Alliance Engineering awarded detailed topsides engineering and design for Williams Partners' Gulfstar One, Tubular Bells Field

HOUSTON, January 11, 2012 -Wood Group's Alliance Engineering has been awarded the detailed engineering and design of the topside facilities and deck for Williams Partners' Gulfstar FPS™ spar production platform. This wet-tree

platform will be installed in block 768 of the Gulf of Mexico's Mississippi Canyon area to produce oil and gas from the Tubular Bells field, which is owned by Hess Corporation (Operator) and Chevron U.S.A. Inc.

The Gulfstar spar platform will be located in 4,300 feet of water and designed to process 60,000 barrels of oil per day and 200 MMscf of gas per day. The single- lift topsides will have three deck levels and include processing equipment, seawater injection equipment, utilities, an accommodation building with helideck, and pumping and compression equipment to export the treated oil and gas through departing pipelines. The completed deck will weigh approximately 7,000 short tons. Initial production is scheduled to commence in 2014.

"Alliance has been working with Williams Partners to develop their standard Gulfstar floating production system concept (FPS)," said Edmund Lunde, president of Alliance. "With concept development and FEED completed, we are pleased to continue working with Williams Partners on the detailed design of their first Gulfstar FPS. We are confident Williams, Hess and Chevron will benefit from our focus, skill, and experience in developing the Tubular Bells topsides."
