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.
