项目摘要

The vast ocean surface populated by wind-generated waves is where atmosphere and ocean interact. It is also where maritime and offshore renewable energy industries have to operate to secure future sustainable energy. Wave breaking provides the upper limit to how large waves may become and is the mechanism for how they dissipate energy. Breaking in crossing seas, the harshest conditions for shipping and offshore renewable energy (ORE) design, is poorly understood. A recent case study of the famous Draupner rogue wave by four of the investigators (M.L. McAllister et al. (2019) Laboratory recreation of the Draupner wave and the role of breaking in crossing seas. J. Fluid Mech. 860, 767-786) has shown that breaking in such seas is fundamentally different: it limits maximum wave height much less and is potentially much less dissipative. As a consequence, existing breaking criteria as implemented in wave forecasting tools and offshore design guidelines are not valid and unreliable in crossing seas. Through collaboration with DNV GL (an international accredited registrar and classification society), the European Centre for Medium-Range Weather Forecasts (a world-leading operational wave forecasting agency) and Shanghai Jiao Tong University (ranked first in the world for ocean engineering in the Shanghai Ranking), this project aims to develop and experimentally and numerically validate robust new wave breaking and dissipation criteria appropriate for highly directionally spread and crossing-sea conditions and implement these in wave forecasting tools and offshore design guidelines. The UK and Ireland possess substantial offshore wind resources that are capable of making major contributions to their national and international energy supply. A key problem in developing such resources is designing against the harsh ocean environment that prevails in the territorial waters of both countries. The design challenge is even greater in China (with an estimated 100bn offshore wind market), where candidate sites for offshore wind farms are exposed to typhoons, in which crossing sea conditions have an increased likelihood. The proposal will address this challenge through extensive large-scale experiments in two globally unique wave, FloWave at the University of Edinburgh (part of the UK ORE testing infrastructure) and the Ocean Basin at Shanghai Jiao Tong University, state-of-the-art numerical simulations and the development of new theory. The 30-month proposal has an investigating team across four universities (Oxford, Edinburgh, Manchester and University College Dublin) consisting of a PI, four Co-Is and a Researcher Co-I, three of whom are early-career researchers.

由风产生的波浪构成的广阔海洋表面是大气和海洋相互作用的地方。这也是海洋和近海可再生能源行业必须运作以确保未来可持续能源的地方。波浪破碎提供了波浪可能变得多大的上限，并且是它们如何耗散能量的机制。对于航运和海上可再生能源（ORE）设计最恶劣的条件，即跨海航行，人们知之甚少。最近的一个案例研究著名的Draupner流氓波的四个调查人员（M. L。麦卡利斯特et al.（2019）Draupner波的实验室重建和破碎在穿越海洋中的作用。J. Fluid Mech.860，767-786）已经表明，在这样的海洋中破碎是根本不同的：它对最大波高的限制要小得多，并且潜在地耗散要小得多。因此，在波浪预报工具和海上设计指南中实施的现有破碎标准在跨海中是无效和不可靠的。通过与DNV GL合作（一个国际认可的登记机构和船级社）、欧洲中期天气预报中心（世界领先的海浪预报机构）和上海交通大学（上海排名海洋工程世界第一），该项目旨在开发并通过实验和数值验证适用于高强度波浪的新的破碎和耗散标准。定向传播和跨海条件，并在波浪预报工具和海上设计指南中实施这些。英国和爱尔兰拥有大量海上风电资源，能够为其国内和国际能源供应做出重大贡献。开发这种资源的一个关键问题是针对两国领水沃茨普遍存在的恶劣海洋环境进行设计。在中国（估计有1000亿美元的海上风电市场），设计挑战甚至更大，海上风电场的候选地点暴露在台风中，其中跨海条件的可能性增加。该提案将通过在爱丁堡大学的FloWave（英国ORE测试基础设施的一部分）和上海交通大学的海洋盆地两个全球独特的波浪中进行广泛的大规模实验，最先进的数值模拟和新理论的发展来应对这一挑战。这项为期30个月的提案由四所大学（牛津大学、爱丁堡大学、曼彻斯特大学和都柏林大学）的调查小组组成，其中包括一名PI、四名Co-I和一名研究员Co-I，其中三名是早期职业研究人员。
