JULY 29, 2013 — Daewoo Shipbuilding & Marine Engineering and MAN Diesel & Turbo have signed an agreement related to the DSME high pressure-fueled gas supply (HP-FGS) system.
Pump-based DSME HP-FGS system needs less space and power than compressor-based alternatives
Under the agreement, MAN Diesel & Turbo will use DSME HP-FGS system patents and licenses for its LNG propulsion based commercial vessel projects.
Following the confidential agreement between two companies, specific license fee and other details of the contract have not been disclosed.
Engines built under MAN Diesel & Turbo license have an 80 percent share of the marine two stroke market and its ME-GI engine is the first ( and so far only) LNG-fueled two stroke engine available for commercial vessels.
When the ME-GI engine was first introduced, the drawbacks of using a high pressure gas compressor system for the FGS system included the power and space requirements.
However, the DSME high pressure pump-based FGS system provides radical improvements in power and space efficiency.
DSME introduced FGS systems in 2007 and holds international intellectual properties on the technology. In May 2011, DSME completed HP-FGS system integration testing with ME-GI engine at the MAN B&W Copenhagen research center.
DSME is providing its FGS system to General Dynamics NASSCO shipyard for TOTE‚Äôs two 3,100 TEU world first LNG-powered containership.
