Abstract: Introduction.The relevance of scientific research is determined by the strengthening of requirements for emissions into the atmosphere of harmful substances contained in the exhaust gases of the main ship engines and the impact of roughness on the cost and consumption of ship fuel.The international convention MARPOL 73/78, adopted by the International Maritime Organization (IMO), is the main document containing a number of measures to prevent pollution of the marine environment from ships.Purpose.The relevance of scientific research is determined by the strengthening of requirements for emissions into the atmosphere of harmful substances contained in the exhaust gases of the main ship engines and the impact of roughness on the cost and consumption of ship fuel.The international convention MARPOL 73/78, adopted by the International Maritime Organization (IMO), is the main document containing a number of measures to prevent pollution of the marine environment from ships.In the field of energy efficiency and the cost of energy used on ships, not so many scientific works have been conducted recently by various research organizations and universities.Method.As an analytical tool, the authors used the Ishikawa diagram, which became an excellent means of visualization and organization of knowledge, which simplified the understanding and diagnosis of the problem.Results.The results of the study showed that the ways to reduce the cost of the ship's fuel economy, combat harmful emissions into the atmosphere, and significantly reduce operating fuel costs depend on many factors.The Ishikawa diagram made it possible to identify key interrelationships between various factors and to more accurately understand the researched process; contributed to the identification of the main factors that have the most significant impact on the development of the considered problem, as well as prevention or elimination of the effect of these factors.Scientific novelty.The team of authors determined that, first of all, fuel consumption is influenced by the parameters of the roughness of the surfaces of the propeller and conducted an analysis of this influence.Practical importance.The article is devoted to the analysis of the effect of propeller roughness on ship fuel consumption.The authors analyzed the impact of propeller manufacturing materials on its roughness and ship fuel consumption.In order to review the action of possible factors and to separate the most important causes, the action of which produces specific consequences and is subject to management, the authors used the construction of Ishikawa diagrams as an analytical tool.
