Wärtsilä Powers the World’s Largest Cruise Ship

Royal Caribbean International’s Harmony of the Seas is now in commercial operation. The ship features Wärtsilä engines, propulsion equipment, navigation and dynamic positioning systems, as well as Wärtsilä CCTV systems and various electrical & automation solutions. With a length of 362 metres the ship, which was built at the STX France shipyard is the world’s largest cruise vessel, and was delivered from the yard on May 12 of this year.
The Harmony of the Seas is powered by four 12-cylinder Wärtsilä 46F engines and two 16-cylinder Wärtsilä 46F engines, featuring best-in-class fuel economy, and outstanding power-to-weight and power-to-space ratios. For effective manoeuvring, the ship has four Wärtsilä CT3500 transverse thrusters.
Wärtsilä has also provided the engines and thrusters to the vessel’s sister ships, the Oasis of the Seas and the Allure of the Seas, thus emphasising the trust and cooperation that exists between the two companies.
