STRUCTURAL MOVEMENT TO MOVE FLOATING PLATFORM AT GREAT DEPTH AND PROCEDURE IN ESTABLISHING THE MOVEMENT

摘要

A method for securely mooring a floating tension leg platform (20) to an anchoring base template (36). The method involves swinging an end of a neutrally buoyant, one piece tendon (46) which has an enlarged connector (62) downwardly into position adjacent an anchoring receptacle (42), pulling the enlarged connector through a side-entry opening (122) in the receptacle, lifting the tendon to seat the enlarged connector in a load ring (120) of the receptacle, adjusting the effective length of the tendon to place it in tension and repeating these steps for each of the mooring tendons. A one-piece, thin-walled, neutrally buoyant tendon (46) is also disclosed.
