Wärtsilä LNGPac™ is a complete fuel gas handling system for LNG fuelled ships and includes the bunkering station, LNG tank and related process equipment as well as the control and monitoring system.
The LNG fuel system can be offered as a standalone product, as well as a part of a complete propulsion system. Wärtsilä can deliver LNG systems for propulsion and power generation for any applicable types of ship or engine.
The Wärtsilä LNGPac™ system is based on IMO type C LNG storage tank with either double walled vacuum or single walled polyurethane insulation. Bunkering takes place from the bunkering station to the LNG tank via an insulated pipe. All necessary process equipment is installed in a separate unit which can be either mounted directly to the LNG tank or placed remotely from the LNG tank. The main process equipment ensures correct gas temperature and pressure for the engines and other gas consumers.
The LNGPac system can be customised to the needs of each project on a case to case basis. Dedicated engineering is conducted from the beginning of the project to match the specific operational requirements, safety- and classification society requirements.
Wärtsilä can deliver LNG systems for propulsion and power generation for any applicable types of ship or engine, either as a standalone product or as a part of a complete propulsion system.

Our innovative features have made the LNGPacTM a simple plug and play solution with the following benefits:
The Airlock can be integrated with the LNGPac™. This reduces the floor foot print, increases safety aspects and makes the installation for the yard much easier.
INTEGRATED CONTROL CABINET
The Control Cabinet can be integrated with the LNGPac™. This innovation results in a dramatic reduction of interfaces since the electrical cabling from the LNGPac™ to the external switchboards can be reduced to only a few cables. LNGPac automation can be connected to the Wärtsilä engine digital ecosystem for global maintenance support during complete vessel life cycle. One supplier for automation design, project execution, commissioning work and services - reducing project risk and minimizing delays in communication.
INTEGRATED GAS VALVE UNIT (GVU)
The functional components of the GVU can be integrated as part of the LNGPac™. By combining the LNGPac™ and the GVU into a single system, considerable space can be saved. The solution will also save installation time and costs for the yard.
REMOVAL OF THE HEATING MEDIA SKID
New evaporator type allows the engine LT-water to be directly connected to LNGPac without the need of an intermediated heating media circuit. This leads to fewer interfaces and installation work is required.
MAINTENANCE ORIENTED DESIGN
LNGPac™ design focuses on enabling safe service and maintenance of all core equipment related to the operational functionality of LNG bunkering and gas consumption without emptying the tank.
