This thesis investigates the optimisation of the structural design and manufacture of the fibre-reinforced composite components of the CCell wave energy converter. An innovative solution was required to maximise the power output and strength of the composite paddle (the CCell prime mover), whilst also minimising the mass and cost. The main outputs of this thesis have been the development of bespoke procedures for the design and manufacture of the composite components of the CCell device. These include structural numerical modelling of the paddle laminate and joints; development and optimisation of the resin infusion process for the paddle manufacture; development of fatigue and LCOE models to inform through-life behaviour and minimise lifetime costs. Furthermore, work has been carried out to develop electronic systems to assist the control and monitoring of the system in operation. These systems reduce the loading and therefore allow further optimisation of material usage. These procedures have led to the production of a full-scale prototype device which was deployed in Mexico and seven small-scale devices for laboratory testing. The procedures developed will be used to develop and deploy further iterations of the composite components of the CCell device.
