This paper concerns dynamics of a tension leg platform (TLP) under wind, wave, and current load effects. A parallel computation scheme for coupled analysis of TLP-tether system is utilized. The method encompasses the combined response of TLPs through coupled substructural systems involving the top platform and bottom tethers. The coupled platform-tether analysis of the example TLP suggests that the nonlinear effects introduced by the tether curvature, mass and varying tension are important, and these effects become more pronounced as the water depth increases. Use of conventional approach that involves several simplifications to evaluate the influence of tethers on the overall TLP response without considering the above nonlinear effects may provide inaccurate results, especially the TLP motions in the vertical plane. The parallel computation scheme presented here makes the combined analysis of TLP systems computationally efficient.
