The vast majority of offshore wind resources are located in deep water regions. As the conventional offshore wind technology is restricted to shallow waters, there is a need for developing floating wind turbines (FWTs) that enables using this vast amount of energy.Floating offshore wind energy technology is in early-stage development. One of the largest barriers to further development of FWTs is their greater cost relative to bottom-fixed offshore wind turbines. One way to lower the cost of FWT technologies is through the increased reliability (i.e. reduced probability of failure) of FWT support structures, which are exposed to the harsh marine environment with great uncertainties in wind, wave and current loads.This PhD project will look into the improvement of reliability and the reduction of cost of FWT support structures, through the development of an efficient and robust reliability-based design and optimisation framework that is capable of efficiently and robustly achieving optimal design to meet target reliability.

绝大多数海上风资源都位于深水区域。由于常规的海上风能技术仅限于浅水，因此需要开发浮动风力涡轮机（FWT），该风力涡轮机可以使用大量的能源。浮动海上风能技术正在早期开发中。 FWT进一步发展的最大障碍之一是相对于底部固定的海上风力涡轮机的成本更高。降低FWT技术成本的一种方法是通过提高FWT支持结构的可靠性（即失败的可能性降低），这些结构暴露于风险，波浪和当前负载方面的严重不确定性，这些博士学位项目将通过可靠性的改善，以及能够有效的FWT成本来改善，并降低了FWT的成本和降低，并有效地效力，并降低了有效的效率和效率的成本。强大的实现最佳设计以满足目标可靠性。
