초록
Many marine vessels recently built are equipped with ultra-long stroke engines with high propulsion efficiency, and an engine de-rating technology and tuning technology are applied to comply with the more stringent environmental regulations and to reduce fuel consumption. Waste heat recovery systems (hereafter WHRSs) recover the waste heat from the exhaust gas emitted by the ship and use it in motor power for propulsion or in generators to supply electric power to the ship. In this case, it can be expected that the fuel consumption rate will be improved at the same speed, depending on the required horsepower reduction effect. However, this is accompanied by a tendency of increased torsional vibration excitation forces in the operating range of this system, compared to the standard engine without a WHRS. In this paper, the performance and the dynamic characteristics of a marine diesel engine, with application of a waste heat system, are reviewed, and the effects on the torsional vibration of a corresponding propulsion shafting system, in an ultra large container vessel equipped with the corresponding system, are studied.
Abstract
Many marine vessels recently built are equipped with ultra-long stroke engines with high propulsion efficiency, and an engine de-rating technology and tuning technology are applied to comply with the more stringent environmental regulations and to reduce fuel consumption. Waste heat recovery systems (hereafter WHRSs) recover the waste heat from the exhaust gas emitted by the ship and use it in motor power for propulsion or in generators to supply electric power to the ship. In this case, it can be expected that the fuel consumption rate will be improved at the same speed, depending on the required horsepower reduction effect. However, this is accompanied by a tendency of increased torsional vibration excitation forces in the operating range of this system, compared to the standard engine without a WHRS. In this paper, the performance and the dynamic characteristics of a marine diesel engine, with application of a waste heat system, are reviewed, and the effects on the torsional vibration of a corresponding propulsion shafting system, in an ultra large container vessel equipped with the corresponding system, are studied.
