MHI receives gas supply system order

LNG Industry,

Mitsubishi Heavy Industries Ltd. (MHI) has announced that it has received an order from Hitachi Zosen Corp. for a high pressure gas supply system enabling use of natural gas as fuel in marine engines.

The system supplies LNG to the engine, which helps reduce emissions of sulfur oxides, nitrogen oxides, and carbon dioxide. Delivery of the system is scheduled for 2H16, for installation at Hitachi Zosen's Ariake Works in Nagasu-machi, Kumamoto Prefecture, Japan. 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. Ltd. (MES). The latest system enables higher gas pressure supply to the engines for enhancement of gas-fuelled performance.

The gas supply system consists primarily of four units: a unit that produces CNG by raising the LNG's pressure and then heating the gas to normal temperature according to engine load fluctuations; a hydraulic unit that serves as the power source; a CNG bottle unit to buffer fluctuations in CNG pressure; and a gas combustion unit that safely disposes of low pressure off-gas and uses the waste heat as a heat source.
