Title: Seafloor manifold center installed

The Shell/Esso Underwater Manifold Center (UMC), designed and tested as a diverless production facility, is a significant step toward really deep water oil and gas production. In May 1982, the 2100 metric ton unit was towed 645 miles from its Dutch fabrication yard and precisely emplaced in 500 ft water in the Cormorant field in only 6 days. When fully installed with all of its wells drilled and testing completed, the UMC will have cost an estimated $700 million. During its anticipated 25 yr operating life, the UMC is expected to produce ca 110 million bbl from the central Cormorant area. Design and operational criteria are described.
