Survivability of Floating Offshore Wind Turbines using CFD

随着该行业进入更深的水域，浮式海上风力涡轮机(FOWT)似乎是一个合乎逻辑的步骤。然而，FOWT和系泊耦合系统动态响应的不确定性是一个高风险，特别是由于气候变化，风暴条件的频率越来越高。在极端风浪联合作用下，FOWTs的“生存能力”仍然是一个关键问题，需要进行基础研究，以降低项目的风险并减少不确定性。数值模拟可以提供全面工程分析所需的定量描述，从而能够正确地表示气动和水动力状态。然而，大浪冲击和极端风荷载需要使用高保真模型，如计算流体动力学(CFD)，仍需付出相当大的努力来提高对这些工具的信心。

Floating offshore wind turbines (FOWT) appear to be a logical step, as the industry moves into deeper water. However, uncertainty in the dynamic response of FOWT and mooring-coupled systems represents a high risk, particularly with the increasing frequency of storm conditions, due to climate change. 'Survivability' of FOWTs, under the combined loading from extreme wind and waves, remains a key concern and underpinning research is needed to de-risk projects and reduce the uncertainties.Numerical modelling can provide the quantitative description required for engineering analysis at full-scale making it possible to represent both the aero- and hydro-dynamic regimes correctly. However, large wave impacts and extreme wind loading require the use of high fidelity modelling, such as Computational Fluid Dynamics (CFD), and considerable effort is still required to improve the confidence in these tools.
