The prevention of air pollution from ships has been much discussed at the IMO over the years. As a result, MARPOL Appendix VI was established and took affect in May 2005. The regulation is enforced for five years and it will be reviewed again. For the application progress purpose, the 12th Conference on Bulk Liquids and Gases [BLG 12] was held on February 2nd - 4th, `08 at London. The execution time for a concrete numerical value of the 2nd and 3rd regulation has been agreed. The 3rd regulation is mainly concerning a decrease of the emissions on NOx, SOx and PM (Particulate Matter). The regulations impact on the economic aspect in the treatment process must also being considered. Authors have undertaken research of exhaust gas treatment system for pollution from ships by applying the advanced technology of seawater scrubber. The exhaust gas and waste water treatment system with high reliability and safety devices has been developed to remove particulate matter (PM) and poly-hydrocarbon compounds (PAHs). In a testing stage, the removal rate of NOx, SOx and PM from diesel engine shows the effective value of 80%.
