Wärtsilä’s LNGPac fuel gas supply system has been chosen for installation to two new shuttle tankers for Singapore-based AET, marking the 100th order of the systems.
The tankers will feature Wärtsilä’s 34DF dual-fuel auxiliary engines, which will run primarily on liquefied natural gas (LNG) fuel and will be fitted with LNGPac units.
Wärtsilä LNGPac 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.
Since the first installation of LNGPac on the Tarbit-owned chemical tanker, Bit Viking, in 2011, LNGPac has been developed to use cold energy that is stored in LNG to cool the onboard HVAC and galley system.
It has also been integrated with a gas valve unit (GVU) and airlock and features additional smart technologies, such as energy content measurement and real-time gas quality measurement.
Each LNGPac system can be customised to the needs of each project on a case by case basis. Dedicated engineering is carried out at the beginning of the project to match the specific operational requirements, safety, and classification society requirements of each vessel.
Mathias Jansson, General Manager, Fuel Gas Supply Systems, Wärtsilä Marine Solutions said: “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.”
Wärtsilä also offers optimised maintenance agreements, including condition-based monitoring (CBM), for the LNGPac system.
