The use of offshore wind farms has been growing in recent years, as steadier and higher wind speeds can be generally found over water compared to land. Moreover, as human activities tend to complicate the construction of land wind farms, offshore locations, which can be found more easily near densely populated areas, can be seen as an attractive choice. However, the cost of an offshore wind far...

In this paper, the fluid–structure interaction of floating offshore wind turbine (FOWT) platforms under complex ocean conditions is investigated using OpenFOAM and in-house developed models. Two types FOWT platform, i.e., a semi-submersible platform barge are studied for their dynamic responses to either wave or current. The results reveal that exhibits larger cross-flow motion lock-in phenomen...

The Vertical Axis Wind Turbine (VAWT) is a promising technology for energy harvesting in complex environments, including Floating Offshore Turbines (FOWT), which experience aerodynamic complexity due to the platform motion. typical large-scale of FOWTs makes troposkien design, unique VAWT configuration suitable such applications. In this paper, we propose an experimental and numerical study on ...

The construction, operation, and removal of offshore wind power facilities have the potential to increase the levels of noise in the surrounding waters. Increased shipping noise can be associated with all phases of the life cycle of wind farms. Pile driving during platform construction can be short-lived but can introduce very high intensity pulses into the ocean. Operational noise, while at a ...

Offshore wind farms with high installed capacities and located further from the shore are starting to be built by northern European countries. Furthermore, it is expected that by 2020, several dozens of large offshore wind farms will be built in the Baltic, Irish and North seas. These wind farms will be constituted of a considerable number of turbines packed together. Due to shadowing effects b...

Cost-effective, predictive and proactive maintenance of wind turbines assumes more importance with the increasing number of installed wind farms in more remote location (offshore). A well-known method for assessing impeding problems is to use current sensors installed within the wind turbine generator. This paper describes then an approach based on the generator stator current data collection a...

This study aims to develop dynamic co-simulation and control for analyzing the IEA 15 MW semi-submersible floating wind turbine under Taiwan offshore-wind-farm conditions of wave. The is mounted on a UMaine VolturnUS-S reference platform with mooring system designed water depth 70 m, in this study. combines software SIMPACK, MATLAB/SIMULINK, AeroDyn, HydroDyn, WAMIT, MAP++ achieve complex simul...

In order to be economically competitive, various control systems are used in Wind turbine. These systems makes the wind turbine to work efficiently and produce maximum output at different speed. In this paper an adaptive control based on radial-basis function neural network are used for different operation of variable speed wind turbine including torque control at lower speed, pitch control at ...

Physical model tests with the scale of 1:36 are carried out in the Near-Shore Wave Basin (NSWB) at Tainan Hydraulics Laboratory (THL) with the jacket-type offshore wind turbine foundation (jacket-type foundation) and the combination of hard or soft scour protection in the test area. Scouring around the jacket-type foundation exposed to wave and current was conducted in the NSWB with a mobile be...
