The research will investigate the nature of the loading patterns imparted onto tidal stream turbines when positioned and operated within an array and develop operational procedures to mitigate the impacts of these extreme loading patterns. Exposure to open sea wave climates with high wave-current interactions will influence the power generating, structural integrity, product durability and maintenance requirements of the technologies deployed. The research will undertake both experimental and numerical analyses in a manner that will make the results and findings transferable to real-life implementations. This will inform developers of the peak and fluctuating loads that devices are exposed to in a commercial array environment and will also identify and test mitigating actions to be implemented in order to ensure the robustness and sustainability of the array. The dynamic, cyclic loadings on a tidal stream turbine have been shown to depend on the current profile and wave characteristics which can increase the severity of these loads. This must be considered in the design of the turbine. A turbine in an array will be subjected to more complex flows due to its position in the array, which will result in more diverse loading patterns, which must be fully understood by the turbine designers and operators. The project will therefore evaluate and measure the loading and performance of different configurations of tidal stream turbine arrays using numerical modelling and model scaled experiments. The numerical modelling will use fluid and structural modelling. An existing and proven, instrumented, laboratory scale turbine design will used for the tests. Initial work on a three turbine array will be undertaken to create models of a full-scale turbine array to determine the power output, loading patterns and accurate life-fatigue analysis based on realistic site deployment conditions. This information will be formulated to provide a basis for the industry to evaluate anticipated performance, monitoring needs, operational best practice and maintenance regimes in order to deliver the lowest cost of energy from tidal arrays

该研究将调查潮汐流涡轮机在阵列内定位和运行时施加的负载模式的性质，并制定操作程序以减轻这些极端负载模式的影响。暴露于具有高波流相互作用的公海波浪气候将影响所部署技术的发电、结构完整性、产品耐用性和维护要求。该研究将以实验和数值分析的方式进行，使结果和发现可以转化为现实生活中的实施。这将告知开发人员设备在商业阵列环境中所面临的峰值和波动负载，并将确定和测试要实施的缓解措施，以确保阵列的稳健性和可持续性。潮汐流涡轮机上的动态循环载荷已被证明取决于电流剖面和波浪特征，这会增加这些载荷的严重性。在涡轮机的设计中必须考虑这一点。阵列中的涡轮机由于其在阵列中的位置而将受到更复杂的流动，这将导致更多样化的载荷模式，涡轮机设计者和操作员必须充分理解这一点。 因此，该项目将使用数值建模和模型规模实验来评估和测量不同配置的潮汐流涡轮机阵列的负载和性能。数值建模将使用流体和结构建模。现有的、经过验证的、仪器化的、实验室规模的涡轮机设计将用于测试。三涡轮机阵列的初步工作将创建全尺寸涡轮机阵列模型，以确定功率输出、负载模式和基于实际现场部署条件的准确寿命疲劳分析。这些信息将被制定为行业评估预期性能、监控需求、运营最佳实践和维护制度提供基础，以便从潮汐阵列提供最低成本的能源
