Offshore wind turbine environment, loads, simulation, and design

Abstract: In the design, certification, and optimization of offshore wind turbines, extensive loads simulation is inevitable to develop reliable and cost-effective turbines. Description of the marine environment is based on a variety of techniques taking the stochastic nature of both, the wind and the water waves into account. The wind turbine is a highly dynamic system including effects of heavy rotating machinery and other significant nonlinearities leading to static, cyclic, transient, and stochastic loads. Due to th… Show more

“…Wind turbines in an offshore environment are exposed to combined wind and wave loading, both of which are natural phenomena occurring in a stochastic, irregular manner. 2 The stochastic fluctuations of the wind are considered to be one of the most serious load problems for wind turbines and contribute considerably to material fatigue. 3 In numerical simulations, wind and wave loading are difficult to reproduce accurately, and this is therefore a significant cause of simulation error.…”

“…The main use of such a model would be as a starting point for a probabilistic analysis. One of the main challenges for structural optimization of wind turbine support structures is the sheer amount of time-domain simulations needed for a comprehensive assessment, which borders on the region of a few thousands [2,5]. It would be highly welcome to obtain a more efficient, yet still highly accurate, way of predicting fatigue damage in a support structure.…”

“…Wind turbines are highly dynamic and tightly coupled systems that characterize a multiphysics problem, and their structural design and assessment pose specific challenges [24,25]. The rotor of a wind turbine is subject to aeroelastic effects that result in feedback of the rotor motion on the forces acting on the supporting structure.…”
