Wärtsilä Power for New Sto-Ro Freighters
Wärtsilä Corporation has received orders from the Polish shipbuilder Stocznia Szczecinska Nowa for the ship power plants for four new 12 800 tdw multi-purpose Sto-Ro cargo vessels contracted by the Dutch owner Spliethoff's Bevrachtingskantoor BV. Wärtsilä will deliver two 12V46 main engines, two Lips controllable-pitch propellers including Unnet aft seal protection system, two Lips Efficiency Rudders and two Wärtsilä 8L20 diesel generating sets for each of the four vessels. The Wärtsilä 12V46 main engines have a combined output of 25 200 kW, and the generatings sets a combined electrical output of 2720 kW. The Wärtsilä ship power plant will give the vessels a service speed of 22 knots.
When delivered in 2006, the vessels will enter Transfennica services which operates Ro-Ro services between Finland and Estonia, Sweden, Germany, Belgium and the UK. Although designed primarily for carrying forest products and paper, the vessels will be very flexible in their cargo-carrying capacity. Within an overall length of about 205 m, they will have a Ro-Ro capacity of 2800 lane-metres and a container capacity of 660 TEU. They will also have provision for IMO Classes 1 to 8 dangerous cargoes. The vessels will be built to Finnish Ice Class 1A Super.
