A Feasibility Study on LPG as Marine Fuel

Abstract

With the upcoming stricter emission rules fast approaching and the requirements for higher quality fuel, it is inevitable that there will be a change of fuel from HFO to cleaner options. These changes are driven by the knowledge of the health problems associated with emissions from ships in coastal areas. One viable option for meeting these demands for reduced emission is to utilize LPG as a marine fuel. This thesis investigates the harmful chemicals that are present in the exhaust gases, followed by introduction of LPG. Transport options for LPG and existing motor technology is presented and the feasibility of LPG as a fuel option on the European / Swedish market is studied. The conclusion from this study is that sufficient infrastructure for distribution of LPG is in place to serve potential marine market demand. Motor technology for using LPG as fuel has been developed for a wide range of power output. The economic incentive in the fuel price difference alone is likely to attract ship owners to invest in LPG fueled fleet.
