The Plug-in Hybrid Electric Superyacht: An operational data-driven design

This study aims to provide a proof of concept of a plug-in hybrid electric superyacht. In this way, the yachting industry can help reduce carbon emissions worldwide and potentially increase comfort levels. The concept takes advantage of the typical operating profile of a yacht. A statistical analysis is performed to discretise this and obtain parameters for the all-electric design range at design speed. The available shore power is examined by means of a questionnaire. Three options to compensate the battery weight are presented to minimise impact on design. The resulting concept versions are checked for their potential impacts on four aspects: Design, Sustainability, Comfort and Operation. This includes a life-cycle assessment that results in serious impacts on sustainability at an all-electric range of 2% to 3% of the full range capability. Finally, the concept is tested by means of a test cruise.Marine Technolog
