The Urea is decomposed into ammonia and carbon dioxide by the heat from exhaust gas. Natural gas burns far cleaner than petroleum fuel, to there is growing interest in the ship field. We successfully delivered the world’s first 4 stroke Dual Fuel engine for Fixed Pitch Propeller directly couple driven LNG fueled harbor tug boat. It offers high dynamic performance of load following capacity in gas mode, equivalent in diesel mode for tug operation, and safe redundancy as instantly switch between gas & diesel mode.

These ports, where large numbers of these ships are gathered, are located near areas of human activity, and so many concerns over reducing their environmental impact have emerged. For many years, NIIGATA has been providing marine engines, Z-Pellers and control systems as tugboat propulsion systems. We’re now pushing ahead with the development of the “NIIGATA Hybird System”, as a new type of system that is friendly to the environment. Main engine Z-PELLER® Hotel load 6 UJ UJ Interm. shaft Main Engine Shafting Diesel Electric System propulsion system that combines conventional shaft drives with the driving force of the electric motor, so that optimal performance in various types of operations is achieved. Through this arrangement, fuel consumption is drastically reduced. Modern power package integrated propulsion system shall take account of efficiency at saving energy which equal meaning for environmental control eventually. Diesel Electric driven system is really one of solution as the symbol for future aspects of modernized power package. Motor driven application is available to be given satisfaction at any operator.

Conventional system Z-PELLER® system Advantages of the Hybrid System Tugboats, which are designed to produce maximum output during operation, experience fluctuations in their engine-load factor while being piloted. The reason is that they are run at low output while traveling from one place to another or while returning to port. On the other hand, the efficiency of diesel engines drops when load is low, and thus fuel consumption tends to worsen. Hybrid tugboats use a All engines meet NOx emission limit specified by IMO Tier II.
