The next frontier for offshore wind energy is moving further out to sea to avail of stronger and more consistent wind speeds. In these water depths, wind turbines are installed on floaters tethered to anchors in the seabed. Geotechnical design of anchors is inherently conservative, having been shaped by technical and economic considerations of oil and gas facilities. The offshore wind energy industry cannot afford to adopt such conservatism if floating wind is to become commercially viable. This project will, through numerical developments, geotechnical centrifuge modelling and field testing, develop the science that will lead to a reliability-based geotechnical design approach to make floating offshore wind energy economic and viable.

海上风能的下一个前沿领域是进一步向海上延伸，以利用更强、更稳定的风速。在这些水深中，风力涡轮机安装在系在海底锚上的浮体上。锚的岩土工程设计本质上是保守的，是根据石油和天然气设施的技术和经济考虑而形成的。如果浮动风电要在商业上可行，海上风能行业就不能采取这种保守态度。该项目将通过数值开发、岩土离心机建模和现场测试，发展科学，从而形成基于可靠性的岩土设计方法，使浮动海上风能经济且可行。
