Study on implications for design of fuel transition in decarbonization of ship

Abstract

In this paper, an evaluation method for effects of zero emission fuels on ship designs is proposed, and its usefulness is demonstrated by trial examples as follows, 1) A method to combine the price of alternative fuel and the additional cost on bunkering facility with the design development of individual ship under variable conditions is proposed. 2) From a trial analysis for an Aframax tanker, conditions in which an alternative fuel becomes superior from a cost aspect are shown in connection particular ship designs. 3) Possibility of a total simulation which gives the optimum design for particular ships under conditions of fuel supply and ship operation, are shown using the proposed method.
