The engines used as the main engine of a ship vary depending on the fuel, size and output. Most of the ships are currently using internal combustion engines. This study examined the exhaust gas and air pollutants emitted by SAEBADA, the fishing training ship of Gyeongsang National University. It has a 2,427 kW main engine of Nigatta Engineering that uses marine gas oil (MGO) as fuel oil. It was measured in real time for each load. According to this measurement results, the engine of the ship is operated at an optimal load to reduce the emission concentration of air pollutants in the exhaust gas. For two days from May 13th to May 14th, 2020, a real ship emission gas measurement test was conducted on SAEBADA, the fishing training ship of Gyeongsang National University while operating the ship in four modes that were mainly composed of changes in output. The gas phase materials, particulate materials, exhaust temperature, etc., were measured. As a result of the test, the nitrogen oxide (NOx) emission of SAEBADA was Tier II level. It was found that when marine gas oil (MGO) emitted relatively less air pollutants than heavy fuel oil (HFO). In addition, it was found that the nitrogen oxide (NOx) emission in the high-load region was relatively less than in the low-load region regardless of the oil type and the aging of the engine. This may be due to the combustion state. Therefore, we intend to operate SAEBADA in an efficient and eco-friendly with the results of these real ship experiments.
