This study establishes a multi-hazard probabilistic assessment framework for assessing the integrity of monopile offshore wind turbines (OWT) under stochastic coupled effect wind, wave and earthquake loading. The procedure deals with entire operational range inflow speed (i.e., 3–25 m/s), which probability failure excitations is found to be non-negligible. Numerical analysis performed by implem...

Abstract This paper explores the preliminary design of support structures for IEA Wind Task 37 reference wind farm at Borssele site III and IV. The study looks two different methods that might be used within larger system optimization ( i.e. lay-out, electrical systems, etc. ). first consists a scaling tool scales detailed according to rated power, water depth, hub height rotor diameter. second...

A commonly used material in offshore structures is S355 structural steel. For example, during the monopile fabrication process, pre-strained to different levels at depths through thickness. Therefore, influence of pre-straining on fatigue life and crack growth behaviour needs be examined considered for design assessment procedures. In present study, uniaxial tests have been conducted materials ...

In conjunction with the geological conditions of East China Sea, bearing performance monopile and single-suction bucket foundations is compared analyzed in shallow deep-sea under static horizontal loads. Furthermore, statistical data wind wave from 2010 to 2020 Sea were tabulated into amplitude curves applied two form dynamic loads, performances loads analyzed. The results show that typical suc...
