Research on Solution of Ship Low Sulphur Fuel based on IMO Sulphur Limitation Regulation

Abstract

In recent years, the density of both domestic and international routes is generally at a high level. Intensive ship navigation frequency and ship number operations have brought many sulfur oxides, nitrogen oxides and other particulate matter to the port, resulting in increasingly serious port pollution, which has become one of the main sources of air pollution, and ship exhaust emissions are causing environmental pollution in coastal areas. As well as the main sources of port pollution, the pollution problem should not be underestimated. “Air pollution from maritime transport causes about 1450 to 37500 premature deaths each year and brings short-term and long-term changes to the climate system,” the IMO reiterated in response to the seriousness of the problem that all ship fuels should meet sulfur content below 0.5% starting from January 1,2020[1]. In view of this regulation, this paper systematically analyses three low-sulfur fuel solutions at present, and summarizes the optimal solution from the aspects of economy, feasibility and sustainability, and the comparative study of three different types of the optimal solution is carried out, that is, to refine the optimal solution again and put forward the applicable technology in the optimal solution.
