The international shipping transportation industry becomes gradually important in the field of national economic development. It is explained by means of an increase in a number of ships nowadays, and it also expands the operating routes on international routes including the North of America, Baltic Sea, and emission control areas (ECAs). The energy efficiency of ships is very necessary to respond to the regulations of the International Maritime Organization (IMO). Moreover, the operational parameters have a significant meaning in supervising and monitoring the engines on a ship. They completely depend on the navigation environment condition. So, selecting the optimal operational parameters’ component is a target of this study. In this chapter, a study on the energy efficiency of ship by decreasing the fuel consumption of the main engine for a certain ship namely M/V NSU JUSTICE 250,000 DWT of VINIC shipping transportation company in Vietnam is by the method of artificial neural networks (ANNs). In particular, these studies were conducted by the classification and clustering method of artificial neural networks (ANNs) based on the experimental database of M/V NSU JUSTICE 250,000 DWT. The results of this chapter will solve the energy efficiency issue on ships nowadays and contribute the aims in the next studies.

The IMO (International Maritime Organization) of MARPOL 73/78, Regulations for the Prevention of Air Pollution from Ships, has been adopted and took effect from May 2005 and had significantly to the present. The increases in a number of ships are leading to a large of number of exhaust gas emission into the environment. It is main reason that the Annex VI, MARPOL 73/78 is extremely necessary to require the ships need to comply. Furthermore, the marine fuel is used mainly for marine diesel engine nowadays, heavy fuel oil with high sulphur content. However, the IMO’s regulations show that from January 1, 2020, fuel oil that is used on board should have no more than 0.50% sulphur content in order to protect the environment. Its benefit will have positive effect to the environment. On another side, the diesel engine operation especially the corrosion phenomenon for all piston-cylinder components will have negative effect due to the use of low sulphur fuel oil (LSFO). This chapter concentrates on researching the above phenomenon and gives some methods to restrict the negative influence on using the kind of low sulphur fuel oil. The results are fundamental knowledge for all vessels to comply the regulations of MARPOL 73/78 while sailing on ECAs.
