Use of alternative fuels in shipping and fuel consumption calculation methods

Abstract

Just as in the automotive industry, electric, gas and hybrid cars, various alternative propulsion systems have emerged in the shipping industry in recent decades to replace and modernize conventional diesel systems. In the shipping industry, it has only been in the last few decades that more propulsion systems have been introduced, either in new ships or to replace the traditional system. The reasons are the increasingly stringent environmental regulations and reduction of operating costs, much of which is fuel cost. Knowledge
of fuel consumption data (measurement, calculation, estimation) is therefore very important for finding suitable alternative fuels for each type of ship. In this article, the authors would like to introduce the
features of the most feasible solutions and some of the methods for calculating fuel consumption for conventional diesel engines.
