Recently, various types of tension leg platform (hereinafter called “TLP”) have been proposed, designed, and constructed for deep sea oil drilling and production platforms. This paper first presents a basic concept of a TLP with a mechanical damping system (hydraulic damper). Next, the basic planning on a prototype model of TLP with a mechanical damping system is briefly described. Finally, the results of an in-laboratory dynamic loading test, which was performed to verify the performance of hydraulic damper selected an optimum system, are also introduced.
