Analysis of difference-frequency wave loads and quadratic transfer functions on a restrained semi-submersible floating wind turbine

Damping Wind and Wave Loads on a Floating Wind Turbine

Offshore wind energy capitalizes on the higher and less turbulent wind speeds at sea. To enable deployment of wind turbines in deep-water locations, structures are being explored, where wind turbines are placed on a floating platform. This combined structure presents a new control problem, due to the partly unconstrained movement of the platform and ocean wave excitation. If this additional com...

Wind-wave induced dynamic response analysis for motions and mooring loads of a spar-type offshore floating wind turbine

Due to the energy crisis and the environmental issues like pollution and global warming, the exploration for renewable and clean energies becomes crucial. The offshore floating wind turbines (OFWTs) draw a great deal of attention recently as a means to exploit the steadier and stronger wind resources available in deep water seas. This paper studies the hydrodynamic characteristics of a spar-typ...

Integrated System Design for a Large Wind Turbine Supported on a Moored Semi-Submersible Platform

Over the past few decades, wind energy has emerged as an alternative to conventional power generation that is economical, environmentally friendly and, importantly, renewable. Specifically, offshore wind energy is being considered by a number of countries to harness the stronger and more consistent wind resource compared to that over land. To meet the projected “20% energy from wind by 2030” sc...
