MHI Receives Order for High-Pressure Gas Supply System for Marine Engines

Mitsubishi Heavy Industries (MHI) has received an order from Hitachi Zosen Corporation for a high-pressure gas supply system enabling use of natural gas as fuel in marine engines. In lieu of conventional heavy oil, the system supplies LNG, injected under high pressure, to the engine.

Delivery of the system is scheduled for the second half of 2016, for installation at Hitachi Zosen’s Ariake Works in Nagasu-machi, Kumamoto Prefecture. After use in gas fueled demonstration testing of a marine diesel test engine, Hitachi Zosen will use the system to provide gas fuel for the marine diesel engines that the company manufactures. The order is the second for this system received by MHI, as well as the first system delivered to Mitsui Engineering & Shipbuilding Co.

With the new system, LNG is pressurized and delivered by liquid pump. The system features a compact configuration and low power consumption. The adoption of a hydraulic driven pump system eliminates the need for a speed reduction mechanism, facilitates variable speed adjustment, and also enables installation in ships where space is limited.
