Performance and emission analysis of marine diesel engines during ship maneuvering

Sea transport is the most economical and convenient transportation option for long distance transport. From the 19th century with the realization of the industrial revolution, it has entered into a rapid development of maritime transport. Developing technology and international treaties necessiated more sensitive to changes in the environment of this technology. In this context, IMO (the International Maritime Organization) MARPOL annex 6 (1997 protocol ) was enacted in 2005. Air pollution is causing global warming, the depletion of the ozone layer, acid rain, damage to the human health. Keping constantly under the control of the operation and performance of diesel engines with low air pollution is important. Due to variable loads during maneuvers of ships gases emitted into the atmosphere is damaging the air quality in the port environment. Therefore, they must perform the maneuver of the vessel as soon as possible. In addition, operation of the generators during their stay in the port causes air pollution. During the maneuver for main engine, 20% CO2 and 800% emissions produced specific emissions more than normal operating conditions. In addition, the emissions produced by two generator at same power load is 16% CO2 and 320% CO more specific emissions than one generator operating conditions. In this study, ships exhaust harmful gases released into the environment while maneuvering and port stays are illustrated numerically. During the maneuvering to reduce emissions and port stays were made to run during the determination of the number of the generators. Annual and periodic emission calculations will be based on the calculations methods.
