Tahoe subsea completion -- A successful application of existing and new technologies
The Tahoe subsea satellite tieback (VK783) demonstrates how existing and new subsea technologies can be combined to achieve a cost effective yet technically significant subsea project. A used Green Canyon 29 subsea Xmas tree was refurbished and modified to implement more recent first-end layaway techniques for both the flowline and umbilical. The diverless completion was made in 1,500 ft. of water and tied back approximately 12 miles to a platform in 275 feet of water (Main Pass 252). The flowline system consisted of dual nominal 4-in. lines comprising both flexible and rigid pipes. The control system was multiplexed electrohydraulic with signal-on power umbilical transmission. Both downhole and Xmas tree temperature and pressure measurements were employed. The techniques used in the Tahoe subsea system can be applied to other projects to help improve cost, schedule, and reliability of subsea tiebacks.
