Based on the review of the pattern development course and performance on TLPs, some optimization principles are submitted such as compact arrangement of hull, extended mooring, minimum-offshore-surface, etc. And then a new-style TLP is put forward which is conceptually designed to be separated, self-balance, minimum-offshore-surface and extended moored (SSME). The purpose is to hold the Hydrostatic Stiffness while reducing the environment loads acting on the platform, decouple surge and heave of TLP, level off the tension in tendon, increase the effect of mooring system and improve the performance of platform in severe sea state. The heave of hull can be improved by adding heave plate to the bottom of hull. Then the concept design process of SSME TLP is presented combined with an example.
