The testing required to approve a marine energy converters (MEC) device for full service is extensive and could take over a decade, as demonstrated by the Pelamis wave energy converter (WEC) device. However, lessons are being learned and progress to reliable devices is accelerating. It is still important, however, to implement effective testing programmes, and this chapter describes design and testing methods that can be used to drive up the reliability of future MEC devices. Ultimately, it is this that will determine the success of MEC devices in capturing and delivering wave and tidal energy in the long term.
