The offshore floating wind turbine system is a key piece of equipment for harvesting energy from the ocean field. However, structural safety analysis and design such largely require suitable platform to accurately obtain dynamic characteristics. In present study, an attempt was made investigate responses proposed 5-MW WindStar multi-column tension-leg-platform (TLP) under different environment ...

The studies on floating offshore wind turbines (FOWTs) have been increasing over recent decades due to the growing interest in renewable energy. present paper proposes a barge platform with four moonpools support Technical University of Denmark 10 MW turbine for designed water depth 60 m. A 4 × 2 mooring system eight lines is also proposed platform. main dimensions are optimally selected respec...

The offshore wind industry, which aims to reduce the operational costs, usually achieved through learning curves and supply chain improvements, has seen drastic cost increase over the last five years. In order to sustain the competitiveness of the offshore wind industry against other renewable energy sources, the cost of offshore wind needs to come down to today’s onshore cost. This cost reduct...

An experimental study was conducted to investigate the dynamic wind loads acting on a wind turbine model sited in atmospheric boundary layer winds. The experimental studies are conducted in a large-scale Aerodynamic/Atmospheric Boundary Layer (AABL) Wind Tunnel available at Iowa State University. A three-blade Horizontal Axial Wind Turbine (HAWT) model was placed in atmospheric boundary layer w...

This study predicted the motion response and power performance of a floating wind turbine system equipped with semisubmersible Taida platform, an IEA 15 MW turbine, 3 × 2 mooring design in Hsinchu offshore area Taiwan Strait. The hydrodynamic properties were calculated using ANSYS-AQWA STAR-CCM+. equations solved by OrcaFlex to obtain generator power, as well dynamics aerodynamics turbine. wave...

Wind energy is undergoing expansion, and it is bound to grow to a commercial/consumer level in the decades to come. This growth has materialized in the form of large-scale wind farms, wind energy cooperatives, wind turbines owned by individual investors, and multinational exploration of remote sites and offshore locations. Despite the increasing rated capacity of wind turbines, operation and ma...

Floating offshore wind turbines are a promising technology for addressing energy needs by utilizing resources offshore. The current state of the art is based on heavy, expensive platforms to survive ocean environment. Typical design techniques do not involve optimization because computationally time domain solvers used model motions and loads in However, this uses an efficient frequency solver ...
