… decades, offshore renewable energy is expected to play a crucial role in the decarbonisation of global electricity supply essential for limiting anthropogenic greenhouse gas emissions to an acceptable level. The cost of utilising expensive vessels to install and maintain these marine energy devices represents a significant proportion of their life-cycle cost and one of the major barriers to their continued development. It is …
