... adaptable to water depth, however, suffers larger seakeeping motions in waves. In order to improve the seakeeping performance of the barge foundation for offshore wind turbines, the present work proposes a concept of Air-cushion Supported Floating Platform (ASFP), and integrates the air cushion into barge...

... ABSTRACT The support structure of offshore wind turbines is working in harsh ocean environments, where uncertainties exist and affect the performance of the whole system. This work presents an efficient methodology for the Reliability Based Design Optimization (RBDO) of the support structure...

... ABSTRACT Currently, the development of renewable energy has become a trend with the increasing demand for energy. Wind energy, as a renewable source of energy, is also getting more attention. Increasing effort is devoted to developing floating offshore wind turbines in deep water...

... ABSTRACT Wind power generation is gradually expanding from land to sea. In floating offshore wind turbine, the position of floater is maintained by the mooring line, and it is difficult to predict the behavior by the combined action of wind and wave forces. To create optimal design conditions...

... Abstract The tripod foundation has been used as a popular support structure for offshore wind turbine (OWT). Typically, only deterministic computational model is considered by applying relevant standards and codes during the preliminary design of the foundations of OWT. However, uncertain...

... Abstract In the offshore environment, aerodynamic and hydrodynamic loads induced by wind, wave and current are directly or indirectly applied to the foundations for offshore wind turbines (OWTs). To avoid resonance, the first frequency of the OWT system must keep away from the frequencies...

... Abstract With the development of the offshore wind turbine technology, the offshore wind turbine is going to deeper waters, and the scale of the offshore wind turbine is becoming larger, in which case the numerical computation of aerodynamic performances of large-scale floating offshore wind...

... Abstract In this paper, three typical floating offshore wind turbines (FOWTs) were studied, with the generic 5MW wind turbine. The dynamic responses of three FOWTs are calculated in both frequency and time domain in operational and survival case under the same environmental conditions. During...

... Static and Dynamic Analysis Modeling for offshore Wind Turbine Foundation Structures Hongwang Ma and Longzhu Chen School of Naval Architecture, Ocean and Civil Engineering Shanghai JiaoTong University, Shanghai, China ABSTRACT In recent years, offshore wind farm in the world has been rapid...

... ABSTRACT: Based on the 5MW offshore wind turbine model developed by National Renewable Energy Laboratory (NREL), two new conceptual offshore wind turbine floating platforms with combined Tension legs- Mooring lines system were proposed in this paper. Taking the coupled dynamic responses...

... and proper environment. A wind power generation can be classified into two groups, onshore wind turbines and offshore wind turbines, and offshore wind turbines can be sorted by the fixed type and the floating type wind turbines. Fixed type wind turbine systems are set up at relatively low depth of water near...
