Swedish owner to convert tanker to LNG fueled propulsion
Tarbit Shipping of Sweden is to convert a product tanker to LNG-fueled propuslion. It has signed a turnkey contract that will see Wärtsilä convert the ship's two main engines and supply it with a Wärtsilä LNGPac system for the storage of LNG onboard. This is the first order for a Wärtsilä LNGPac system.
The 25,000 dwt product tanker Bit Viking is operated by Statoil along the Norwegian coastline, and the conversion will enable the vessel to qualify for lower NOX emission taxes under the Norwegian government's NOX fund scheme
"By carrying out this large-scale conversion project, and equipping the vessel with the new Wärtsilä LNGPac system, the ship's emissions will be significantly reduced. This obviously is of tremendous benefit to the environment, and is in line with both the letter and the intent of the Norwegian government's NOX fund initiative," comments Torkel Hermansson, Managing Director of Tarbit Shipping.
The contract covers the conversion of the ship's two main engines to gas-fueled propulsion, all adjustments to the ship's systems necessitated by the conversion, the updating of the vessel's classification certificate, and the supply and installation of the Wärtsilä LNGPac system, including two 500 cu.m LNG storage tanks. Wärtsilä is responsible for carrying out everything involved in the contract, and the schedule calls for completion by June 2011.
Delivered in 2007 by China's Shanghai Edwards shipyard, Bit Viking has twin screw propulsion and is built with double engine rooms, propellers, steering gears, rudders and control systems. Each screw currently powered by a 6-cylinder in-line Wärtsilä 46 engine running on heavy fuel oil (HFO). The conversion involves changing these to 6-cylinder in-line Wärtsilä 50DF dual-fuel engines that will operate on LNG.
The Wärtsilä LNGPac is a total system developed by the company to enable the safe and convenient storage of the gas fuel onboard ship, and to facilitate bunkering operations.
"This conversion contract represents a big step for Wärtsilä", says Björn Ullbro, Managing Director at Wärtsilä Sweden in Göteborg, where the conversion work will be performed. "The 'Bit Viking' will be fitted with the first ever Wärtsilä 50DF engine with mechanical drive and is, therefore, a breakthrough for both the company and for the industry as a whole. Furthermore, it shows Wärtsilä's commitment to adding value to its customers' operations throughout the lifecycle of their installations."
