Not Synchronised To The Satellites Which Gives An Error Which Can Be Resolved Mathematically, Hence The Term Pseudo-Range. The Pseudo-Range Cannot Be Converted To A True Range Without Other Sets Of Information, Namely Ranges To Three Other Satellites And Accurate Knowledge Of All The Satellites Positions In Space ( And Time ) Computation Of Position:
The Ability To Measure Pseudo Range And Knowledge Of The Satellites Position At All Times, The Gps Receiver Now Has Enough Information To Calculate A Position. For Every Computation Of Position There Are, Then Four Unknowns Called X,Y,Z And T (For Time). But By This Point The Receiver Has Also Managed To Acquire A Whole Series Of Knowns Namely, Pseudo Ranges To The Satellites And The Position Of Those Satellites. As Long As The Receiver Can Measure As Many Ranges To The Satellites As There Are Unknowns Then Position Can Be Calculated Quite Simply Through A Series Of Four Simultaneous Equations. This Is A Mathematical Technique That Uses A Combination Of Known Quantities To Calculate A Combination Of Unknown Quantities, But It Does Require Symmetry In Its Equation Forms- Basically The Same Number Or More Knowns To Unknowns. The Dilution Of Precision:
This Is One Of The Primary Quality Control Indicators Available To The User Of The Gps Receiver. It Indicates The Geometrical Relationship Of The Satellites. The Dilution Of Precision Was The Mechanism Userd By The Gps System Planners To Identify The Best Orbit Geometry Of The Satellites To Provide The Best User Geometries. On Its Own The Dop Figure Is Only A Qualitative Figure With The Prescribed Numbers Not Being Of Any Specific Units. The Most Complete Dop Is The Geometric Dilution Of Precision (Gdop). This Is The Factor Used To Design The Orbital Arrangement Of The Satellites. Gdop Brings Together The Four Unknowns Of The System. The Most Frequently Used Dop’s Are Pdop ( Position Dilution Of Precision) And Hdop ( Horizontal Dilution Of Precision). Pdop Is Used By Those Interested In Three Dimentional Positioning (Lat/Long/Ht). Hdop Is For Two- Dimensional Positioning. For Most Purposes Hdop Is Used By The Marine Community. Dop Figures Are Actually Used By A Navigator In The Following Way. If A Composite Pseudo-Range Measurement Error Of 10 Mts. (95% Probability) Is Assumed For The System, Then By Multiplying This Figure By The Relevent Dop Value, Eg. 3.0, Gives An Overall Position Accuracy Of 30 Mts. Dop Figures Are Therefore Only Relative Numbers, With Smaller Dop’s Giving Better Accuracies.
The Final Constellation Is Designed To Guarantee Pdop Figures Of Better Than 12.0 All Over The Earth’s Surface, Though Figures Of Better Than 7.0 Are To Be Generally Expected. For Marine Applications Hdop Figures Are More Useful & The Design Figure Of 3.0 Is To Be Expected For The Majority Of Coverage.
Errors Of The System.
1) 1) Gdop - If The Configuration Of The Available Satellites Is Not Suitable, Accuracy Of The Fix Is Affected. 2) 2) Ionospheric & Tropospheric Delays Of Signals - While Ultra High Frequencies Are Used For Transmission, Yet The Ionosphere & Troposphere Refract The Signals Causing Delays Which Lead To Inaccuracy Of Positions. These Errors Can Be Reasonably Predicted & Are Fed Into A Mathematical Model Built Into The Software Of The Receiver. 3) 3) Satellite Clock Error - Any Errors In The Clocks On Board The Satellites Will Lead To Errors In Time Measurement. 4) 4) User Clock Error - Same As Above. This Is Eliminated By Using An Extra Satellite Equation 5) 5) Deviation Of Satellites From Their Predicted Orbits - Since The Position Of The Satellites Needs To Be Known Very Accurately, It Is Obvious That If The Satellite Deviates From Its Orbit, For Any Reason, Then Inaccuracy In Fixes Will Result. 6) 6) Receiver Errors - These Are Small & Are Caused Due To Internal Noise, Computational Errors, Etc.
The Dilution Of Precision. Gdop Pdop Hdop Edop Ndop Tdop
Geometric Dilution Of Precision Integrates X,Y,Z, And Time. Position Dilution Of Precision Integrates X,Y,Z, Three Dimentional Positions. Horizontal Dilution Of Precision. Two Dimentional Marine Positioning. Easting Dilution Of Precision Northing Dilution Of Precision, X And Y Positioning Seperated. Time Dilution Of Precision For Time Transfer Users.
The Satellite Geometry Is Presented To The User By A Factor Known As The Dilution Of Precision. These Figures Are Used To Assess The Potential Positioning Quality Of A Certain Satellite Constellation And To Help Provide Realistic Quality Control Information. The Procedure Used To Define These Values Is Quite Complicated, But It Relates The Difference In Three Dimentions Of The User To All The Concidered Satellites In A Geometrical Sense. The Resultant Dop Figure Then Suggests The Amplification Of Pseudo-Range Measurement Error Into User Positioning Error. Differen Dop’s Are Used Depending On The Type Of Position Calculated. Hdop For A Two Dimentional Fix And Pdop For A Three Dimentional Fix. The Dop Figures Are Used By The Navigator In The Following Way. If A Composite Pseudo-Range Measurement Error Of 10 Metres (95% Probablity) Is Assumed For The System, Then Multiplying This Figure By The Relevant Dop Value, Eg. 3.0, Gives An Overall Positioning Accuracy Of Thirty Metres. Dop Figures Are Therefore Only Relative Numbers, With Smaller Dop’s Giving Better Accuracy. The Probablity Figures Detailed In The Circular Brackets Are Indications Of The Confidence In The Position Accuracy. Bridge Equipment - Logs Electromagnetic Log: In A Magnetic Field Created By A Solenoid, The Magnetic Flux Lines Extend Out In The Water. Salt Water Being A Conductor Flowing Past The Solenoid Creates An Emf. This Is Picked Up By A Sensor & A Pre-Calibrated Voltmetre. The Voltage Induced Is Proportional To The Speed Of The Water. Doppler Effect: The Doppler Frequency Shift Is The Difference Between The Received Frequency Which Can Be Measured & The Transmitted Frequency Which Is Known. • • There Are 2 Types Of Logs; 1. 1. Continuous Wave (Cw) & 2. 2. Pulse Type. The Pulse Type Is Better Than The Cw. Type Because There Is A Signal Leakage From The Transmitter To The Reeciver Which Interferes With The Received Signal (Feedback). • • It Uses A Higher Frequency Than The Echo Sounder As The Smaller Wavelength Makes A Concentrated Beam Possible Hence, Less Loss Of Energy To Water, Stronger Echoes & Smaller Area Of Transducer Required. Also Diffused Reflection Is Acquired By The High Frequency Which Is Neccesary Because Of Oblique Incidence Of The Transmitted Pulse.

6. Bulk-carrier safety solas chapter-12
home. Chpt 12 Solas….Safety Measures For Bulk Carriers Came Into Force On 1st July 99
All New Bulk Carriers 150 Mts. Or More In Length Built After 1st July 1999 Eg. Wheat, Rice And Timber Carrying Cargoes With A Density Of 1000 Kg/Mt^3 And Above Should Have Sufficient Strength To Withstand Flooding Of Any One Cargo Hold Taking Into Effect Dynamic Effects Resulting From Presence Of Water In The Hold And Taking Into Account The Recommendations Adopted By I.M.O. For Existing Bulk Carriers Built Before 1st July 1999 Carrying Bulk Cargoes With A Density Of 1780 Kg/Mt^3 And Above The Transverse Water Tight Bulkhead Between The Two Foremost Cargo Holds And The Double Bottom Of The Foremost Cargo Hold Should Have Sufficient Strength To Withstand Flooding And Related Dynamic Effects In The Foremost Cargo Hold. If Not So The Surveyors Can Place Restrictions On The Cargo Carried And Such Bulk Carriers Should Be Permanently Marked With A Solid Triangle On Its Side Shell And Will Not Be Permitted To Carry Any High Density Cargoes. The Triangle Being Equilateral And The Apex Of It Being 300 Mm Below The Deck Line Both Obn The Port And Stbd Sides. The Length Of Each Of Its Sides Should Be 500 Mm. Major Loss Of Bulk Carriers At Sea: If The Ship Is Flooded In The Forward Hold For Reasons Like Collision Etc. The Bulkhead Between The Two Foremost Holds May Not
Be Able To Withstand The Pressure That Results From The Sloshing Mixture Of Cargo Water And Assorted Debris, Especially If The Ship Is Loaded In Alternate Holds With High Density Cargoes. If The Bulkhead Between One Hold And The Next Collapses,Progressive Flooding Would Rapidly Occur Throughout The Length Of The Vessel Causing Her To Founder Within Minutes. This Being The Major Cause Of The Loss Of Bulk- Carriers At Sea. Maritime Safety Committee - 70th Session: 7-11 December 1998 Further to the note above; Maritime Safety Committee To Further Review Bulk Carrier Safety The Maritime Safety Committee (Msc) Considered Further Measures To Enhance The Safety Of Bulk Carriers. In November 1997, Imo Adopted A New Chapter Xii On Bulk Carrier Safety To The International Convention For The Safety Of Life At Sea (Solas), 1974. Chapter Xii Aims To Prevent Losses Of Bulk Carriers Due To Structural Failure Following Flooding Of The Foremost Hold, Identified As The Cause Of A Number Of Losses Of Bulk Carriers In The Early 1990s. The Chapter Contains A Number Of Requirements For Improving The Structural Integrity Of Bulk Carriers, Including Strengthening The Double Bottom And Bulkhead Of The Foremost Hold Where Required. However, A 1998 Report On The Sinking Of The Bulk Carrier Derbyshire In September 1980 With The Loss Of 44 Lives, Presented At The Last Session Of The Msc In May By The United Kingdom, Contains Further Recommendations Relating To The Design And Construction Of Bulk Carriers. Based On The Report Of A Working Group On Bulk Carrier Safety, Which Reviewed The Findings Of The Report, The Msc Agreed To Refer A Number Of Issues To The Sub-Committee On Stability And Load Lines And On Fishing Vessel Safety (Slf), Including: 1. 1. Strength Of Hatch Covers And Coamings; 2. 2. Freeboard And Bow Height; 3. 3. Reserve Buoyancy At Fore End, Including Forecastles; 4. 4. Structural Means To Reduce Loads On Hatch Covers And Forward Structure; And 5. 5. Fore Deck And Fore End Access. These Issues Will Be Considered In The Context Of The Ongoing Review Of The 1966 Load Lines Convention. The Msc Invited Delegations To Submit Proposals On Other Specific Issues, Including Dealing With Loss Of Steering Ability On A Bulk Carrier And Training And Operational Matters The Msc Also Invited Further Submissions On Proposals That New Bulk Carriers Should Be Required To Carry A Safe Haven, Which Would Float Free If The Ship Were To Sink, And That Existing Bulk Carriers Should Be Fitted With Freefall Lifeboats. The Msc Agreed Various Interpretations And Clarifications Requested By The 1997 Solas Conference And Adopted Them By An Msc Resolution. These Include The Identification Of Bulk Carriers For Port State Control Purposes, The Definition Of Bulk Carrier In Solas Chapter Ix And The Application Of Solas Regulations Xii/9 On
Requirements For Bulk Carriers Not Being Capable Of Complying With Regulation 4.2 Due To The Design Configuration Of Their Cargo Holds And Xii/10 On Solid Bulk Cargo Density Declaration. Formal Safety Assessment Study On Bulk Carriers Agreed The Msc Agreed With A United Kingdom Proposal To Carry Out A Formal Safety Assessment (Fsa) Study Of Bulk Carriers, To Aid Future Imo Decision-Making On Bulk Carrier Safety. Fsa Is Described As A Rational And Systematic Process For Assessing The Risks Associated With Any Sphere Of Activity, And For Evaluating The Costs And Benefits Of Different Options For Reducing Those Risks. It Therefore Enables, In Its Potential Application To The Rule Making Process, An Objective Assessment To Be Made Of The Need For, And Content Of, Safety Regulations. The Fsa Study, Scheduled To Be Completed Over A Two Year Period By A Number Of Imo Member States In Collaboration With Observer Organizations Will Look At A Range Of Measures To Improve Bulk Carrier Safety, Including Problem Areas Referred To The Msc By The Solas Conference Of November 1997, Which Adopted The New Chapter Xii To Solas On Bulk Carrier Safety. The Fsa Study Is Also Likely To Consider Further Whether Chapter Xii Should Apply To Bulk Carriers Under 150 Metres In Length And To Double Skin Bulk Carriers, As Well As Those Of Single Skin Construction. The Study May Also Look At The Benefits Of Specific Safety Measures, Such As The Need For A Device To Detect Water Ingress Into Cargo Holds Of Existing Bulk Carriers Would Assist In Warning The Crew Of Situations Where One Or More Holds Were In The Process Of Flooding And The Possible Need For Crew Access To The Foredeck In Heavy Weather. Fsa Consists Of Five Steps: • • Identification Of Hazards (A List Of All Relevant Accident Scenarios With potential Causes And Outcomes); • • Assessment Of Risks (Evaluation Of Risk Factors); • • Risk Control Options (Devising Regulatory Measures To Control And Reduce The Identified Risks); • • Cost Benefit Assessment (Determining Cost Effectiveness Of Each Risk Control Option); And • • Recommendations For Decision-Making (Information About The Hazards, Their Associated Risks And The Cost Effectiveness Of Alternative Risk Control Options Is Provided).

8. Care Of Ropes home. 1) 1) Examine The Ropes For Chafing, Cutting And Internal Wear. 2) 2) Keep Away From Direct Sunlight, They Should Be Stored Underdeck For Long Voyages But If Kept Outside They Should Be Kept Covered With Tarpolines Or On Gratings. 3) 3) Ropes Should Never Be Stowed Away Wet To Prevent Rotting. 4) 4) They Should Be Free From Grease Oilstains And Paint Marks Etc. 5) 5) They Should Never Be Surged To Prevent Wear And Tare Due To Friction, Some Ropes Have A Low Melting Point And Can Permanently Fuse And Get Damaged. 6) 6) Wire Ropes Should Be Regularly Lubricated With Patent Lubricants Such As Surret Fluid Or Wire Grease. 7) 7) For A Wire Rope Care Should Be Taken While Breaking A New Coil As The Rope May Get Kinked Or A Person May Get Injured Due To Faulty Handling. Break The Coil As Per Instructions Given In The Seamanship Manuals Eg.The Vertical Swivel Or The Reel. Always Use Gloves Whenever The Handling Of Ropes Is Concerned. 8) 8) Sharp Angles (Nips) To The Wire Rope Need To Be Avoided.
9) 9) Rollers Need To Be Used When Wires Are Being Used As Unnecessary Chafing Occurs. 10) 10) When Turned On Bits The Top Turns Should Be Secured Against Springing Off By A Light Lashing.
Handling, Maintainence And Inspection: • • Synthetic Lines Can Pose A Great Danger To Personnel If Not Properly Used Or Handled. Handling Of Mooring Lines Has A Higher Potential Accident Risk Than Most Other Shipboard Activities. • • The Most Serious Danger Is Snap-Back, The Suddern Release Of Static Energy Stored In The Stretched Synthetic Rope When It Breaks. • • Snap-Back Is Common To All Lines And Even Long Wire Lines Under Tension Can Stretch Enough To Snap-Back With Conciderable Energy. • • Synthetic Lines Break Without Warning And There Are No Visible External Signs Regarding This Danger. • • As A General Rule Any Point Within About A 10 Degree Cone Around The Line From Any Point At Which The Line May Break Is In Danger. A Broken Ine Will Snap Back Beyond The Point At Which It Is Secured, Possibly To A Distance As Far As Its Own Length.

5.1 General
• To Ensure The Efficient Fulfilment Of The Voyage It Is Essential That There Should Be In Good Communications Between Master And Charterers/Company. •
Communications May Be Divided In Two Broad Groups:
A) Immediate : Those Affecting Current Operations And Being For Informations Or Action Upon Receipt B) Historic : Those Reporting On Past Operations, Ships’ Performance, Incidents Of Interest Etc. The First Group Are Normally Channelled Via Cable, Radio Or Telephone, Whilst The Latter Concern Letters, Reports, Printed Forms, Etc. This Chapter Describes Communications In The “Immediate” Category. The Second Group Of Communications Are Dealt With At Appropriate Charterers’/Owners’ Requirements. 5.2 Voyage Instructions • Details Of The Cargo To Be Loaded And Voyage To Be Performed, Together With Bunkering Instructions And, Where Necessary, Fresh Water Instructions, Are Passed To The Ship’s Master Through The Agent At The Unloading Port Or Directly Via Radio/Fax/Tlx. • • • • • • •
The Instructions Will Contains Following Standard Information • • • • • •
Loading And Discharging Ports Approx. Volume At 15 Degree Centigrade Limiting Drafts At Loading/Discharging Port If Any Special Requirements (I.E. Cargo Heating) Special Properties Of Cargo (I.E. H2s) Stemming Details
In Addition To These Instructions The Following Messages In Connection With The Next Loading Are Passed To Ship Direct By Radio/Fax/Tlx Or Through Agents: (A)
White/Clean Oil Tankers The Intended Cargo, Voyage And Bunkering Instructions Are Sent To The Ship As Long As Possible In Advance Of Her Arrival At The Loading Port. This Is Done To Enable The Master To Confirm The Required Segregation And To Plan His Cargo Stowage, Also To Decide What, If Any, Further Tank Cleaning Is Necessary Prior To Arrival (Refer Marpol 73/78 With Latest Amendments And Ics/Isgott Chapter 8 Last Edition).
(B)
Black/Crude Oil Tankers Every Effort Is Made To Give Masters An Indication At The Previous Discharge Port Of Their Next Cargo And Voyage, To Enable Them To Decide On What Tank
Cleaning Is Required At Sea, To Prepare Tentative Cargo Stowage Etc. (Ref. Must Be Done To Marpol 73/78 Latest Edition With Latest Amendments An To Ics/Isgott Chapter 8 Last Edition). 5.3 Notice Of Readiness At Arrival At Customary Anchorage Or At Waiting Place At Loading/ Discharging Port, The Vessel Will Tender Notice Of Readiness (N.O.R.) 6.

• • • • •
Trim Segregation Best Loading/Discharge Sequence Cargo Quality Security Limiting Zone Of The Loaded Passage
When Handling Multi-Grade Cargoes Every Effort Must Be Made To Stow Them With Due Regard To Segregation And Trim, And In Such A Way That, Whenever Shore Facilities Allow, Two Or More Grades Can Be Handled At The Same Time During The Greater Portion Of The Loading/Discharge Period. Concerning The Cargoes It Is Necessary To Clarify Masters’ Responsibility With Regard To Inspection Of Tanks And Suitability To Load Particular Grades, And Owner Wishes To Emphasise, That In The Final Analysis, The Responsibility For The Condition Of The Ship, The Care Of Cargo And Liability For Contamination Of A Particular Grade Lies With The Master Alone. It Is, Therefore, The Master Who Must Finally Decide What Degree Of Cleaning Is Necessary, And He May Of Course, Seek Advice From Installation Representatives Whenever He Considers It Advisable To Do So. 6.3 Cargo Equipment • Before Loading/Unloading Operation The Cargo Officer Shall Assure Himself That As Per Visual Assessment And Pre-Testing (Where Possible) Of Cargo Tanks, Ballast Tanks, Cargo Lines, Ballast Lines, Cargo And Ballast
Pumps, Igs System And All Instruments That Must Be Used For Incoming Operations Are In All Respect Ready To Receive/Discharge The Cargo In Safe Condition. • The Connection Of All Cargo Hoses Is To Be Supervised By A Licensed Deck Officer And The Bunker Hose By The Chief Engineers. • When Making Connection Prior To Loading Or Bunkering, The Chief Officer Is To Assure Himself That Adequate Allowance Is Made For The Movement Of The Vessel To Ensure Safe Transfer Of Cargo Or Bunkers • Cargo And Bunker Manifolds Not In Use Are To Be Securely Covered Using A Blank Flange. • Every Hole In The Flange Connection Is To Be Fitted With A Bolt Of The Proper Size And Length Tightened Properly With A Gasket. •
Only Steel Manifolds’ Reducers And Spool Pieces Are To Be Used.
• Pressure Gauges Before To Commencing The Loading Operations Must Be Properly Installed At The Cargo Manifolds. • No Cargo Or Bunkering Operations Are To Commence Until All Scupper, Including Those On The Poop Deck Have Been Properly Plugged And Checked At Frequent Intervals That The Plugs Are Properly Set And Are Tight. Do Not Leave Unattended When Draining Off Accumulated Water Overboard. • Bags Of Oil Absorbent Material Should Be Placed At The Manifolds In Case Of Oil Splashes On Deck During Handling Hoses • The Cargo Officer Is Responsible For The Routine Operation And Inspection Of All Cargo System. Defects Should Be Brought To The Immediate Attention Of The Master And Chief Engineer. 6.3.1
Cargo Measurement Equipment
This Section Report The Main Equipment Which May Be Required To Ensure Accurate Cargo Measurements: •
• Ullages Tape: Ullage Rule/Bob Or Electronic Tape. For Operational Instructions Refer To Manufacturers’ Handbook With Particularly Attention To Static Electricity Problems.
•
• Automatic Tank Gauges (Where Fitted) : Used To Monitor Levels In Cargo Tanks During Transfers. When Reliability And Accuracy Allow These Should Be Used For Topping Off (In Some Terminals This Is Compulsory), But Final Tank Ullages Will Normally Be Carried Out By Use Of A Manual Steel Tape.
•
•
High Level/Overflow Alarms (Where Fitted) :
Should Be Kept In Good Working Condition, Regularly Calibrated And Operational. •
• Oil/Water Interface Detector : This May Be A Function Of The Electronic Ullage Tape Or An Independent Item. Provided There Is Sufficient Depth Of Water To Activate The Sensitive Element; The Use Of This Equipment Is Preferred To Water Finding Paste. The Equipment Should Be Maintained In Good Order. For Operating Instructions Refer To Manufacturers’ Handbook.
•
• Sample Equipment : Vessels Fitted With Vapour Locks Should Carry Equipment That Enables Normal Cargo Samples To Be Taken Via These Fittings. Other All Vessels Should Have A Bottle Sampler.
•
• Vapour Locks (Where Fitted): These Fittings Should Be Used For Ullaging, Temperatures, Water Dips And Samples So As To Reduce Cargo Vapour Loss/Emission.
•
• Digital Thermometer: Electronic Thermometer Which May Be Integrated With The Electronic Ullage Tape. Should Be Accurate To 0.2 Degree Centigrade. This Equipment’s Accuracy Should Be Checked Against A Mercury Reference Thermometer Prior To Measurements Being Taken, And The Results Recorded In The Cargo Book.
•
• Sounding Rods And Water Finding Paste : Water Finding Paste Are Applied To Innate Bobs Or Rods Which Are Lowered To The Bottom Of Ships’ Tanks, Via Vapour Locks If Fitted. For The Use And The Store Of The Water Finding Paste Should Be Strictly Observed The Manufacturer’s Instruction. For A Reliable Value The Paste Should Be Immersed For A Period Between 30 And 60 Second Depending On Type Of Paste.
6.4 Slack Tanks • According A Safe Stability The Number Of Slack Tanks, Must Be Kept At A Minimum Consistent With Loading Instructions. For More Details Refer To Stability Booklet. 6.5 Pre Transfer Cargo Conference • Oil Pollution From Tankers Usually Occurs While Loading Or Discharging Cargo. Failure Of Vessel And/Or Terminal Personnel In Charge Of The Cargo Transfer To Understand The Planned Transfer Operations, Capacities And Characteristic Of Vessel/Shore Equipment And Emergency Shutdown Procedures Contribute To The Risk Of Oil Pollution.
• Vessel And Terminal Personnel In Charge Of Oil Transfer Should Always Hold An Effective Pre-Cargo Transfer Conference. This Conference Should Include A Discussion Of An Agreement On The Following Items: • • • • • •
• Grades, Quantities, Segregations, Start/Stop Times Of Each Cargo Parcel To Be Transferred. • Ship-Shore Communication Procedures To Be Followed During Standard Transfer Operations And Any Special Communications Procedures To Be Followed In Case Of Emergency, Including An Oil Spill. • Notification Of Procedures/Contacts In The Event Of An Emergency Closure Of The Shore Valve, So As To Enable The Vessel To Activate Emergency Cargo Pump Stops. • Prompt Notification Of Terminal Contact In The Event Of Valve Failure, Imminent Overflow, Or Other Occurrence On Board The Vessel That Would Require An Immediate Terminal Shutdown Of The Loading. • Topping Off Procedures • Line Loading Arm Or Hose Draining Procedures For Further Guidance On This Subject Refer To International Safety Guide For Oil Tankers And Terminals (I.E. Isgott) Chapter 4, 5 And 7. Also, Appendix A Of Isgott Provides A Comprehensive Ship/Shore Safety Checklist In Case This Is Not Readly Available From Terminal.
6.6 Checklist • Prior To Any Cargo Operations Being Carried Out The Ship/Shore Checklist Are To Be Completed, Even If This Is Not Requested By The Terminal. Guidelines For The Compilation Of This Checklist Are Contained In Isgott Publication, Appendix A. 6.7 Cargo Record Book • Master Shall Assure Himself That The Following Information Is Entered In The Cargo Record Book: • • • • • • •
• Grades And Quantities Of Each Cargo Handled In Each Port. • The Applicable Seasonal Loading Mark. • Cargo Deadweight, Stress And Trim, Draft Data. • Ullages And Water Innage Of All Tank Before And After Loading And Discharging At Each Terminal. • Cargo Shifting Made For Affecting The Trim And Stress Of Vessel • Details Of Any Loss Of Cargo Which May Have Occurred During The Voyage. • Tanks Washed With Crude Oil With Full Details. Eventual Other Information Is Not Limited And Can Be Recorded.
6.8 Petroleum Hazards 6.8.1
General
Petroleum Must Always Be Treated With Respect, For In Varying Degrees It Possesses Two Proprieties Which, Given The Right Conditions, Can Harm Personnel And Property. The First Of These Is “Flammability”, I.E. Ability To Burn, Which Practically All Petroleum Grades Possess. The Lighter And More Volatile The Petroleum, The More Readily It Will Burn And The More Likely It Is To Explode On Igniting. The Second Is “Toxicity”, I.E. The Ability To Poison The Human System Either Directly Or Indirectly By Depriving It Of Oxygen Thus Causing Unconsciousness, And Eventually If Exposure Continues, Death. To A Large Extend, Petroleum Provides Its Own Safeguards By Gases And Smells, Which Serve As A Constant Reminder To Personnel Not To Ignore Obvious Precautions Such As Keeping Source Of Ignition Away, And Avoiding Too Close And Too Long Exposure To Its Vapours. There Are, However, A Number Of Fewer Obvious Hazards, Particularly The Possible Ignition Of Flammable Vapours By The Generated Sparks From Static Electricity. For These Purpose Master Should Refer To “Tanker Safety Guide” Published By International Chamber Of Shipping And To Safety Manual Furnished By Company. 6.8.2
Hydrogen Sulphide (H2s)
A Considerable Number Of Crude Oils, Mostly From The Middle East Contain Hydrogen Sulphide. This Is An Evil Smelling Poisonous Gas Which May Cause Death Depending Upon The Concentration Of Gas In The Air Inhaled And Also The Length Of Exposure. Great Care And Attention Is Required When Handling Crude Oils, With An H2s Content. The Personnel Should Stand At A Right Angle To The Wind Direction When Ullaging Tanks This Means That They Should Stand Sideway To The Wind Direction So That Any Vapour Coming From The Tank Opening Is Carried By The Wind Clear Of Them And They Are Clear Of Any Eddies Immediately To Windward. 6.8.3
Cleaning After “Leaded” Cargoes
In The Case Of Shore Storage Tanks Containing Leaded Gasoline, Very Extensive Precautions Are Laid Down For The Care Of Personnel. This Is
Because The Tanks Concerned Are Usually Cleaned Only After Long Intervals, During Which Time They Have Replenished On Many Successive Occasions And Deposit Of Tel (Tetra-Ethyl-Lead) Or Tml (Tetra-MethylLead), With Other Sediments, May Have Formed In The Tank Bottoms. These Conditions Do Not Occur In The Tanks Of Vessel Carrying Leaded Gasoline Cargoes, And Consequently, It Is Not Necessary To Take Such Stringent Precautions As Are Applicable To Shore Tank Cleaning Operations. It Is, Nevertheless, Recommended That All Men Engaged On This Work Should Wear Protective Clothing, E.G. Rubber Boots, Tank Gloves And Boiler Suit; Also, That Before Meals And At The End Of Each Day’s Work, The Exposed Parts Of The Body Should Be Thoroughly Washed And Clothing Changed. 6.8.4
Products Containing Benzene / Toluene
Certain High Aromatic Grades In Various Categories With Higher Then Normal Benzene And Toluene Contents Are Often Handled By Terminal Personnel In The Same Manner As Pure Benzene. Because Of The Cumulative Toxic Effects Of Pure Benzene Very Extensive Precautions Are Laid Down For The Care Of Personnel Regularly Engaged In Handling Such Products. Occasional Handling Does Not Necessitate The Application Of Such Stringent Precautions. However When Aromatic Products With High Benzene Contents Are Handled On Board Tankers The Attention Of Master Is Drawn To Any Relevant Precautions Laid Down By Company And By Ics’s Safety Publications.
7.
Loading 7.1 General
Ships Are Required To Load Cargo As Rapidly As Possible By Day And Night In Accordance With The Terms Of Their Charter Parties. This Means, Whether Single Or Multi-Grade Cargoes, That Ships Are Expected To Load As Fast As The Shore Can Supply Or They Can Safely Receive. The Question Of How Fast A Ship Can Load Is The Responsibility Of The Master, Having Regard To Their Company Instructions, The Charter Party And The Experience Of Ship’s Personnel. 7.1.1
Procedures For Oil Residues
Unless Otherwise Specified In The Voyage Orders, The Vessel Should Arrive At Load Port With Clean Ballast Having Followed Load On Top Procedures. Depending On Charterers Requirements The Slop May Be Handled In One Of The Following Ways: • •
7.1.2
• Pumping The Slops Ashore At The Loading Terminal • Retaining The Slops On Board Loading The Incoming Cargo On Top Of Them • • Retaining The Slops On Board But Segregated By Incoming Cargo. • • If Last One Procedure Is Required, It May Be Possible To Discharge The Slop At The Nominated Disport If Reception Facilities Are Available. It May, However, Be Necessary To Retain The Residue For More Than One Voyage. Arrival Ballast
Vessel Shall Arrive At Loading Port With Minimum Ballast In Respect Of Safe Navigation And Port Requirements. Cargo Officer, Preparing Ballast Layout, Should Consider The Safe And Best Performance Of Discharge. 7.1.3
Simultaneous Deballasting/Loading
Simultaneous Deballasting/Loading Should Not Be Attempted Unless Separation Is Not Granted By At Least Two Valves And The Master Is Satisfied That The Two Valves Are Tight. 7.1.4
Permanent Ballast
Permanent Ballast May, Of Course, Be Discharged Simultaneously To Loading Cargo. This May Be Required To Maintain A Safe Draft Reducing The Effect Of Wind In The Light Ship Condition. 7.1.5
Draining Cargo Lines
At The End Of Deballasting, Cargo Lines Should Be Drained Into After Most Cargo Tanks And Stripped Into Ashore Facilities, Than Final Discharge Of Ballast Must Stripped Through The Small Diameter Line To The Manifold Valve. 7.1.6
Tank Inspection
Prior To Loading The Cargo Tanks Should Be Inspected By Terminal Representative And/Or Independent Inspector (If Nominated) With The Presence Of Cargo Officer.
O.B.Q. Certificate Must Fill Up Reporting The Amount In Cubic Metres Of: • • •
• • •
7.1.7
Liquid Oil Not Liquid Oil Water Linig Up Cargo System
Before Start, Loading Deck And Pumproom Valves And Lines Should Be Set. Loading Should Be Set So That Cargo Flows Through Loading Drop Valves Bypassing The Pumproom. Pumproom Cargo-Line Valves Should Be Firmly Shut And Sea Chest Valves Lashed Shut. Deck Valves That Are Not Going To Be Used Should Be Lashed Shut 7.1.8 Setting P.V. Valves The Vessel Should Use The Close System. All Cargo Tank Vents Should Be Set To The Loading Position. Ensure That Inert Gas Plant (If Fitted) Is Shut Down, The Deck Isolation Valve Is Shut And The Main Inert Gas Venting Valves Are Open. 7.1.9 Opening Manifold Valve The Manifold Valve Should Remain Shut Until The Cargo Officer Is Satisfied In All Respect With The Vessel’s Readiness To Load. 7.2 Loading Plan • Book”.

Guidelines For The Compilation Of This Check List Are Contained In Isgott Publication, Appendix A. 7.3 Start Loading The Initial Flow-Rate Should Be Low In Order To Check : • • •
• • •
The Cargo Flow In The Corrected Tanks The Cargo Is Not Flowing Into Uncorrected Tanks Any Possible Leakage Of Oil
After These And If No Problem Rise Cargo Officer Shall Advise The Terminal Operator That The Vessel Is Ready And Agree For Full Loading Rate. 7.3.1 During Loading If The Officer In Charge Detects Or Suspect Any Faults In The Loading System He Should Immediately Require That Loading Be Stopped Until Any System Faults Have Been Corrected. The Failure Must Be Recorded In A Cargo Book. Both Cargo Officer And Terminal Representative Shall Decide When To Resume Loading. The Ullages Of The Tanks Being Loaded Should Be Monitored Frequently And Regularly, Especially When Tanks Are Approaching The Topping Off Range. Full Precaution Must Be Done On Changing Tanks Operation In Order To Avoid Over Pressure On Ship’s And Shore’s Lines. Also The Cargo Tanks Already Loaded Should Be Checked At Regular Intervals In Order To Avoid Cargo Overflow Due Any Possible Leakage Of Cargo Valves. 7.3.2
Topping Off & Checks After Loading
Adequate Notice Should Be Given To The Terminal When Approaching The End Of Cargo. The Last Part Of The Loading Operation Should Be Done At A Reduced Rate. The Chief Officer Should Satisfy Himself That There Are Terminal Staff On The Jetty Ready To Shut Down, Prior To Completion Of Cargo.
When Ordering The Stop Of Cargo, Time Should Be Allowed For The Terminal To Shut Down. Space Should Be Allowed In The Tank For This, And Also For Draining Loading Arms. As Soon As The Loading Arms Have Been Drained, The Cargo Officer Should Ensure That All Valves In The Cargo System Are Closed, That All Appropriate Tank Openings Are Closed, And That Pressure/Vacuum Relief Valves Are Correctly Set. 7.4 No Shore Facilities For Dirty Ballast • This Is Very Common Pollution Cause, Occurring At Load Ports, Which Do No Have Dirty Ballast Handling Facilities. • Most Important Prevention Steps Are A Thorough Cleaning Of Vessel’s Tanks And Pipelines Holding Or Transferring Ballast. • Establish Procedures Which Allow For Some Clean Ballast To Be Properly Discharged At Sea Prior To Arrival At The Loading Port. This Will Flush The Sea Chests And Guard Against The Possibility Of Trapped Oil Escaping In Port. • Require That All Ballast Tanks, Including Segregated Ballast Tanks, Be Carefully Inspected For Oil Content Prior To Discharge. We Recommend That A Small Piece Of An Oil-Absorbent Pad Be Lowered To The Surface Of The Ballast Water For A Physical Check Of The Water In Addition To A Visual Inspection. This May Require Removal Of Tank Cleaning Opening. • It Is Also Recommended That A Cargo And Ballast System Pressure Test Be Carried Out During Each Ballast Passage Prior To Loading Cargo To Verify That Lines And Valves Are Tight. Records Of These Tests Should Be Maintained. • One Should Ensure That The Oil Content Monitor/Recorder Is Properly Operating At All Times While Deballasting. 7.5 Dirty Ballast Shore Facilities Whenever Possible, Vessels Should Discharge Their Ballast To Shore Facilities If These Are Available. If Vessel Discharges Dirty Ballast To Shore Facilities, Procedures To Retain Slop Oil On Board May Be Required. For Further Guidance On These Subjects Refer To Pollution Prevention Manual And To Isgott Chapter 7.5. 7.6 Inspection Before Loading •
Prior To Inspection Cargo Lines Should Be Drained Ashore.
• All Material Concerning The Quantity That Remains On Board Should Be Determined As Liquid, No Liquid And Free Water. If Sufficient Quantity Is Available Then A Sample May Be Taken And One Sample Stored On Board. • A Temperature Measurement Should Be Taken If Sufficient Liquid Available. The Temperature Should Be Taken From The Mid Point Of The Oil Layer. Solid And Small Quantities Of Liquid For Which A Temperature Cannot Be Taken May Be Assumed To Be At Standard Temperature. • Bunker Survey And/Or Lel Gas Check In The Bunker Tankers Can Be Carry Out If Requested By Independent Inspector. • Any Slops That Are To Be Commingled With The Subsequent Cargo Are To Be Recorded As O.B.Q. (On Board Quantity). For Official Document Refer To 4.1.6. 7.7 Calculation Of On Board Quantity (O.B.Q.) • The O.B.Q. Should Be Calculated And Recorded Prior To The Commencement Of Loading Cargo. •
The Quantity Of O.B.Q. Should Be Determined As Follows:
•
• Use Special Wedge/Dip Tables If Carried, Or The Wedge Formula If Liquid Does Not Cover Bottom Of Tank. • Use Trim/List Correction If Liquid Covers Entire Bottom Of Interested Tank, And Compute The Quantities Using A Calibration Table. • For The No Liquid Oil Use Calibration Table Without Correction For Trim And List
• •
7.8 Cargo Measurement • The Measurement Must Be Taken With All Precaution And Practicable Accuracy. Prior To Topping-Off Operations Compare Local And Remote Readings When Stowed And At Ullage Depth For Any Discrepancies. • The Responsibility For The Quantity Of Cargo On Board Rests Entirely On The Master And There Is No Need For Terminal Representative To Witness Ship’ Staffs’ Measurement Of Cargo. At Ports Where Local Regulation (E.G. Custom) Requires Shore Or Local Authorities To Witness/Carry Out Cargo Measurement, Master Must Naturally Assist In Every Way. 7.8.1
Standard Instruments
Automatic Tank Gauges, Where Fitted And When Reliability And Accuracy Allow These Should Be Used For Topping Off (For Some Terminals This Procedure Is Compulsory). Final Tank Ullages Will Normally Be Carried Out By Use Of A Manual Steel Tape.
Vessels Fitted With Vapour Locks Must Use This Fitting For Ullaging, Temperatures, Water Measurement, Sediment Measurement And Sample So As To Reduce Cargo Vapour Loss/Emission. For The Safety Purpose Reference May Be Done To Isgott, Chapter 7.1 7.9 Inert Gas System (If Fitted) •
Refer To Chapter “Safety”, Page 3 Of 5 Of This Manual.

Internal Transfer Of Cargo At Sea On Loaded Passage
• Transfer Of Cargo Between Ships’ Cargo Tanks Should Be Only Carried Out If: • • •
• • •
An Emergency Arises For Drafts Problems On Arrival Port (Informing Before The Charterer) Others (Always Informing Before The Charterer)
When There Is Transfer Of Cargo During The Loaded Passage, The Ullages Of Involved Tanks Must Be Taken Before And After The Transfer. Ullage Measurements Are Taken Also In Those Tanks Not Involved In The Transfer Operation To Ensure Valve Integrity. Temperature Must Be Measured In Those Tanks Where Cargo Transfer Has Occurred And The Redistributed Cargo Must Be Calculated To Make Certain No Losses Have Occurred. Each Completed Operation Shall Be Reported On Oil Record Book, Part Ii, As Indicated By Marpol 73/78 (Refer Annex J, Appendix Iii - List Of Items To Be Recorded: Item B “Inteernal Transfer Of Oil Cargo During Voyage”) 7 .11 Ship To Ship Transfers Both Tankers Should Comply Fully With The Safe Precautions As Contained In The Ics/Ocimf “Ship To Ship Transfer Guide (Petroleum)” Last Edition. 8.
Discharging 8.1 General • It Will Be Realised That, Whether Shore Facilities Are Restrictive Or Not, The Ability Of A Ship To Achieve A Good Discharge Performance Depends Upon All The Cargo Handling Plant Being Efficiently Maintained, As Well As Skilfully Operated. • Good And Safe Discharge Performance Demands An Intelligent Use Of The Tanker’s Pumping Capabilities And Company Expect Masters To Ensure That Their Responsible Personnel Are Aware Of This And Carry It Out.

Company Wish To Emphasize That The Above Obligation On Masters Refers Particularly To The Taking And Recording Of Cargo Measurement Data, I.E. Ullages, Temperatures, Specific Gravities, And Where Applicable, Water Dips. • To Ensure That The Tankers In Their Employment Use Standard Instruments For Cargo Calculation Purposes Company Supply Each Ship With Proper Instruments. • Vessels Fitted With Vapour Locks Should Use This Fitting For Ullaging, Temperatures, Water Measurement, Sediment Measurement And Sample So As To Reduce Cargo Vapour Loss/Emission. • The Precautions To Be Taken And The Procedures That Should Be Observed During Cargo Measurement Are Reported As Guide In Isgott Publication, Chapter 7. 8.4 Crude Oil Washing (If Fitted) • •
The Following Advantages Can Be Attributed To C.O.W. : •
Reduce The Potentiality Of Sea Pollution
• • •
• Less R.O.B. On Completion Of Discharge • Increase The Shore Figures And Produce More Space Available For Next Cargo • Save Of Time And Bunkers Required For Subsequent Clean Ballast
If Fitted Reference Should Be Made To The “Crude Oil Washing Manual” And Isgott Recommendations Chapter 8.4 And To The Imo Publication “ Crude Oil Washing System” 8.4.1 Crude Oil Washing At Sea Crude Oil Washing Should Only Be Carried Out At Sea At Express Request Of The Charterer, And Must Be Completed Before The Ship Leaves Its Final Port Of Discharge. Where Any Tank Is Crude Oil Washed While The Ship Is At Sea Between Multiple Discharge Ports, The Tank Shall Be Left Empty And Available For Inspection At The Next Port. 8.5 Inert Gas System (If Fitted)
Refer To Chapter “Safety”, Page 3 Of 5 Of This Manual 8.6 Ballasting • Prior To Start The Ballasting And Before Opening Sea Valves Following Procedure Should Be Observed: • • • •
• Set Line For Ballasting With The Seachest Valve Kept Closed • Drain With Highest Accuracy All Oil From The Interested Pump And Cargo Lines • Start Up The Pump At Reduced Revolution And Check If Possible That No Positive Pressure Exist Between The Pump And The Sea Valve • As Soon As Pump Is Running Steadily, Start To Open The Seachest Valve, Increasing The Pump Speed As The Pump Start To Take Up Suction.
The Ballasting Operation Should Be Reported In The Cargo Book As Part Of The Overall Discharge Plan. Terminal Representative Should Be Advised When Ballasting Interests Cargo Tanks Already Discharged And/Or Cargo Tanks Empty On Arrival. The Agreement Of The Terminal Representative Should Be Obtained Before The Simultaneous Handling Of Cargo And Ballast, Other Than Segregated Ballast, Take Place. Independent Cargo Inspector, If Nominated, Should Be Advised So That Both Cargo Officer And Independent Inspector Shall Check With All Practicable Accuracy The R.O.B. Quantity. An Appropriate Report Will Be Issued And Duly Signed By Both Parties.
9.
Sampling And Samples 9.1 General • Sampling Of Cargo At Loading And Discharging Ports Is Necessary For Quality Control Purposes, Particularly For Sensitive Products. • Samples Taken At Loading Ports Are Frequently Placed On Board For Delivery To Discharging Ports And Masters Are Requested To Ensure That The Sample Are Delivered In The Condition In Which They Are Received. • Usually The Samples Are Taken By Terminal Staff Or By Independent Inspector With Ship Representative As Witness But Some Time The Vessel Is Asked To Take Samples. 9.2 The Sample The Product Is Tested By Various Method For The Determination Of Physical And Chemical Characteristics, Therefore The Sample Should Be Highly Representative. The Representative Characteristics Of The Sample Are Numerous And Depend On The Type Of Material Being Sampled. The Tank Or Bottle That Will Receive The Oil Should Be Perfectly Clean And Dry. 9.2.1
Dynamic Sampling
Used When Samples Are Drawn From An Oil Flowing In One Line. Require Special Equipment Usually Working In The Shore Line Or At The Manifold. 9.2.2
Static Sampling
Used When Samples Are Drawn When The Product Being Sampled Is At Rest. 9.2.3
Average Sample
Average Sample Is One That Consists Of Proportionate Parts From All Section Of One Single Tank. 9.2.4
Composite Sample
A Composite Sample Is Obtained Mixing The Samples Of Each Tank In Proportional Parts. 9.2.5 Running Sample Is Obtained By Lowering A Special Bottle That Each Empty The Bottom Of The Tank And Returning To The Top Of The Oil At A Uniform Rate Of Speed.

Fire Fighting Equipment
Immediately Before On Arrival At The Loading Or Discharging Port, The Ship’s Fire Hoses Should Be Connected To The Fire Main, One Forward And One Aft Of The Ship’s Manifold. If Praticable A Fire Pump Should Maintain Pressure On The Ship’s Fire Main While Cargoor Ballast Is Being Handled. If Not Possible The Fire Pump Should Be In Stand By Condition And Ready For Immediate Operation. Monitors Should Be Ready For Use. Portable Fire Extinguishers, Preferably Of The Dry Chemical Type, Should Be Placed Near The Ship’s Manifold. A Check Should Be Made To Confirm That Both Ship And Shore Have An International Shore Fire Connection For The Transfer Of Water For Fire Fighting. 11.4

For Further Details On This Subject Refer To Isgott Chapter 6.9 As Well As Company Manual “Pollution Prevention”
12.3 Oil Record Book All Cargo/Ballast Operations Must Be Duly Recorded In The Oil Record Book As Required By Marpol 73-78 Annex I. This Log Is Regularly Inspected By Port Authorities. The Instructions For Use And Compilation Of This Book Are Within It. 13.
Cargo Heating 13.1 General • The Heating Requirements For Different Grades And Circumstances Are Based Upon A Number Of Factors Which Balance The Cost Of Heating Against The Results To Be Achieved Thereby. • Characteristics Which Govern Whether An Oil Should Be Heated Or Not And To What Temperature, Are “Viscosity And/Or Pour Point” . The Need For Heating For Viscosity Reasons Is Self-Evident As Is That For Pour Point With Respect To The High Pour Point Cargoes. 13.2
Heating Requirement
• When Loading Orders Are Received, Company And/Or Charterer Give Instructions For Heating The Grade To Be Loaded (If Any). Agents Or Suppliers May Issue More Heating Instructions. Should There Be Any Discrepancy Between These Instructions And Those Sent By Company/Charterer Loading Must Not Be Delayed But Company/Charterer Should Be Informed By The Most Rapid Means, Together With Any Reason For The Difference Put Forward By The Loading Port. The Master Will Then Be Advised Which Instructions To Follow. 13.3
Inability To Comply
• In The Event Of Masters Being Unable For Any Reason To Comply With The Required Heating Instructions, Or If They Anticipate Difficulty In Heating The Cargo To The Necessary Temperature During The Voyage, Before Commencing To Load They Must Radio Charterer/Company Direct And Inform Agents . • If Difficulty In Complying With The Heating Instructions Is Experienced During The Actual Loaded Voyage, The Master Should Immediately Inform Charterer/Company By Radio, Stating The Reasons For His Inability To Carry Out The Heating Instructions. 13.4
Testing Of Heating Coils
• When Heating Cargo Is Required The Heating System Must Be Tested Prior To Arrive At The Loading Port.
• If Any Coils Are Thought To Be Leaking Within The Cargo Tanks, Any Efforts Are To Be Made To Repair These Coils Following The Required Safety Procedures Described In Safety Manual. • When Such Repairs Are Not Practical Then The Heating Coil Concerned Should Be Blanked Off. 13.5
Commencement And Duration
• Unless Otherwise Instructions It Is Left To The Master’s Discretion As To When Heating Should Be Commenced To Ensure That The Ship Arrives At The Discharge Port With Cargo Heated To The Required Temperature. • Whilst With The Majority Of Grades It Is Not Necessary To Maintain Heating Throughout The Voyage, Master Should Not Hesitate To Do This If There Is Any Doubt Of The Ship’s Ability To Rise The Cargo Temperature To That Required For Discharge. • With Certain Very Viscous, Or High Pour Point Cargoes It Is Essential To Heat Throughout, To Keep The Cargoes In A Pumpable State. 13.6
Discharging Temperature
• The First Essential To Ensure The Success Of This Operation Is To Arrive At The Port Of Discharge With The Cargo At The Correct Temperature. • All Grades Of Cargo Must Be Discharged In The Shortest Possible Time, But With The Cargoes Requiring Heat The Time Taken To Discharge The Contents Of A Compartment Also Determines The Amount Of R.O.B (Remain On Board Quantities). This Must Be The Absolute Minimum, And The Surest Way Of Effecting This Is To Maintain The Correct Temperature As Tanks Are Emptied, And Ensure That The Draining Rate Is As High As Possible So That Drainings Do Not Cool And Become Unpumpable Before The Tank Is Empty. • The Order In Which The Various Compartments Are Discharged Is Also Important, Particularly When The Sea Temperature Is Low. • •
•
The Following Remarks Are, Therefore, For Guidance Only: • Of The Three Compartments Of The Tank, The Wing Components Are The Most Exposed To The Cooling Effect Of The Water Outside And, Theoretically, The Order Of Discharge Should Be To Empty The Two Wing Compartments, Followed By The Centre Compartment, Assuming One Pump Only Is Available. • Provided Contrary Instructions Are Not Given For A Particular Grade Of Cargo, As A Discharge Of Cargo From Individual Tanks Progresses, The Steam On The Heating Coils Of These Tanks Should Be Gradually Reduced, And On Reaching A Depth Of A Few Inches Above The Coils The Steam Should Be Shut Off Completely. This Prevents The Cargo Becoming Heated
Above The Permitted Maximum And Also, In The Case Of Certain Crude Oils, Prevents The “Gassing” Of The Pumps. 13.7
Overheating
• Effects Of This Are Not So Apparent, But Nevertheless It Is Undesirable For The Following Reasons: • • •
• Unnecessary Expenditure Of Bunkers. • Deterioration Of Crude Oil Cargoes Through Loss Of Light Fractions. • Gasification Of Pumps During Discharge Often Resulting In Excessive Draining Times.
Masters Need Have No Fear Of Loading Cargoes At Temperatures In Excess Of That To Which They Are Allowed To Heat, As The Temperature In These Case Is Invariably A Carefully Controlled Refinery Process. By Recording The Loading Temperature On The “Cargo Documents” And On Cargo Book Their Interests Are Safeguarded. 14.
Cargo Loss Control 14.1
General
• All Cargo Measurements Are To Be Taken With All Practicable Accuracy. The Responsibility For The Care Of Cargo From The Time It Passes The Ship’s Manifold On Loading, Until It Passes The Ship’s Manifold Again On Discharge Rests Always With The Ship. • Taken:
In Order To Minimize The R.O.B. Following Measures Are To Be
•
• Stripping Is To Continue Until All Possible Liquid Cargo Is Discharged. If Unusual Quantity Of Liquid Remains On Board, The Company Must Be Advised Of The Reasons.
•
• Main Cargo Lines Are To Be Drained Into Last Tank Before Final Stripping Ashore • Last Tank (I.E. Slop Tank) Should Be Discharged By Main Cargo Pump To Lowest Possible Level In Tank, And The Remainder Cargo Should Be Stripped Shore.
•
For The Purposes Of Cargo Measurement An Independent Inspector May Attend Cargo Operations. Full Cooperation Is To Be Given And A Deck Officer Is To Assist Cargo Inspector During Ullaging And Sampling And The Inspection Should Be Witnessed And Agreed By Both Parties.
Large Discrepancies In Figures, If Any, Between Ship And Shore Figures Should Be Investigated And If Still Exist The Reasons For These Should Be Commented On The Official Ullage Report Form. 14.2 Cargo Calculation • The Ship’s Ullage Report Should Contain Following Information As Minimum: Tov Fw Gov Vcf Gsv Tvc Obq Rob Vef Wcf Drafts Trim
Total Observed Volume At Observed Temperature Free Water On Tank Bottom Determined By Water Cuts/Interface Gross Observed Volume (Tov - Fw) At Observed Temperature Volume Correction Factor Gross Standard Volume (Gov X Vcf) Corrected At 60f/15c Total Calculated Volume (Gsv+Fw). On Board Quantity Prior To Loading (Flowing Oil+ No Flowing Oil +Water) Remaining On Board After Discharge (Oil+No Flowing Oil+Water) Vessel Experience Factor Weight Correction Factor (To Convert Volume / Weight) Fwd - Center - Aft If Applied Or Not
14.3 Cargo Disputes / Complaint There May Be Occasions During The Course Of Normal Cargo Handling Operations When Disputes Or Complaints Arise Over The Quantity And/Or The Condition/Quality Of The Cargo. From A Practical Point Of View These Matters Are Usually Dealt With On The Spot And Resolved Satisfactorily But, In Order To Facilitate Any Investigations Which May Be Necessary At A Later Date, Copies Of Any Correspondence In The Nature Of A Letter Of Protest Or Written Explanations Exchanged Between The Ship And The Shore Should Be Sent To Charterers As Well As To Company. The More Usual Kinds Of Dispute Or Complaint And The Action Can Be Summarised As Follow: • • Differences Bill Of Lading / Ship’s Figures • The Quantity Stated In The Bill Of Lading Should Be Checked By Master Against The Quantity Determinant From The Ship’s Ullage Measurement. If There Is A Difference In Volume Of More Than 0.2% (Considering The V.C.F.)And Such Difference Is Not Due To Any Known Inaccuracy In The Ship Calibration Table, A Letter Must Be Written By The Master To The Cargo
Supplier Drawing Their Attention To The Discrepancy And Stating That The Bills Of Lading Are Accordingly Signed Under Protest, But In No Circumstances Should The Bill Of Lading Be Endorsed To This Effect Or Altered In Any Way. If Different Policy Is Used By Charterers That Should Be Followed - Differences Bill Of Lading / Outturn Figures Although On Occasion The Cargo Receiver Protest To The Ship Regarding The Quantity Of Cargo Delivered, Such Complaints Usually Take The Form Of A Letter Of Protest And All That Is Necessary On The Master’s Part As Far As This Document Is Concerned Is To Sign It As “Received” And Make No Other Comment Whatsoever. • • Contamination • In The Event Of Contamination Of Cargo Occurring On Board The Ship, The Master’s Attention Will In Most Case Be Drawn To This Fact By The Cargo Suppliers Or Cargo Receivers In Sufficient Time To Enable The Ship And The Shore To Take Steps To Deal With The Problem From A Practical Point Of View. • The Cause Of Contamination May Not Always Be Immediately Apparent But, In Any Case, Any Formal Complaint From The Shore Should Generally Speak Be Dealt By A Simple Acknowledgement Although It May Sometime Be Necessary For The Master To Provide The Shore Installation With More Detailed Explanations Of The Cargo Operations Carried Out On Board. It Will Be Of Assistance In Investigating Any Claims Which May Arise If A Copy Of The Master’s Report With Copies Of Any Correspondence Exchanged With The Shore Is Sent To Company And To Carterers. •
• Miscellaneous • Any Other Cause For Complaint Which May Be Made By The Cargo Interests Against The Ship, Apart From Those Already Mentioned An Usually Be Dealt Within Much The Same Way. • If, For Example, The Cargo Carried Normally Requires Heating And On Arrival At The Discharge Port The Temperature Of The Cargo Is Found To Be Below Or Above That Of The Temperature Stipulated In The Charterers Heating Instructions, Cargo Receivers Will Usually Issue A Letter Of Protest Specifying The Numbers Of The Tanks Involved And The Temperature Of The Oil Contained Therein. In These Cases It Is Only Necessary To Acknowledge Receipt Of Such Protest By Signing It As “Received”
