Wake effects commonly exist in offshore wind farms, which will cause a 10–20% reduction of whole power production as well 5–15% increase fatigue loading on the turbine main structures. Obviously wake interaction between floating (FOWT) is more complicated, and needs careful assessment prerequisite for active control (AWC). The primary objective present research to investigate detail how inflow ...

Added mass and damping play a significant role in accurate prediction of floating wind turbine (FWT) motions, especially near the resonance frequencies. This paper investigates still-water hydrodynamic characteristics semi-submersible FWT around natural periods surge, heave pitch motion. A higher-fidelity tool (Computational Fluid Dynamics, CFD) based on OpenFOAM is employed numerical computati...

Flexible riser is a class of flexible pipes which is used to connect subsea pipelines to floating offshore installations, such as FPSOs (floating production/storage/off-loading unit) and SS (semisubmersible) platforms, in oil and gas production. Flexible risers are multilayered pipes typically comprising an inner flexible metal carcass surrounded by polymer layers and spiral wound steel ligamen...
