Shell and Esso's Central Cormorant field project is one of the most innovative endeavors in offshore oil field history. Although most of the attention has centered around Shell Expro's Underwater Manifold Center (UMC), the field also will include production from five diverless through flow line (TFL) satellite trees, which were designed, fabricated, and tested by Vetco Offshore. The first satellite tree (P1) was brought on stream in January 1981 and has produced continuously to the South Cormorant platform. The remaining four trees were assembled between 1981 and 1983. These deepwater trees, representing a technically advanced design, will be used to produce from formations at a considerable distance from the UMC. The basic design criteria for the trees include diverless operation, dual hydraulically controlled master valves, 5,000-psi working pressure, chemical injection capability, 200 F produced fluid temperature, H/sub 2/S-CO/sub 2/ service, metal-to-metal seals throughout, and TFL well maintenance and service capability.
