  • Method of and apparatus for the anchoring of drilling and production platforms on a structure sunk on a sea bottom
    Patent number: 4069680
    Abstract: A system for anchoring drilling or production platforms upon a plurality of posts anchored in the sea bottom or on an artificial island comprises a cylinder structure formed at the top of each of the posts and a plunger depending from a semi-submersible platform adapted to be received with clearance within each of the cylinders. The platform is provided with sand bunkers adjacent the respective plungers and with releasable closures which open upon positioning of the platform above the posts to cause granular material to flow into the cylinder around the respective plungers, thereby cushioning the engagement of the platform by the posts.
