Abstract:

Wave Energy Propulsion for Pure Car and Truck Carriers (PCTC's)

The development of ocean wave energy technology has in recent years seena revival due to increased climate concerns and interest in sustainable energy.This thesis investigates whether ocean wave energy could also beused for propulsion of commercial ships, with Pure Car and Truck Carriers(PCTC's) being the model ship type used. Based on current wave energyresearch four technologies are selected as candidates for wave energy propulsion:bow overtopping, thrust generating foils, moving multi-point absorberand turbine-tted anti-roll tanks.Analyses of the selected technologies indicate that the generated propulsivepower does not overcome the added resistance from the system at the shipdesign speed and size used in the study. Conclusions are that further waveenergy propulsion research should focus on systems for ships that are slowerand smaller than current PCTC's.
