Repeat Orders for Wärtsilä 6L64 Engines

Friday, May 16, 2003
Wärtsilä Corporation has received repeat orders for the Wärtsilä 64, the company’s powerful medium-speed diesel engine.

Four Wärtsilä 6L64 engines were ordered at the beginning of this year by the Polish shipbuilder Stocznia Szczecinska Nowa Sp.z o.o. as main engines for four 18,900 tdw multi-purpose vessels recently contracted by the Dutch shipowner Spliethoff Bevrachtningskantoor B.V.

These vessels, which are repeats of the 10 S-class vessels delivered in 1999-2000 to the same owner, four of which were built by Stocznia Szczecinska in Poland, three by Mitsubishi Heavy Industries Ltd. , and three by Tsuneishi Shipbuilding Co. Ltd in Japan. The latest four newbuildings are expected to be delivered between April 2004 and April 2005.

The Wärtsilä 6L64 engines will each develop a maximum continuous power of 12,060 kW at 333 rpm. The engines will be built at Wärtsilä's Trieste factory in Italy.

The engine is coupled to the reduction gear through an elastic coupling without a clutch. For each vessel, Wärtsilä is also supplying a Lips controllable-pitch propeller together with the shafting and remote control system, as well as a power take-off (PTO) generator.

The scope of supply from Wärtsilä includes ancillary equipment for fuel oil, lubricating oil, cooling water and starting air systems. The lubricating oil and cooling water pumps, oil cooler and filter are built on the engines.

The Wärtsilä 64 engines are delivered with E.I.A.P.P. certificate as complying with the IMO NOx emission limit. Owing to the high engine flexibility (twin injection pump) there is the possibility to adjust the fuel injection timing according to engine load and run to a best efficiency profile when sailing at cruise speed, or according to best emission profile when operating in port or coastal areas.
