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.

随着该行业进入更深的水域，浮动海上风力涡轮机（FOWT）似乎是一个合乎逻辑的步骤。然而，FOWT和系泊耦合系统的动态响应的不确定性代表了高风险，特别是由于气候变化，风暴条件的频率越来越高。FOWT在极端风和波浪的联合载荷下的“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风险并减少不确定性。数值模拟可以提供全尺寸工程分析所需的定量描述，从而可以正确地表示空气动力学和水动力学状态。然而，大型波浪冲击和极端风荷载需要使用高保真建模，如计算流体动力学（CFD），并且仍然需要相当大的努力来提高对这些工具的信心。
