Wartsila To Provide Power On Unique Icebreaking Tankers
Wartsila Corp. diesel engines were selected to power a pair of 106,000-dwt Aframax icebreaking tankers of the revolutionary new double-acting concept.
The two tankers were contracted by the Finnish energy group Fortum Oil & Gas for building at Sumitomo Heavy Industries Ltd. in Japan with delivery by mid 2002.
Each ship will be powered by a 22.9 MW diesel-electric plant supplying all propulsion and ancillary power requirements.
Each plant includes two Wartsila 9L38B diesel engines each of 6,320 kW output at 600 rpm, two Wartsila 6L38B diesel engines each of 4,220 kW and one Wartsila 6L26 diesel engine of 1,860 kW at 900 rpm. Electric propulsion is provided by a single 16 MW podded drive.
These icebreaking tankers will be employed between the North Sea and refineries in the northern Baltic ports of Porvoo and Naantali, which experience some 110-115 days of ice each year.
They are thus being built to Ice Super class and will follow a revolutionary Double Acting Tanker (DAT) concept developed by the Arctic Technology Center of Kvaerner Masa-Yards in Helsinki.
In the DAT concept, the ship is designed for running astern as an icebreaker, and ahead in open water. Thus the ship's stern is designed for optimum performance when breaking ice, making best use of the bow propeller effect to create a strong lubricating flow of water reducing friction between the hull and ice.
The forebody is designed to be more efficient in open water than a conventional icebreaking hull design.
