Owing to high operation cost of traditional power systems and serious environmental situation, hybrid power system is increasingly attracting attentions. Applying Life Cycle Assessment (LCA) approach, the objective of this paper is to evaluate and optimise the operational modes of hybrid system for a short-route ferry in Scotland, which combines generators and batteries and includes four operational modes based on the power requirements. A top-bottom design strategy is applied to build up the short-route ferry with hybrid power system in GaBi. The cradle to grave of the ferry is modelled referring to a practical ship life: construction, operation, maintenance and dismantling. Several operation cases with different power distributions were investigated with three phases: transiting, manoeuvring and at slip. The study indicated the most cost-effective power distribution between gen-sets and batteries and concluded the significant impacts on energy consumption and environment during the life cycle of a hybrid system. © 2018 Taylor & Francis Group, London.
