(HELSINKI, Finland) — The technology group Wartsila's fuel gas supply systems have passed a milestone with the 100th order being booked. Two new shuttle tankers being built for Singapore based AET Tankers will feature Wartsila 34DF dual-fuel auxiliary engines running primarily on liquefied natural gas (LNG), and fitted with LNGPac units. This contract brought the total number of orders received for this system to 100. Introduced in 2009, the Wartsila LNGPac has played an important role in establishing the viability of LNG as a marine fuel. 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. The first LNGPac installation was for the chemical tanker Bit Viking owned by Swedish operator Tarbit.
