Hybrid Power Retrofitting Study for a Platform Supply Vessel

Abstract This paper takes a platform supply vessel as the parent vessel and introduces its power system configuration and working conditions; to meet the requirements of carbon emissions reduction and improve economic efficiency, a preliminary program of marine hybrid power retrofitting of diesel generator sets assisted with Lithium battery module is proposed on the base of analyzing its working conditions, the fuel consumptions and carbon emissions are compared between before and after the retrofitting, etc. According to the calculation results, the paper concludes that the investment payback period of the refitting is about 6.38 years, and this refitting will have good economic benefits and social benefits.
