SURFTEC: SUrvivability and Reliability of Floating Tidal Energy Converters

识别和了解潮汐能转换器(TEC)上的极端负载和疲劳负载、了解极端环境(主资源除外)以及确定可访问性、可维护性标准、故障间隔和相关设备生命周期，这些都是决定设备和阵列部署的资本支出和运营成本的重要因素。该项目将为设计优化提供整体愿景，以确保浮动TEC(FTEC)的可靠性和生存能力。计算模型和实际海上部署测量将提供一种工具，为FTEC设备和阵列提供最佳作战战略，并最大限度地提高生存能力和可靠性。斯旺西大学将开发一种通用的BEMT代码，通过与项目合作伙伴Ocean Flow Energy、EMEC和Black and Veatch密切合作，确定此类技术需要测量的最重要参数，从而能够在基础水平和物理层面上对FTEC进行数值研究。在Sanda Sound部署现场为Ocean flow Energy 1：4比例Evopod原型所做的测量，包括设备和海况数据集上的负载，将用于验证FTEC的BEMT模型。然后，将使用EMEC提供的环境数据(包括极端数据)来测试通用的BEMT FTEC模型。在与Black和Veatch的合作中，最终的负荷预测将用于估计部件的疲劳和故障。这将导致制定业务战略和设计指南，以最大限度地提高FTEC的生存能力和可靠性。

Identifying and understanding extreme and fatigue loads on tidal energy converters (TEC), understanding environmental extremes (other than main resource), and determining accessibility, serviceability criteria, fault intervals and associated device life cycles, are all important factors that can determine CAPEX and OPEX cost of devices and array deployments. This project will provide a holistic vision for design optimisation to ensure, reliability and survivability for floating TECs (FTECs). Computational modeling and real sea deployment measurements will provide a tool to inform the optimum operational strategy and maximise survivability and reliability for FTEC devices and arrays. Swansea University will develop a versatile BEMT code to enable the study of FTECs numerically at a fundamental level and physically by working closely with project partners Oceanflow Energy, EMEC and Black and Veatch to determine the most important parameters to be measured for this type of technologies. Measurements taken at the Sanda Sound deployment site for the Oceanflow Energy 1:4 scale EVOPOD prototype, including loads on the device and sea condition datasets, will be used to validate the BEMT model for FTECs. A generic BEMT FTEC model will then be tested using environmental data, including extremes, provided by EMEC. In collaboration with Black and Veatch the resulting load predictions will be used to estimate component fatigue and failure. This will lead to the development of an operational strategy and design guidance to maximise survivability and reliability of FTECs.
