LNG Fuel Gas Management System

Engineered exclusively for MAN GI engines, the HP FGSS, part of a broader LNG Fuel Supply System, utilizes PVU technology to elevate LNG pressure beyond 300 bar. This advanced system accomplishes approximately 90% lower methane emissions compared to MAN GA engines. The LP FGSS variant is specifically designed for Otto-cycle gas engines, operating at sub-16-bar pressures. For optimal gas management, the system seamlessly integrates both a gas combustion unit (GCU) and a gas boiler to efficiently process boil-off gas (BOG).
