W a r t s i l a Engines To Power Queen M a r y 2

Wartsila Corporation will deliver four Wartsila 46 EnviroEngines totaling 67.2 MW power output for Cunard Line's new luxury transatlantic liner, Queen Mary 2. These engines will incorporate the latest common-rail fuel injection technology for operation without any visible smoke.

Due for delivery in late 2003 by the French shipbuilder Chantiers de l'Atlantique in Saint Nazaire, Queen Mary 2 will be the world's largest passenger vessel.

Measuring 1,131 x 131.2 ft. (345 x 40 m) and drawing 32 ft. (10 m), the 150,000 grt liner will have a maximum speed of about 30 knots. Electrical power for propulsion and all shipboard services will be generated by a 115.5 MW combined diesel- and gas turbineelectric power plant. Propulsion will be by four electrically driven podded drives, two fixed and two azimuthing.

The four Wartsila 16V46 Enviro- Engines will be manufactured at Wartsila's Turku factory in Finland. They are due to be shipped in June 2002. The engines will each have a maximum continuous output of 16,800 kW (22,840 bhp) at 514 rpm. For redundancy, the diesel generating sets will be housed in two separate engine rooms on board the Queen Mary 2.

The Wartsila EnviroEngine arose from a joint project between Carnival Corporation, the parent company for Cunard Line, and Wartsila Corporation to develop a new "earth-friendly" power system.

The Wartsila 46 EnviroEngines use an electronically-controlled common rail fuel injection system which enables injection pressures to be kept sufficiently high at all engine loads and speeds — even at the lowest levels - to achieve clean combustion with no visible smoke emissions.
