This project aims to develop a framework that will integrate data collected and recorded through a Structural Health Monitoring (SHM) system for marine energy converters, in order to estimate reliability levels at component and system level in real time and evaluate its ability to further fulfil its intended function. Obtaining a more well-informed understanding of the actual state of the system, alternative operational strategies can be adopted, particularly taking into consideration its residual capacity after extreme environmental events, optimizing its inspection and maintenance scheduling and hence reducing the OPEX. Application of the developed framework on an existing prototype wave device, already developed by the Chinese partners, will allow its validation and extension to future applications. This reference case will be employed in order to classify its components and determine potential failure modes and limit states to assess failure. From the key failure mechanisms that will be identified, arrangements for Structural Health Monitoring will be proposed obtaining data from relevant measurements (ie strains and accelerations) that can then inform the reliability evaluation in real time, updating its operational strategy, particularly taking into consideration residual capacity after extreme environmental events. Outcome of the project will be a generic framework applicable to a range of marine energy devices.

该项目旨在开发一个框架，该框架将整合通过海洋能源转换器的结构健康监测（SHM）系统收集和记录的数据，以便在真实的时间内估计组件和系统级别的可靠性水平，并评估其进一步履行预期功能的能力。通过对系统的实际状态有更全面的了解，可以采用替代运营策略，特别是考虑极端环境事件后的剩余容量，优化其检查和维护计划，从而降低运营成本。在现有的原型波设备，已经由中国合作伙伴开发的应用程序开发的框架，将允许其验证和扩展到未来的应用。将采用该参考案例对其组件进行分类，并确定潜在失效模式和极限状态，以评估失效。根据将要确定的关键失效机制，将提出结构健康监测的安排，从相关测量（即应变和加速度）中获取数据，然后可以真实的时间通知可靠性评估，更新其运营策略，特别是考虑极端环境事件后的剩余容量。该项目的成果将是一个适用于一系列海洋能源装置的通用框架。
