Wartsila powers world’s largest cruise liner

Harmony of the Seas in Rotterdam

JUNE 9, 2016 — Helping the world’s largest cruise ship, Royal Caribbean’s Harmony of the Seas, deliver some of the most spectacular activities and amenities ever offered cruise guests is a broad range of Wärtsilä equipment and systems.

The ship was delivered by shipbuilder STX France’s Saint Nazaire, France shipyard on May 12 and Wärtsilä equipment aboard includes 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, is now in commercial operation.

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

Wärtsilä also provided the engines and thrusters to the vessel’s sister ships, the Oasis of the Seas and the Allure of the Seas, underscoring the long term relationship between Wärtsilä and Royal Caribbean International.

“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,” says Fred Danska, Director, Cruise Business, Wärtsilä Marine Solutions.

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 maneuvering, the ship has four Wärtsilä CT3500 transverse thrusters.

The ship’s two Wärtsilä hybrid scrubber systems are the world’s biggest marine exhaust scrubber installation thus far. They feature the latest in exhaust cleaning technology, minimizing sulfur oxide (SOx) emissions and enabling the vessel to comply with emission control regulations around the world. Wärtsilä hybrid scrubber system solutions have the flexibility to operate in both open and closed loop using seawater to remove SOx from the exhaust.

The Wärtsilä NACOS Platinum navigation and dynamic positioning systems are a popular choice of cruise ship operators and feature highly advanced 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 theater.
