Meeting electric power needs on board while at sea with a steam turbo-generating plant driven by thermal energy recovered from the exhaust gas of the main diesel engine used to be a preferred method, because of the resultant saving in energy, for diesel ships with main propulsion plants of the 20,000 shp (14,710kw) class and above. In ships with relatively small main diesels of, say, the 10,000 shp (7,355 kw) class, however, the use of steam turbo-generating plants working on exhaust gas energy was considered virtually impossible because of the relative scarcity of such energy available. In respons to the increasing need for energy saving, Hitachi Zosen has developed a plant which enables a steam turbo-generator to be effectively used even with a marine main diesel whose output was previously considered insufficient for this purpose. The essential point of the new plant consists in reducing the steam pressure and thereby increasing the heat recovered by the exhaust gas economizer, and in adopting newly developed compact steam turbine working efficiently in such low pressure steam.(Wassmann)
