INTRODUCTION The Khor Al Zubair NGL Plant is located approximately 30kms to the south of Basra and currently operated by the South Gas Company. Train -1 and 2 design production capacity is 350MMscf/d for each train. Current production is well below the design capacity. COMPANY requires inspection assessment and rehabilitation of the FACILITIES. CONTRACTOR will define, through Work Orders, the scope of work, followed by engineering, procurement and construction management services to rehabilitate the FACILITIES. The FACILITIES' rehabilitation will be executed in accordance with COMPANY's MASTER PLAN. COMPANY MASTER PLAN shows the requirement to bring Train 2 into full design capacity and thereafter rehabilitate Train 1. COMPANY has identified Priority Works that requires immediate attention. These works should be performed concurrently with Train-2 work. The FACILITIES includes three LPG production units of which one unit is out of operation. Rehabilitation Phase will result in reduced flaring, with the objective of returning assets to operation in a safe manner. Later, rejuvenation will address FACILITIES’ life extension and return to nameplate capacity. Two Contracts have been awarded to CONTRACTOR, one for In-Country Works and the other for Out-of-Country Works.

ERECTION

12.1

Transporting and Preparation

Rev. 03A Agreement No. SIGUP-12-064 Page 19 / 21

When transporting fabricated materials, care shall be taken so as not to deform or damage them. Fabricated steel found bent or twisted shall be duly corrected prior to erection. Fabricated materials shall not be laid on the muddy or corrosive ground directly during storage. Prior to erection, surfaces of structural steel in high strength bolt connection to come in contact with each other shall be cleaned of any loose mill scale, dust, oil, paint, or other foreign matter.

12.2

Erection To safeguard against gusts, earthquakes, or other sudden loads during erection, the steel shall be supported with wire rope and turnbuckles. Temporary bolts and welds for erection shall be of sufficient strength to withstand erection loads. Unless otherwise specified in the drawings, all temporary bolts in welded connections need not be removed. Those bolts shall be finished bolts. Structures shall be aligned and inspected. Aligned position shall be maintained accurately during bolting and welding work. All anchor bolts at column bases shall be tightened immediately after alignment of structures. Ladders, lugs and hooks welded to structures for the purpose of erection and safety in accordance with the drawings shall not be removed, unless otherwise specified or requested.

The Manufacturer/Supplier shall be responsible for: Setting out of the works and for accurately positioning, plumbing, lining and levelling of all steelwork in accordance with the drawing., Unless otherwise specified, tolerances for erection of structural steelwork shall be: ♦

Levelling +/- 3 mm (1/8 in).

♦

Alignment and plumb +/- 3 mm (1/8 in)

The adequacy and installation of any temporary bracing or guy cables required to counteract loadings imposed during erection. This responsibility shall also extend to temporary bracing required to ensure safe and stable conditions of partially completed structural assemblies. The structure shall be plumbed, levelled, and braced before any final bolted or welded connections are made.

12.3

Correction of Errors Fit up bolts and drift pins shall not be used to bring improperly fabricated members and parts into place (springing). Drift pins shall not be driven with such a force as to injure adjacent metal areas. When approved by the Contractor, standard holes may be enlarged by 1 mm (1/16 in) when necessary to make connections resulting from minor misfit. Holes in connections that misfit by more than 1 mm (1/16 in) shall be corrected unless otherwise approved. Enlargement of holes shall be made by reaming or drilling only. Flame cutting, burning, gouging, chipping, or drift punching shall not be permitted. No packing, shimming, filling, or wedging shall be permitted to correct faulty work unless otherwise approved by the Contractor. One filler plate up to 3 mm (1/8 in) thickness may be used as required in spaces between members to be bolted.

12.4

Coating Repairs All erection damage to hot-dip galvanized or to shop-applied paint coatings shall be repaired in accordance with the project’s specifications.
