Wave and Tidal Generation Devices: Reliability and availability — Recommend this title to your library

This paper sets out the reliability theory relevant for marine energy convertor (MEC); however, the amount of reliability data available for such devices is severely limited. The theory below is set out with this in mind so that MEC innovators, developers and operators can collect the appropriate data; see how reliability can influence their machines and based on the data make appropriate design, deployment and maintenance decisions. A 1-2 MW MEC is a complex, robotic, electro-mechanical generating machine mounted in or on a steel and concrete structure, with a steel or concrete foundation or moored to steel anchors or concrete foundations.
