A single leg tension leg platform is a semi-submersible structure moored at a deep water site by hybrid mooring consisting of a single tension leg or cluster of tendons attached to a central column and, optionally, a conventional spread mooring system. The central column is surrounded by peripheral stability buoyant columns symmetrically arranged and typically in number from about 3 to 8. All the vertical tendons are located in a tight cluster at the center of the platform. This means that the tendons no longer effectively restrain pitch/roll or yaw motion. The role of the tendon cluster is essentially the direct, stiff elastic restraint of heave and compliant restraint of horizontal offset. Pitch/roll response is controlled primarily by careful distribution of peripheral buoyancy and detuning.
