Conceptual Discussion on Free Vibration Analysis of Tension Leg Platforms Mohammad Reza Tabeshpour Center of Excellence in Hydrodynamics and Dynamics of Marine Vehicles, Mechanical Engineering Department, Sharif University of Technology, Tehran, Iran tabeshpour@sharif.edu Abstract Tension leg platforms are used for oil exploitation in deep water. The accurate and reliable responses are needed for optimum design and control of the structure. Free vibration analysis gives us a deep view of structural response and the judgment on coupling effects between degrees of freedom. In this paper the nonlinear dynamic analysis of TLP is carried out. The power spectral densities (PSDs) of responses are calculated from nonlinear responses. A computer program has been developed capable of solving differential equation of motion of TLP under various types of excitations. The focus of the paper is on the conceptual discussion of the structural behavior and responses of the structure related to initial arbitrary conditions. As an example a case study is investigated and numerical results are discussed.
