| Popis: | The effect of increasing water depth on the performance of deep water tendons of tension leg platforms (TLP) is examined. Equations to determine limts on water depths for tendon systems based on strength and hydrostatic collapse requirements are presented. Relations between tendon tensions and reactions on a TLP hull are derived. Conditions for which neutrally buoyant tendons can be utilized are presented. For very deep water, the limiting diameter-to-thickness ratio (\ID\N/\It\N) is presented for different tendon variables. For a water depth of 5,000 feet, the \ID\N/\It\N ratio is limtied to about fifteen due to hydrostatic collapse constraints. Composite tendons can provide reduced pretension, improved restoring force, and reduced drag forces. |
