Abstract

Full electric vessel has been under development to fulfil the restrict emission control strategy set up by International Maritime Organization requiring marine industry to reduce 40% of carbon dioxide emission by 2030 and 50% of greenhouse gases by 2050. This paper provides an risk assessment for a selected battery powered full electric vessel. Through identifying hazards and estimation of frequency and consequence, the most severe hazards will be determined so the top events will be analyzed by conducting event-tree analysis to evaluate the reliability. The results indicate the battery powered ship has a lower risk impact than traditional cruise ships.
