  • Mooring and supporting apparatus and methods for a guyed marine structure
    Patent number: 4417831
    Abstract: A method and apparatus for supporting a deep water guyed marine structure has a foundation which uses a system of piles connected to the marine structure only at a top portion thereof. The marine structure further has a mooring system which employs pairs of transversely, closely spaced guy lines connected to clump weights and further pairs of transversely, closely spaced guy lines connected from the clump weights to an anchor system. The marine structure mooring system can further provide a vessel mooring system in order to provide adequate control of the vessels during on and off loading of the marine structure and further to prevent fouling of the marine structure mooring system.
