CiTECH have been awarded the order from Mustang Engineering for three CiBAS C45 WHRU for the Tahiti Platform to provide heat to the on-board Oil and Gas Processing System. The CiBAS units are designed to be cold casing and run dry, the units are specified to recoup at a combined flow rate of 328,284kg/hr a total thermal duty of 42,600kwth through a Water System recovering heat from three Solar Titan 130 Gas Turbine running in a two duty one standby regime.
To save space on the platform the units have modified to allow them to operate inverted with the exhaust gas from the turbines entering through the top of the unit and exhausting through the bottom, they are mounted onto an extension platform attached to the first deck.
Tahiti is located in the deep-water US Gulf of Mexico, in a water depth of approximately 4,200ft (1,280m). The field was refined from two subsea drill centres near the two Tahiti appraisal wells in Green Canyon blocks 596 and 640. They were produced into a floating production facility supported by a truss spar. Then this turned into the first spar with no drilling capability and no surface wellheads.
