The offshore wind industry has experienced significant growth in recent years, and continues to expand both in the UK and worldwide. Most of the offshore wind turbines installed to date are located in relatively shallow water and are mounted on fixed bottom support structures. Given the limitation of suitable shallow water sites available with high wind resources and also to reduce the environmental and visual impact of turbines, it is necessary to extend wind turbines to deeper water through the development of floating offshore wind turbine (FOWT) systems, which mount wind turbines on floating support platforms. The project aims to fill an important gap in the design, manufacturing and testing of emerging FOWT techniques by specifically characterising extreme loading on FOWTs under complex and harsh marine environments. These are typically represented by storm conditions consisting of strong wind, extreme waves, significant current, rising sea level and complex interplay between these elements, through a coordinated campaign of both advanced CFD modelling and physical wave tank tests. This has direct relevance to the current and planned activities in the UK to develop this new technology in offshore wind. In addition, the project aims to develop a suite of hierarchical numerical models that can be applied routinely for both fast and detailed analysis of the specific flow problem of environmental (wind, wave, current) loading and dynamic responses of FOWTs under realistic storm conditions. As an integral part of the project, a new experimental programme will be devised and conducted in the COAST laboratory at the University of Plymouth, providing improved understanding of the underlying physics and for validating the numerical models. Towards the end of the project, fully documented CFD software and experimental data sets will be released to relevant industrial users and into the Public Domain, so that they may be used to aid the design of future support structures of FOWTs and to secure their survivability with an extended envelope of safe operation for maximum power output.

近年来，海上风力行业的增长显着增长，并且在英国和全球范围内都在不断扩大。迄今为止，大多数安装的海上风力涡轮机位于相对较浅的水中，并安装在固定的底部支撑结构上。鉴于合适的浅水站点的限制，还可以减少涡轮机的环境和视觉影响，因此有必要通过开发浮动海上风力涡轮机（FOWT）系统将风力涡轮机扩展到更深的水，该系统将风力涡轮机安装在浮动支撑平台上。该项目旨在通过专门表征复杂和苛刻的海洋环境下的禽类的极端负载来填补新兴禽类技术的设计，制造和测试的重要空白。这些通常由风暴条件代表，包括强风，极端波，明显的电流，海平面上升和这些元素之间的复杂相互作用，这是通过高级CFD建模和物理波罐测试的协调运动。这与英国当前和计划中的活动有直接相关，以开发在海上风中的这项新技术。此外，该项目旨在开发一套层次数值模型，这些模型可以通常应用于对环境（风，波，波，电流）负载的特定流量问题的快速和详细分析，而FOWT在现实风暴条件下的动态响应和动态响应。作为该项目不可或缺的一部分，将在普利茅斯大学的海岸实验室制定新的实验计划，从而提高对基础物理学的了解并验证数值模型。在项目结束时，已充分记录的CFD软件和实验数据集将被释放给相关的工业用户并进入公共领域，以便它们可以用来帮助设计Fowts的未来支持结构，并通过扩展的安全操作来确保其生存能力，以最大程度的动力输出。
