Abstract

Tension leg platform (TLP) is suitable for deep water oil and gas exploration. The nonlinear dynamic response analysis of TLP under random sea wave load is necessary for determining the maximum deformations and stresses. Accurate and reliable responses are needed for optimum design and control of the structure. In this project nonlinear dynamic analysis of TLP is carried out in the frequency domain. The time history of random wave is generated based on Pierson-Moskowitz spectrum and acts on the structure in arbitrary direction. The hydrodynamic forces are calculated using the modified Morison's equation according to Airy's linear wave theory. The motion spectrum density of displacements is calculated from linear responses. The focus of the paper is on the comprehensive interpretation of the responses of the structure related to wave excitation and structural characteristics. A case study is investigated and numerical results are discussed.
