How to Construct 1 lakh inch dia pipe within 3 months???????

Piping Terminology; 1. Transmition pipelines: Usually long, relatively large diameter lines, May Transport Hydrocarbon fluids and or Gas. from producing fields to processing plant or refineries.. From plants and refineries to marketing centers 2. Flowline: Two phase lines (Non separated HC with two phase (liquid and gas) flows before entering the inlet separator), connecting wells to production manifolds. range from 2 - 20 inches. 3. Trunkline: Two or more well flow lines connected to a larger line that carries the combined well stream to the production manifold. range from 10 to 42 inches. 4. Injection lines: Transport high pressure gas or water to wellheads for injection into the producing formation. Fluids are injected for: Reservoir pressure performance, production enhancements, conservation of gas, Gas Lift, Produced water disposal, water flood, steam flood. 5. Piping / Plant (Facility) Piping (on plot): Piping within the well-defined boundaries of the processing plants, piping compression station or pumping station. Used for a variety of fluids within those boundaries as required.

A --- ACTIVITY DESCRIPTION   

Mobilization of manpower, machinery etc ROW survey and marking, clearing and ROW grading Trenching Stringing Bending Welding X- ray / NDT ( above ground) , Joint Repair , Joint Coating Trench bottom padding ,Lowering, top padding , backfilling Tie - in - joints and mainline valves, welding-ray and repair , joint coating Tie - in - Joint top padding and backfilling Hydrotesting Restoration of ROW. B --- CONSTRUCTION SCHEDULE THE EQUIPMENT AND MANPWER PLANNING PLANING ie THE PLANNING FOR RESOURCE ASSIGNMENT IS TO BE DONE FOR THE ABOVE PIPELINE SCHEDULE. FIRSTLY FOR THE PURPOSE OF EXECUTION THE PIPELINE IS TO BE DIVIDED INTO SECTIONS OF APPROPRIATE LENGTHS KNOWN AS SPREADS.I REQUEST YOUR ASSISTANCE IN FIRSTLY FIXING THE PROPER LENGTH , NUMBER AND ARRANGEMENT OF

SPREADS ALONG THE PIPELINE.I HAVE ALSO TO LOGICALLY PRESENT TO MY MANAGEMENT THE JUSTIFICATION (PREFERABLY CALCULATION TOO - IF APPLICABLE) FOR FIXING THIS SPREAD LENGTH. THEREAFTER THE RECOMMENDED DISTRIBUTION OF EQUIPMENT FOR EACH SPREAD (WITH RATINGS ie TONNAGE ETC OF THE EQUIPMENT) IE NO DOZERS , GRADERS , EXCAVATORS / POCLAIN ,ROCK - BREAKERS WITH HYDRAULICALLY OPERATED CHISELS,PIPE BENDING MACHINES PIPELAYERS/SIDEBOOMS , ETC IS REQUIRED TO BE PROVIDED.THIS DISTRIBUTION OF EQUIPMENT HAS TO BE LOGICALLY WORKED OUT AND IS TO BE BASED ON RECOMMENDED EQUIPMENT RATING , STANDARD MACHINEHOUR NORMS , AND TOTAL ESTIMATED QUANTUM OF WORK eg EARTHWORK / GRADING AREA ETC. LIKEWISE RECOMMENDED DISTRIBUTION OF MANPOWER, WELDERS, RIGGERS, INSULATORS, ETC IS TO BE WORKED OUT BASED ON ESTIMATED QUANTITY OF WELDING LENGTH AND WELD VOLUME ETC AND STANDARD MANHOUR NORMS FOR PIPELINE WELDING ETC. IT IS ALSO REQUIRED TO WORK OUT THE RATING AND DISTRIBUTION OF WELDING MACHINES FOR THE SPREADS SO CONSIDERED. ALL THE MANPOWER AND EQUIPMENT PLANNING ABOVE IS TO BE PRODUCED IN A SYSTEMMATIC, TRACEABLE AND VERIFYABLE MANNER. ANY HELP FROM PEOPLE EXPERIENCED IN THIS FIELD SHALL BE HIGHLY APPRECIATED. ESPACIALLY I REQUEST HELP FOR FIXING OF SPREAD LENGTHS ,NO OF SPREADS, RECOMMEN -DATION FOR RATING OF EQUIPMENT , MACHINEHOUR NORMS FOR EQPT WITH SPECIFIC RATING AND MANHOUR NORMS ESP FOR WELDERS. IN ABSENCE OF DETAILS REGARDING HARD ROCK / ROCK STRATA AND SLOPE (IE TERRAIN) THE SAME CAN BE SUITABLY ASSUMED AT PRESENT AND THE ASSUMPTION SO MADE HAS TO BE CLEARLY MENTIONED.THE SAME CAN ME MODIFIED AT A LATER STAGE AS MORE AND ACTUAL DETAILS COME WITH SOIL INVESTIGATION AND TOPOGRAPHIC SURVEY. TYPE C Answer I read your posts with interest. I have been involved in laying over 9,000 miles of pipelines on five continents in the last 52-years. I have worked as a spread engineer (for the contractors’ planning), as a pipeline bending engineer/bending foreman, as a pipeline superintendent and as a pipeline consultant. Could you supply the following information?

What country and area of that country is the job in? What is the expected weather? What are the different pipe thicknesses? What pipe yield-X-65 (?), X-70(?) or X-80(?) or what? Does the contractor have a choice of welding procedures-Manual (stick rod or Semiautomatic-maybe a combination of both) or pure automatic? Have you figured in two double-jointing yards? This is dependent on conditions (and widths) of roads to allow 24 meters to be hauled? Weight capabilities and weigh limits of bridges are also a consideration. Also running double-jointing yards assumes there will be a timely supply of single length joints to the yards. Can you estimate what per cent of total job are flat or rolling hills, swamps, sand or sand dunes, land requiring de-watering, sharp hills and mountains? What percent is normal dirt (easily cut by excavators or wheel trenchers), soft rock (like sandstone, sedimentary rock) or aggregate rock (like American caliche or African Laterite) or very hard rock (like granite, chert)? What is the countryside like? Open, deserts, farmers fields, lightly forested, heavily forested, rice fields, swamps or rainforest and jungles? What type of coating will be used?
