SUBSEA WELL APPARATUS

摘要

There is disclosed subsea well apparatus having a wellhead member body adapted to be lowered into and latched within the bore of a conductor by means of split locking (LR) and ratchet rings (25) carried by the body in response to the weight of the casing suspended from the body. The locking ring (LR) has locking teeth (14) engageable with locking grooves (14A) in the bore, and the ratchet ring (25) has ratchet teeth engageable ratchet grooves (29) within the locking ring. Upper and lower coaxial downwardly and inwardly extending wedge surfaces are tightly engaged as the body is latched within the conductor.
