... A truss Spar with direct vertical access merit has been designed and installed in ultra-deep water of Gulf of Mexico for a few years. This paper intends to carry out a comparative study of a Paired-Column Semi-submersible (PC-Semi) platform with the same topsides payloads, TTRs tensions, Ram...

... Vortex Induced Motions (VIM) of a Spar platform have significant impact on the performance of mooring and riser systems in terms of both strength integrity and fatigue, especially when the platform is located in high current speed environment. With A/D curves obtained from VIM model tests or CFD...

... system in time domain. FAST was developed by the National Renewable Energy Laboratory (NREL) for computing the wind loads on a wind turbine. A 5MW wind turbine installed on the top of a classical Spar (Hywind-OC3 Spar) is employed to demonstrate the simulation. The numerical results derived in this study...
