Appl. No.:

09/962991

Inventors:

Jerry K. Rhodes - Conroe TX
Jason R. Jackson - Houston TX

Assignee:

ABB Vetco Gray Inc. - Houston TX

International Classification:

E02D 554

Abstract:

A bottom connector for the tendon of a tension leg platform uses a latch ring with an outer profile to engage a mating profile in a receptacle on the sea floor. The latch ring moves radially within a housing, relative to the receptacle, between an engaged position and a retracted position. The latch ring engages the receptacle by lowering the connector into the receptacle below the mating profile and then lifting it until the latch ring locks into the receptacle. The latch ring disengages the receptacle by lowering the connector beyond a recess located below the mating profile and then lifting the connector out of the receptacle. As the connector is lifted above the recess, a retaining ring is actuated by the recess to retain the latch ring in its retracted position.
