Overall dynamic characteristics of tension leg platforms
In TLP (tension leg platform) motion analysis, the problem is usually simplified by idealizing the tethers as weightless springs. While this approximation appears to be generally adequate for shallow waters, the relative tether/platform weight ratio increases very rapidly as the water depth increases, thus making it necessary to treat the TLP as a continuous system rather than as a rigid body with only six degrees of freedom. The purpose of this paper is to examine the variation of the overall dynamic response characteristics of a TLP as a function of the water depth, with particular emphasis on such important parameters as the tether/platform weight ratio, the periods of the ''principal modes'' (i.e., heave, pitch, roll, surge, sway and yaw) and the shapes and periods of the ''secondary modes''.
