TWO JAPANESE DEVELOPMENTS AIMED AT SAVING FUEL

Japanese engine and hull designers continue to be active in their efforts to produce designs offering very considerable fuel savings to meet present economic circumstances. Two such Japanese developments are an advanced medium speed diesel plant from Mitsubishi Heavy Industries said to cut fuel costs by about 20 percent, as compared with a conventional low speed plant, and a new hull form from the Japan Ship Machinery Development Association claimed to reduce fuel consumption by around 15 percent without sacrificing the ship's speed. Each plant has two main engines of the Mitsubishi-Man V52/55 type driving a 1,800 kW main generator and a controllable-pitch propeller. Since the generator is driven by one of the two main engines, the former does not require any fuel oil for its own use--a big saving in fuel cost, because generators, if driven as independent units, consume expensive diesel oils and light oils. In this respect, engine plants of this type are especially suitable for such vessels as LPG carriers and refrigerated cargo carriers which consume large volumes of electricity during normal navigation.
