ABSTRACT

Selection of the most efficient steaming speed in shipping word have become an alternative solution for assisting shipping companies in planning a business strategy, reducing the ship operational costs and emission. The application of slow steaming on ships has several advantages, both economically and environmentally. Slow steaming is capable of reducing fuel consumption and exhaust emissions, because these are usually a cubic function of ship speed. Slow steaming can be performed by reducing the service speed of the ship with the aim of minimizing the fuel consumption and ship emissions. There are three different levels of steaming speed known in the shipping sector: slow, extra and super slow steaming. A decision about the most efficient steaming speed should be made by shipping companies considering elements of technical, financial, and environmental aspects. This paper addresses to make a decision as to which one of them will be the most efficient steaming speed for shipping companies. The decision-making method is conducted using Elimination and Choice Expressing Reality (ELECTRE). ELECTRE is a multi-criteria decision making (MCDM) analysis model that is proved to be effective in ranking several decision making problems. The results show that the chosen speed can provide economic and environmental benefits.
