Abstract

An improved detachable mooring system is disclosed of the kind including a rotatable turret mounted on the vessel and a buoyant spider buoy, secured by mooring legs to the sea floor, which may be selectively connected by means of a hydraulic connector to the bottom of the turret. One improvement relates to apparatus for establishing pre-load tension between a collet flange hub of the spider buoy and a hydraulic powered connector at the bottom of the turret. Another improvement relates to apparatus for remotely sensing the level of pre-load tension in the connector. Another improvement relates to a self-aligning support arrangement for supporting the collet connector to the bottom of the turret. Another improvement relates to an axial load bearing arrangement for supporting the turret with respect to the vessel.
