Floating on Bubbles: Royal Caribbean Brings Energy Efficiency to the High Seas

Harmony of the Seas is the most energy-efficient and technologically advanced cruise ship ever built. Equipped with next-generation technologies, from a multi-stream exhaust gas cleaning system (scrubbers) to an air lubrication system that allows the ship to float on air, with millions of tiny bubbles created under the hull to reduce drag and increase fuel efficiency. Harmony of the Seas raises the bar on environmental stewardship technology.
