Allure of the Seas is primed to make her maiden voyage later this month and the Wärtsilä engines that are installed in Allure of the Seas, are what power Royal Caribbean's newest ship. In addition, the Wärtsilä engines have common-rail systems, which provide lower fuel consumption and reduced emissions, giving smokeless operation at various engine loads.
The brand new largest cruise ship in the world sports six Wärtsilä 46 engines, including three 12-cylinder and three 16-cylinder Wärtsilä 46 engines in V-configuration, and Wärtsilä 7500-horsepower bow thrusters with a combined power output of some 20 MW that make the vessel easy to maneuver.
Royal Caribbean and Wärtsilä have a history of cooperation going back 40 years and the last ship in Royal Caribbean's line to feature the enginers is Allure of the Seas' sister ship, Oasis of the Seas.
