The world’s largest cruise ship has taken to the waves ably assisted by Finnish marine engine specialist, Wärtsilä.

Royal Caribbean International’s Harmony of the Seas recently completed her maiden voyage from Southampton to Barcelona powered by Wärtsilä engines, propulsion equipment, exhaust scrubber systems, Wärtsilä NACOS Platinum navigation and dynamic positioning systems, as well as Wärtsilä CCTV systems and various electrical & automation solutions.

Fred Danska, director of cruise business at Wärtsilä Marine Solutions, said: "Wärtsilä congratulates both Royal Caribbean and STX France on this milestone delivery of the world's largest cruise ship.”

“We are proud to have been selected to provide a comprehensive scope of Wärtsilä solutions and we wish good luck and success for the vessel throughout its lifecycle," he said.

The 362m vessel, built at the STX France shipyard in Saint-Nazaire, is powered by four 12-cylinder Wärtsilä 46F engines and two 16-cylinder Wärtsilä 46F engines. For effective manoeuvring, the ship has four Wärtsilä CT3500 transverse thrusters.   

The two Wärtsilä hybrid scrubber systems represent the world's biggest marine exhaust scrubber installation so far. They feature the latest in exhaust cleaning technology thus minimising sulphur oxide (SOx) emissions and allowing the vessel to comply with emission control regulations around the world.

The Wärtsilä NACOS Platinum navigation and dynamic positioning systems feature integrated navigation technology. Other electrical and automation solutions have been provided by Wärtsilä Funa for this vessel, including a house light dimming system for all public venues, a dimming system for the suites, and a low resolution LED wall for the theatre.

The Harmony of the Seas has also been included in a service agreement between Wärtsilä and Royal Caribbean covering technical management and monitoring under Wärtsilä Genius services.
