ABSTRACT:
The present invention provides methods and apparatus for tension compensation in the tension legs used to moor a floating platform to the sea floor. The apparatus includes one or more hydraulic jacks, each having a cylinder coupled through a load block to a tension leg, and having a piston cooperating with a load block plug coupled to the floating platform. An accumulator supplies hydraulic fluid to the jacks to compensatingly adjust the relative position of the piston and cylinder to selectively maintain the tension loading of the tension leg.
