For marine energy to compete with other energy systems, a step reduction in CAPEX/OPEX and increase inavailability times (AVT) is required. Albatern WaveNet scalable wave energy convertors (WECs) at 7.5kW scale,in grid arrays, have achieved a several fold CAPEX reduction compared with alternative designs, and at 1GWgrid scale aim to achieve a levelised elecricity cost of £150MWhr, competitive with offshore wind, by 2024. Asan enabling technology for this target an online, in-service, risk driven; condition monitoring, predictivemaintenance management and design upscaling tool (RISKMAN) will be developed for WECs FOR THE FIRSTTIME, to achieve a step OPEX reduction, AVT enhancement and design life optimisation. RISKMAN will inputmonitored fatigue cycle (vibration spectra) into theoretical models of fatigue life, refined by historic reliabilitydata, to derive probability distribution functions for the remaining life of generator components and henceoptimised maintenance schedules. RISKMAN will be a generic system applicable to all types of WECs, forexploitation of all the huge wave resources in poor, off-grid and island communities in developing countries.

为了使海洋能源与其他能源系统竞争，需要逐步降低CAPEX/OPEX并增加不可用时间（AVT）。Albatern WaveNet可扩展的波浪能转换器（WEC）在7.5kW的规模，在网格阵列中，与替代设计相比，已经实现了几倍的资本支出减少，并且在1GW网格规模下，目标是到2024年实现150 MWhr的电力成本，与海上风电竞争。作为实现这一目标的一项技术，将首次为WEC开发在线、在役、风险驱动的状态监测、预测性维护管理和设计升级工具（RISKMAN），以实现逐步降低运营成本、提高AVT和优化设计寿命。RISKMAN将监测到的疲劳周期（振动频谱）输入到疲劳寿命的理论模型中，并根据历史可靠性数据进行优化，以获得发电机部件剩余寿命的概率分布函数，从而优化维护计划。RISKMAN将是一个通用系统，适用于所有类型的WEC，用于开发发展中国家贫困、离网和岛屿社区的所有巨大波浪资源。
