Effect of earthquake directional uncertainty on the seismic response of jacket-type offshore platform
In the seismic risk assessment of structures, two main random variables are involved, namely the vulnerability of the structure and the seismic action. The aim of the study presented here is to analyze the seismic behavior of the jacket-type offshore platforms as an expensive and vital structure. Furthermore, the influence of the incidence angle of the seismic action is also investigated by usi...
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 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 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 کاملEFFICIENT NUMERICAL DYNAMIC ANALYSIS OF TENSION LEG PLATFORMS UNDER SEA WAVE LOADS
However it is possible to use of numerical methods such as beta-Newmark in order to investigate the structural response behavior of the dynamic systems under random sea wave loads but because of necessity to analysis the offshore systems for extensive time to fatigue study it is important to use of simple stable methods for numerical integration. The modified Euler method (MEM) is a simple nume...
