History of the business TOP

The Energy and Marine Machinery business started manufacturing marine steam turbines in 1907 (Meiji 40) as the marine machinery department of »¨ÃÛÖ±²¥app Dockyard. Since then, our business has branched out while expanding our product areas from the sea to land. In our energy sector, we produce industrial gas turbines, as well as other equipment such as gas engines, natural gas compression facilities, and steam turbines for home power production. In our marine machinery sector, we have produced various marine propulsion devices, including marine diesel engines that have over 100 years of history.

  Completion of 7.8 MW power-generating gas engine with world-class power generating efficiency

  As environmental regulations became stricter from the 2000s, there was a shift from diesel engines that use liquid fuel to gas engines fueled by natural gas, significantly reducing the emission of harmful substances such as CO₂, NOx, and particulate matter. During this transition, our company developed a Green Gas Engine with the world’s highest class power generation efficiency. With its superior power generating efficiency and environmental performance, the Green Gas Engine went on to capture the top market share in Japan.

  The L30KG marine gas engine becomes first Japanese-made engine to acquire type approval from the DNV in Norway

  In anticipation of the International Maritime Organization (IMO) regulations on CO₂, NOx, and SOx emissions, we utilized technology from the Green Gas Engine to develop the L30KG marine gas engine. This engine is the first domestically-produced gas engine to receive type approval from Det Norske Veritas (DNV) in Norway. The L30KG achieves performance that significantly exceeds the NOx Tier III regulations without the need for special equipment such as denitrification devices. It also significantly reduces CO₂ and SOx emissions compared to diesel engines, allowing it to contribute to the construction of vessels that comply with various environmental regulations.
