Development and application of a Shear Ram Tubing-Head System for increased offshore platform safety
Concurrent drilling and production operations on offshore platforms increase the potential for blowouts and subsequent fires. Present wellhead and christmas tree designs address the potential for production equipment to resist flame impingement for limited exposure periods, but new technology is required to eliminate the source feeding the flame. Den Norske Stats Oljeselskap A/S (Statoil) has recently proposed a concept incorporating a BOP shear ram system permanently installed in the wellhead in order to shear and seal the tubing in the event of emergency. Gray Tool Company and Hydril have combined their expertise in wellhead equipment and blowout prevention systems to provide a tandem hanger system incorporating metal-tometal sealing and tubular support, tubular shearing, fish retrieval, and tie-back re-entry capability. This report details the design, manufacture, installation and full scale laboratory testing which successfully confirmed the ability of the Shear Ram Tubing Head system to suspend, tie back, shear and seal 7 in., 32 lb./ft. N-80 tubing at 5.000 psi MSP.
