An efficient source of renewable energy, which is increasingly the preferred solution for realising the UK's short- and long-term energy demand, is offshore wind. According to the UK's Renewable Energy Roadmap and the national target to reach up to 50 GW of installed offshore wind capacity by 2030, deployment of further offshore wind farms will be boosted over the coming decades. The dominant majority of the UK's offshore wind turbines are supported using monopile foundations which are fabricated by welding large thickness steel plates. These support structures are subjected to severe cyclic loading condition during service; therefore, they need to be designed against fatigue failure for a desired target life which is typically between 20 and 25 years. The aim of this PhD project is to evaluate the level of fatigue damage in the support structures at the end of initial design life and explore possible engineering solutions for life extension of the existing assets.

越来越多的有效的可再生能源来源，它是实现英国短期和长期能源需求的首选解决方案。根据英国可再生能源路线图和全国目标，到2030年，安装的离岸风能最高可达50 gw，在未来几十年中，将提高进一步的离岸风电场的部署。英国近海风力涡轮机的主要多数是使用单层基础来支撑的，这些基础是通过焊接大厚的钢板制成的。这些支撑结构在服务过程中受到严重的循环载荷条件；因此，它们需要针对所需目标寿命的疲劳失败进行设计，该目标寿命通常在20到25年之间。该博士学位项目的目的是评估初始设计寿命结束时支撑结构中疲劳损害的水平，并探索可能的工程解决方案，以延长现有资产的寿命。
