Abstract
A sleeve, suitable for temporary use on a tendon for a tension leg platform (TLP) equipped with a bottom tendon connector, covers selected portions of the tendon and bottom tendon connector so as to provide an outer surface having fewer and/or less pronounced discontinuities in the outer diameter of the assembly. This improves the handling characteristics of the assembly in pipe tensioning devices and the like. The sleeve may be in form of split halves which may be held together around the selected portion of the tendon by band straps. The sleeve may be removed subsea by cutting the band straps using an ROV. In certain embodiments, the sleeve comprises an open frame arrangement of contoured segments held in a spaced-apart configuration by bolt-together or hinged clamps. The sleeve may provide an annular space between the tendon and the sleeve which may be used to house a flotation device.
