The product tanker MV Bit Viking has completed the first ever conversion worldwide, of a vessel from HFO to LNG and is now in service operating along the Norwegian coastline . The very low emissions now attainable will qualify for lower Norwegian NOx emission taxes. The Bit Viking has a very high safety specification, delivered in 2007, the double hulled product tanker of 24,783 dwt has an LOA of 580 ft (177 m) and a beam of 82 ft (26.3 m). The conversion required a major rebuild of the engines from Wärtsilä 6L46B to 6L50DF engines with output of 7,460 hp (5,700 kW). Although having the same stroke as the old engine, required increasing the cylinder bores from 460 mm to 500 mm and replacing most of the engine parts. Safety analysis and approval was undertaken by Germanischer Lloyd (GL) classification society. [More]

LNG storage tanks on ships

Using LNG as a fuel can offer a practical and economic solution for the ship operator. Operating a ship using a fuel in a gas state requires integration of the entire chain from shipside bunkering, storage, conditioning and delivery to the engine and its conversion into power. Within a period of a few weeks, builders of dual fuel engines Wärtsilä and MAN have published their own solutions to this question. Both systems allow the ship owner to deliver/complete dual fuel with LNG propulsion system from one manufacturer and have the reassurance that the entire system is compatible including bunkering and on board storage.
