May 16, 2003 Repeat orders for Wartsila 64 Four Wartsila 6L64 engines have been ordered by Polish shipbuilder Stocznia Szczecinska Nowa Sp.z o.o. as main engines for four 18,900 dwt multi-purpose vessels recently contracted by the Dutch shipowner Spliethoff Bevrachtningskantoor B.V. These vessels are repeats of the ten S-class vessels delivered in 1999-2000 to the same owner. Four of these vessels were built by Stocznia Szczecinska in Poland, three by Mitsubishi Heavy Industries Ltd., and three by Tsuneishi Shipbuilding Co. Ltd in Japan. The four latest newbuildings are expected to be delivered between April 2004 and April 2005. The 6L64 engines will each develop a maximum continuous power of 12,060 kW at 333 rev/min. The engines will be built at Wartsila's Trieste factory in Italy. The engine is coupled to the reduction gear through an elastic coupling without a clutch. Wartsila is also supplying a Lips controllable-pitch propeller for each vessel along with the shafting and remote control system, as well as a power take-off (PTO) generator. The scope of supply from Waertsilae 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 shipowner's existing 10 similar 6L64 installations have accumulated a total of more than 161,800 running hours. All engines are running according to an average load profile which is close to 85% MCR. The component experience is very good and cylinder liners, bearings and piston ring expected lifetimes can be easily reached and even doubled (liner and bearings). The Wartsila 64 engines are delivered with E.I.A.P.P. certificate as complying with the IMO NOx emission limit. Owing to the engines high 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 cruising speed, or according to best emission profile when operating in port or coastal areas. The flexibility of the Wartsila 64 installation gives the shipowner the possibility to run in the most severe conditions (all vessels are built to ice class) without an engine performance penalty.
The Wartsila 64 engine with its PTO alternator and reduction gear driving a controllable-pitch propeller is a dynamic installation that provides the shipowner with the following benefits: |
