Harris Pye Completes West Pegasus Contract
The Harris Pye Group has successfully completed a USD 4.3 million contract for work on Seadrill‘s West Pegasus ultra-deepwater semi-submersible rig. The six-week contract involved a workforce of 115 working initially on column blisters, and extended work. Harris Pye technical director Chris David: “At the outset we were to be involved solely with the fitting of four 72t column blisters on the rig legs to increase the water plane area of the rig and improve its metacentric height (GM).”
He continues: “Once on board it became obvious there was more work to be undertaken to equip West Pegasus for its five-year contract with Pemex, and our role was greatly extended.”
Project Team
The column blister contract encompassed the supply of a complete project team; and the design, fabrication and installation of all miscellaneous steelwork to assist in the lifting and fixing of the blisters.
“The lifting operation involved some highly innovative solutions,” says Chris David. Supplies for the contract included 4,000 m of scaffolding; painting repairs; all tools, equipment and consumables including gases; and a substantial amount of freight. Full documentation on quality control and quality assurance was also included in the contract.
Extended Role
Chris David explains: “Our extended role on board the West Pegasus encompassed the supply of tow bridle tuggers and working platforms; installation of transformers and associated power supplies; modifications to lighting circuits; mudroom stairway installation; new shaker room platform; sea water pipework to RO system; helideck and accommodation walkways; helideck lighting; welding the point ring main; work in the mud treatment room; and installation of miscellaneous lighting and cabling. Once on board the strength of our multi-talented team was fully maximised on a variety of tasks.”
