Resonance of a tension leg platform exited by third-harmonic force in nonlinear regular waves.
The resonance of a floating tension leg platform (TLP) excited by the third-harmonic force of a regular wave is investigated based on fully nonlinear theory with a higher order boundary element method (BEM). The total wave elevation and the total velocity potential are separated into two parts, based on the incoming wave from infinity and the disturbed potential by the body. A numerical radiati...
متن کاملStochast!c response of a tension leg platform to viscous and potential drift forces
The wave drift forces on tension leg platforms (TLP) are contributed by secondorder potential and viscous wave load effects, the fluctuations in wave surface elevation and the influence of platform displaced position on the wave excitation. These forces are expressed in terms of in phase and out of phase drift forces. In this study, computationally efficient time domain and frequency domain bas...
متن کاملInfluence of Tether Length in the Response Behavior of Square Tension Leg Platform in Regular Waves
The tension leg platform (TLP) is a vertically moored structure with excess buoyancy. The TLP is regarded as moored structure in horizontal plan, while inherit stiffness of fixed platform in vertical plane. In this paper, a numerical study using modified Morison equation was carried out in the time domain to investigate the influence of nonlinearities due to hydrodynamic forces and the coupling...
متن کاملTension Leg Platform Design Optimization for Vortex Induced Vibration
Tension Leg Platform design is a challenging and popular area of research in the offshore oil industry. In order to compete in the International Student Offshore Design Competition (ISODC), a Tension Leg Platform (TLP) was designed. Our TLP design addresses five fundamental areas of technical competency (General Arrangement and Overall Hull/System Design, Weight, Buoyancy and Stability, Global ...
متن کاملIndividual Blade Pitch Control of a Floating Offshore Wind Turbine on a Tension Leg Platform
A disturbance accommodating controller (DAC) to reject wind speed perturbations is applied on a 5MW wind turbine mounted on a tension leg platform (TLP). Multi-blade coordinate (MBC) transformation is used to address the periodicity of the floating wind turbine system. A method to apply DAC after applying MBC transformation is developed and several implementation options are presented. Simulati...
