It is essential, in the philosophy of energy saving ships, that the system to be proposed must keep proven reliability and stability or adaptability against various circumstance of ship's operation, such as grade of uel oil, quality and number of ship's crew, level of maintenance, course of ship and condition of sailing, etc.<BR>Placing emphasis on this basic concept, Hitachi Zosen has developed a uel saving ship since 1976 which consists of the twin-bank engine, the low pressure turbo generator and the single-loop steering gear.<BR>The newly developed twin-bank engine is the most reliable two-stroke, low-speed, crosshead type diesel engine together with reduction gear, enabling propeller to be selected at any rate of revolutions. Of the various advantages of the twin-bank engine, the most important ones are the capability of burning low-grade uel oil and compactness which allows smaller engine room space, even with cross-head type.<BR>Also the newly developed turbo generator makes it possible to obtain the electric power needed on board and the stearing gear contributes to reduction of the propelling power loss.<BR>Thus the reduction of uel consumption reach 20-35% in total.
