It is proposed that a reliability prediction model for prototype marine energy converters (MECs) could predict incident failures, analyse a system's future performance and compare different architectures, so that lower failure rate devices could be developed. Challenges in establishing such a method include the absence of historical data and the low level of deployment of wave and tidal stream generation technology in comparable locations. In speaking of MEC reliability concepts, it is useful to present the definition of probability-based reliability and reliability modelling. Based on MIL-STD721C, reliability in general is the probability that a part or system will perform its intended function for a specific time interval under stated conditions. It is measured quantitatively and consists of several reliability characteristics, the results being different for non-repairable and repairable systems/sub-systems/assemblies/ sub-assemblies/components. This paper sets out a system assessment method to quantitatively evaluate MEC technology reliability.
