This article focuses on a Hardware-In-the-Loop application developed from the advanced energy field project LIFES50+. The aim is to replicate, inside a wind gallery test facility, the combined effect of aerodynamic and hydrodynamic loads on a floating wind turbine model for offshore energy production, using a force controlled robotic device, emulating floating substructure’s behaviour. In addit...

In this study, an unsteady aerodynamic simulation is performed to realize the influences of platform surge motion on the aerodynamic performance of a high capacity offshore floating wind turbine. A dynamic model with pitch angle control system is utilized to propose a more realistic model of wind turbine and also achieve the rated condition of the rotor. The transient effect of platform surge m...

We develop a numerical method for simulating coupled interactions of complex floating structures with large-scale ocean waves and atmospheric turbulence. We employ an efficient large-scale model to develop offshore wind and wave environmental conditions, which are then incorporated into a high resolution two-phase flow solver with fluid-structure interaction (FSI). The large-scale wind-wave int...

This paper presents a literature review of the dynamics offshore floating wind turbine platforms. When moving further offshore, there is an increase in capacity power. Generating power from renewable resources enhanced through extraction energy deep-water resource. Mounting on platform that not stable brings another difficulty to modeling. There need introduce platforms are more effective captu...

Offshore wind turbines have been installed in increasing water depths over the last years. Support structures with monopile or gravity based foundation could successfully be used for all realized offshore-projects, but the trend of increasing water depths reached a level that makes application of those relatively simple types of support structures inappropriate. New concepts like tripods or lat...

Structural optimization of offshore wind turbine structures has become an important issue in the past years due to the noticeable developments in offshore wind industry. However, considering the offshore wind turbines’ size and environment, this task is outstandingly difficult. To overcome this barrier, in this paper, a metaheuristic algorithm called Enhanced Colliding Bodies Optimization...

Many industries identify condition monitoring as a major opportunity to reduce maintenance costs and increase equipment availability. This is also the case for the fast emerging offshore wind turbine technology. However, when considering offshore wind turbine farms, implementation of condition monitoring also introduces a significant capital investment cost. Moreover, condition monitoring syste...

Taiwan is located on the Pacific seismic belt, and the soil conditions of Taiwan’s offshore wind farms are softer than those in Europe. To ensure safety and stability of the offshore wind turbine supporting structures, it is important to assess the offshore wind farms seismic forces reasonably. In this paper, the relevant seismic and geological data are obtained for Chang-Bin offshore wind farm...
