Wärtsilä’s LNGPac system reaches 100 orders

Wärtsilä’s Fuel Gas Supply Systems are seeing increasing acceptance, reaching the significant milestone of the 100th order for its LNGPac system since its introduction in 2009 which has played a key role in establishing the viability of liquefied natural gas (LNG) as a marine fuel.

The orders are for two new shuttle tankers being built for Singapore-based AET Tankers which will feature Wärtsilä 34DF dual-fuel auxiliary engines running primarily on LNG fuel, and fitted with LNGPac units.

The system comprises a bunkering station, the LNG fuel tank and related process equipment, as well as the control and monitoring system. The LNGPac fuel system can be offered as a standalone product, or as part of a complete propulsion system.

“A major reason for the global acceptance of LNG fuel for shipping is that Wärtsilä realised at an early stage that more than just a dual-fuel engine and a stand-alone LNG system was needed. LNG fuelled ships require a complete fuel handling system, and the innovative LNGPac system very successfully meets this requirement,” said Mathias Jansson, gm, Fuel Gas Supply Systems, Wärtsilä Marine Solutions.

Since the original introduction of the LNGPac on the chemical tanker Bit Viking in 2011, it has been installed on 12 or more different types of vessel and Wärtsilä has continued to develop the system.

The technology group has, for example, pioneered the utilisation of the cold energy stored in LNG by using it to cool the onboard HVAC and galley system.

Another pioneering achievement has been the development of a compact LNGPac with an integrated gas valve unit (GVU) and airlock. The inline tank connection space for single shell tanks has been developed, as has a dedicated LNG fuel pump based on the well-proven deepwell pump technology.

As the maritime industry moves into a new era of connectivity and digitalisation, Wärtsilä is actively developing more smart features for the LNGPac, such as energy content measurement and real-time gas quality measurement.

The LNGPac system can be customised to the needs of each project on a case by case basis. Dedicated engineering is conducted from the beginning of the project to match the specific operational requirements, safety and classification society requirements.

Its innovative features have made the LNGPac a market leader in fuel gas supply systems. Wärtsilä also offers optimised maintenance agreements, including condition-based monitoring (CBM), for the LNGPac system.
