  • Method and apparatus for erecting a marine structure
    Patent number: 5558468
    Abstract: The deck or superstructure for an offshore production platform is shifted from a loading facility onto a cargo vessel that includes a large-area lifting assembly. The vessel transports the superstructure to a previously-installed substructure. On site, the elevator assembly raises the superstructure above the top of the substructure jacket, aligns the superstructure with the substructure and then mates the two together by lowering the elevator assembly. The elevator assembly is designed to break away very rapidly from the superstructure to compensate for vessel rebound when the mass of the superstructure is accepted by the substructure.
