NKK have developed a new type of control equipment for saving energy to the medium and small sized diesel ship. That is the one making it possible to use turbo-generator whenever ship is sailing. The conceptions of the control are as follows. 1) Turbo-generator is operated synchronously and shares the load with diesel generator. 2) Turbo-generator carries so much of the load which steam source can afford to generate, and diesel-generator carries the remaining. However the diesel-generators load should not be lower than the limit, under which the operation yields a change for worse of the engine efficiency and causes to many kind of troubles. NKK have already applied this equipment to the generating system in the 383rd ship in Shimizu Works and confirmed its effectiveness and practicability. Now the consideration to apply this equipment has been started in many users, and in several ships the fitting has been already decided.
