  • Deep water TLP tether system
    Patent number: 6851894
    Abstract: A tether system include tethers each having an upper section (1) attached to a tension leg platform (TLP) (4), and each upper section has a large diameter so that the upper section (1) is positively bouyant. This buoyancy can be designed to compensate for the weight of the lower section (2) of each tether, so as to make the total buoyancy of each tether closer to neutral. The selection process for each section is driven by requirements for buoyancy, stiffness and external pressure resistance.
