The 25,000 dwt product tanker Bit Viking was the first vessel ever to undergo a conversion by Wärtsilä from Heavy Fuel Oil (HFO) to Liquefied Natural Gas (LNG) operation.
After the conversion the vessel qualifies for lower nitrogen oxide (NOX) emission taxes under the Norwegian NOX fund scheme.
In 2011, the first ever marine conversion of Wärtsilä 46 engines to Wärtsilä 50DF dual-fuel engines was carried out on the product tanker Bit Viking, owned by Tarbit Shipping of Sweden. It also represented the first Wärtsilä
50DF dual-fuel marine installation with mechanical propulsion.
By operating on LNG, the Bit Viking is one of the most environmentally friendly product tankers in the world. Its emissions of CO2 have been reduced by some 25%, while emissions of particulates have also been dramatically lowered, and NOX emissions are
significantly cut. When using LNG fuel, SOX emissions are eliminated entirely.
– This is also a major benefit for our customer who operates along the Norwegian coast, says Anders Hermansson.
