Abstract

In the shipping transportation industries, they brigh a lot of economical values with rising a number of fleets. Unfortunately, this development always encloses to the environmental pollution issue. “International Maritime Organization (IMO)” has been adopted all member states of nations that are being operated and managed the ocean by means of giving out the “International Convention for the Prevention of Pollution from Ships (MARPOL 73/78)”. In where, the exhaust gas cleaning system has been known as an optimal solution to reduce SOx emissions from diesel engine exhaust gas on board. In this article, the structures of sulphur scrubber exhaust gas cleaning systems have been researched along with their cleaning methodology. Based on the working performance of their systems on ship, there is a comparison of efficiency that it will help ship-owners selected effectively in ship operation. The results of this article have identified that the reduction of SOx gas emission reaches to 95% and PM (Particulate Matter) reduction efficiency aims 60%. So, the use of Scrubbers to reduce sulphur content in marine diesel engines approaches reliably in ship operation nowadays
