Multi-purpose sleeve for tieback connector |
摘要 |
A tieback connector connects a riser between a subsea wellhead housing and a floating platform. The tieback connector has a tubular body that stabs into and seals with a casing hanger. A latch member on the tieback connector engages a locking profile to secure the tieback connector to the wellhead housing. A sleeve is slidably carried on the tubular body between a running-in position and a set position. The lower end of the sleeve lands on an upper rim of the casing hanger prior to the seal engaging the seal surface. Continued downward movement of the tubular body relative to the sleeve causes the seal to engage the seal surface and the sleeve to move to the set position. The sleeve has upper end that engages a lower end of the latch member to limit any upward movement of the casing hanger in the wellhead housing. |
