Lecture Abstract
报告摘要
中文内容根据会务组提供的英文Biography与Abstract整理。
单桩是海上风电机组最常用的基础形式，通常为打入海床的单根大直径钢管桩，用于支承风机结构。单桩需要安全承受风、浪、流以及风机持续运行产生的水平荷载和倾覆力矩。相关荷载既可能表现为紧急停机、极端波浪等单次峰值，也可能是波浪和转子运行产生的长期循环荷载，并常与风流形成的持续荷载共同作用；风荷载与波浪荷载还可能方向不一致。
报告将回顾过去十余年海上风电单桩在单调荷载和循环荷载设计方法方面的发展，并展望新的研究机会和工程挑战。内容将重点介绍中尺度现场试桩和室内模型试验成果，并讨论如何将试验结果纳入可供工程设计使用的统一框架。

Professor Byron Byrne holds the Ørsted / Royal Academy of Engineering Research Chair in Advanced Geotechnical Design at the University of Oxford where he leads on research into geotechnical engineering for offshore wind and other offshore renewable energy structures. He works collaboratively with industry to solve practical problems applying experimental work, at both laboratory scale and larger scale in the field, theoretical analysis and computational techniques, to develop simplified design methods for the engineer. He was Principal Investigator for the Carbon Trust / Ørsted / Industry funded PISA project (2013-2018), which has delivered new design methods for large diameter offshore wind turbine monopiles, now applied to many constructed offshore wind farms. He currently leads on the Oxford–Ørsted Research Framework PICASO project (2018-2028) on cyclic loading for offshore wind foundations and was a Co-Investigator on the EPSRC / industry ALPACA Project (2018-2023). He is a Co-Investigator on the Strathclyde / Oxford / Edinburgh EPSRC CDT for Wind and Marine Energy Systems and Structures (2019-2027), and was the Oxford Director, and Co-Investigator, for the Cranfield / Oxford / Strathclyde EPSRC CDT for Renewable Energy Marine Structures (2014-2022). He is a Co-Director of the EPSRC Supergen Offshore Renewable Energy Impact Hub 2023 led by Plymouth University. He is a Fellow of the Royal Academy of Engineering and of the Institution of Civil Engineers.
Abstract — English+
The monopile is the most common foundation for an offshore wind turbine. It is a singular tubular pile, often driven into the ground, upon which a wind turbine can be located. Monopiles must be designed to safely resist the lateral loading and overturning moments derived from the environmental conditions acting on the turbine structure, including the wind, wave and current loading, as well as the continuing operation of the turbine itself. The applied loading can range from one-off extreme peaks (e.g. rotor emergency stop, extreme wave), to regular and repetitive cycling (e.g. waves, rotor operation), often combined with a sustained load (e.g. current, wind). It is also possible that the loads derived from waves and wind may not be aligned. This paper will provide an overview of the development, over the past decade, of new design methods that address monotonic and cyclic loading of monopiles, as well as looking forward to new opportunities and challenges. The paper will highlight the outputs from medium scale pile field testing, as well as laboratory model testing, exploring the results within an appropriate framework that can be applied in design.
