Wärtsilä LNGPac
The design philosophy of LNGPac is based upon safety and simplicity. LNGPac is a complete system that includes the bunkering station, LNG tank and tank room compartment, process skid, glycol-water heating unit, and the control and monitoring system.
Natural gas is becoming increasingly viable as a propulsion fuel in marine applications. Wärtsilä is a leader in developing dual-fuel engine and LNG fuel system technologies that have enabled this change. We offer the LNG fuel system on its own, as well as complete propulsion systems. Wärtsilä Oil & Gas Systems can deliver LNG fuel gas systems for propulsion and power generation for any applicable types of ship or engine, both low pressure and high pressure.
Standard solution
Bunkering takes place from the bunkering station from where LNG is transferred into the LNG tank. The LNG tank room compartment is mounted directly on the LNG tank. The tank room contains all the piping penetrations through the tank shell, as well as all heating media connections to the LNG evaporators.
The process skid includes all the connections and valves between the tank and the Pressure Build-up Evaporator (PBE), and between the tank and the Main Gas Evaporator (MGE), together with the evaporators themselves.
The evaporators are heated by glycol-water that is circulated within a glycol-water heating unit.
Customised solution
LNGPac gas supply system can be customized to the needs of each project on a case to case basis by Wärtsilä Fuel Gas Handling expert team. Some dedicated engineering has to be performed at the beginning of the project matching the specific operational requirements, safety regulations, rules of each classification society qualifying the vessel.
