  • Publication number: 20140205383
    Abstract: The invention relates generally to a method for supporting non-buoyant offshore drilling units that are anchored to the sea floor and are subject to heavy lateral loads. Specifically, tension tendons are attached to piled foundations to prevent jack-ups from being overturned by the loads. Tension can also be applied to the tendons to provide additional hold down forces to the offshore units.
