Development of Tension Leg Platform with Mechanical Damping System

Basic Planning of TLP and Performance Test Results of Hydraulic Damper

Abstract

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.
