    Largest deck in the Gulf leaves McDermott yard

    Yard News // March 14, 2003
    After 23 months of construction of the largest deck ever built in the Arabian Gulf, project staff at J Ray McDermott's Jebel Ali fabrication facility bid farewell to the 12,125-ton Amenam Kpono AMP1 production platform as it embarked for Nigeria last month. Traveling a distance of some 7,360 miles, the platform was expected to take 28 days to arrive.

    The integrated deck was constructed for Elf Petroleum Nigeria Ltd. under a contract to a consortium led by Saibos CML, for the Amenam/Kpono field, located approximately 19 miles off the coast of Nigeria - in waters 131ft deep.

    "Amenam was a turnkey - Engineer, Procure, Construct, Install (EPCI) undertaking by the project consortium - J Ray McDermott's involvement was fabrication of the AMP1 jacket and deck," said Kurt Nelson, vice president and general manager of J. Ray McDermott, Eastern Hemisphere operations.

    "The construction of the AMP1 production platform was fast-track, and there are few yards in the world capable of fabricating a deck of such magnitude, within such a time frame," explained Nelson.

    "We designed the project execution plan to comply with the client's schedule and to deliver with uncompromised commitment to safety and quality, so that the deck could be pre-commissioned before it left our yard."

    Throughout the entire project several million man-hours were spent constructing the deck, with only one minor lost time incident - a considerable success - given the nature and complexity of the project.

    "The completion of this size facility for export to West Africa is certainly an achievement. Our skilled workforce and specialists have produced first class, quality work and I am extremely proud of their contribution to the project's success," said Nelson.

    The AMP1 deck, constructed as a single piece, comprises three decks - a weather deck, mezzanine deck and main deck - with an additional, smaller cellar deck and an integrated four level building. Built as separate deck levels this lead to a series of impressive lifts when the levels - ranging from 1,000 to 1,500 tons each - were stacked one on top of the other, a procedure adopted to maximize productivity by enabling simultaneous work on all three decks.

    The associated jacket with appurtenances of 3,700 tons was also fabricated at J Ray's Jebel Ali yard.

    The design production and processing capacity of the facility is 130,000 barrels of oil per day, with gas and water injection per day of 15 million m3 and 12,500 m3 respectively.
