Laying of transition pipe, tie-in and hook-up job of 18-inch HBPL with the existing HDD sections at four locations under ERPL Haldia

TRANSITION PIPE LAYING (>12 m length on both sides) of specified diameter: Laying of Owner-supplied pre-coated mild steel line pipes , including arranging all additional land/construction corridor, beyond Owner's ROW, required for Contractor's storage, fabrication, access for construction site, movement of construction equipment etc., receiving and taking over Owner-supplied materials, handling , transportation etc. from Owner's issue point to work site, stringing along Right of Way (ROW)/ pipeline corridor, providing labour , equipment and supply of other inputs & materials/ consumables necessary to perform and complete the work in all respects in accord ance with the instruction from EIC / Site Engineer. Transition Pipe laying upto 12 m length on both sides is included in the SOR ite m for Tie-In and Hook up.

Collecting any oil and/or oil water mix accumulated in the pit after evacuation of product from the old pipeline section & transport ing the same in oil tankers to the nearest IOCL installation without any spillage, complete in all respect & as per the directions o f EIC / Site Engineer.

PIPE RETRIEVAL- Retrieval of cross country mild steel pipeline section by excavation up to bottom level of pipe which is normally at 1.5 to 2 m depth, by cutting at every 10 to 12 meters by suitable safe method as approved by EIC / Site Engineer (pipe to be cut ne ar to old girth weld of pipe and at some places cutting may be required at lesser length as per site requirement), removal of pipes from trench, loading, unloading and transportation to owner's installation with all labours, vehicles, tools and tackles, equipment as directed by EIC / Site Engineer including backfilling of excavated trench with excavated earth along with additional appropriate quantity of soil (to be arranged by the contractor) after removal of pipe, compacting the backfilled earth and restoring to original level and condition. (pipe of 18"diameter)

TIE-IN & HOOK-UP- Carrying out tieing-in and hook-up of the installed HDD sections including laying of transition piping upto 12 m f or hook-up with existing Mainline on either side of HDD crossing including all excavation/ trenching in all kinds of soil including rock,transportation of coated pipe from owner's stackyard, cutting of pipe, pre-testing of pipe sections before hook-up, making fiel d bends out of pre-tested pipes (pipes shall be supplied by Owner) to match the site requirement, welding, carrying out 100% radiogr aphy, field joint coating, holiday detection, repair of damaged coating, backfilling and making through the pipeline etc. complete i n all respects as per specifications and directions of Engineer-in-Charge.

Coating Removal- Excavation up to bottom level of pipe which is normally at 1.5 to 2 m depth for lengths upto 30m, removing the coat ing, creating access for carrying out hot-tapping operation, applying the coating again after completion of Hot-Tapping Works and ba ckfilling the excavated trench with excavated earth along with additional appropriate quantity of soil (to be arranged by the contra ctor), compacting the backfilled earth and restoring to original level and condition with all labours, materials, tools and tackles, equipment etc. as directed by EIC / Site Engineer.
