Wärtsilä LNGPac™

The Wärtsilä LNGPac™ is a complete fuel gas handling system for LNG fuelled ships. It includes the bunkering station, the LNG tank and related process equipment, as well as the control and monitoring system.

Natural gas is becoming increasingly viable as a propulsion fuel in marine applications. Wärtsilä is an acknowledged industry leader in the development of DF engine technology, and offers a complete value chain of systems, solutions, and bunkering arrangements to accelerate the use of environmentally sustainable and economically competitive LNG fuel. Wärtsilä’s unique role as a full systems integrator, with comprehensive in-house knowledge of all the key components of the vessel’s machinery, fuel gas handling system and ship design, has enabled the development of more efficient and elegant solutions.

The Wärtsilä LNGPac™ is a complete fuel gas handling system for LNG fuelled ships. It includes the bunkering station, the LNG tank and related process equipment, as well as the control and monitoring system.

We offer the LNG fuel system both as a standalone product, and as part of a complete propulsion system. Furthermore, Wärtsilä can deliver LNG fuel gas systems for propulsion and power generation for any applicable type of ship or engine.

Standard solution
The standard Wärtsilä LNGPac™ uses an IMO type C LNG storage tank. Bunkering takes place from the bunkering station to the LNG tank via an insulated pipe. The tank connection space contains all the necessary process equipment, and can be either mounted directly to the LNG tank (vacuum insulated tanks) or located remote from the LNG tank (single shell tanks). The main process equipment inside the tank connection space ensures the correct gas temperature for the engines and maintains sufficient pressure inside the LNG tank.

Customised solution
The LNGPac gas supply system can be customised to the needs of each project on a case by case basis by Wärtsilä Fuel Gas Handling’s expert team. We are able to carry out dedicated engineering at the beginning of the project so as to match the specific operational requirements, safety regulations, and the rules of each classification society.

NEW  FEATURES

Integrated Airlock
In the new LNGPac the Airlock is integrated into the Tank Connection Space. This reduces the floor space requirement, increases safety, and makes the installation for the yard much easier.

Integrated Control Cabinet
The Control Cabinet has also been integrated into the Tank Connection Space. This innovation results in a dramatic reduction of interfaces, since the amount of electrical cabling from the Tank Connection Space to the external switchboards can be significantly reduced.

Integrated Gas Valve Unit (GVU)
The functional components of the GVU can be to be installed inside the Tank Connection Space. By combining the LNGPac and the GVU into a single, fully integrated system, considerable space can be saved and a simple ‘plug & play’ solution will save installation time and costs for the yard.

Removal of the heating media skid and pumps
The heating media skid is replaced by an intermediate heating media circuit in the Tank Connection Space. The new circuit requires no pumps and is able to directly utilize the engines’ cooling water. Fewer interfaces are needed and less installation work is, therefore, required. By using fewer less electrical consumers, Wärtsilä is enabling ships to be even more environmentally friendly.
