During the last Seatrade Awards ceremony, STX France and Royal Caribbean International were awarded the fuel efficiency award for their collaborative efforts on the world’s largest and most energy efficient cruise ship, Harmony of the Seas. This award focuses on contributions made to the cruise industry that show real fuel cost savings or enhancements to the commercial usability of new fuels. After one year in operation, the ship has achieved 25% less energy consumption when compared to her sister ship, Allure of the Seas (2010). These incredible results were driven by the collaboration of both the STX France and Royal Caribbean teams, through the thorough evaluation and energy efficiency enhancements of every function on board during the entire ship design, construction and post-delivery processes.

STX FRANCE AND ROYAL CARIBBEAN WIN SEATRADE´S FUEL EFFICIENCY AWARD FOR HARMONY OF THE SEAS

After the firm agreement between STX France and Royal Caribbean was signed in December 2012, the goal when designing Harmony of the Seas was to make it more energy efficient than anything that came before. This goal was achieved through the implementation of a series of innovative R&D solutions, 89 energy efficiency initiatives to be exact, which can be classified in the three major fields below:

·         Hydrodynamics and Propulsion

·         Thermal Energy Recovery

·         Reduction of Overall On Board Energy Consumption

In order to improve the ship’s hydrodynamic performance, STX France’s team redesigned the entire hull and bulb. Additionally, a new air lubrication bubbling system under the hull and a new generation propulsion system contributed to the optimized hydrodynamic performance.

With regards to thermal heat recovery, almost all of the ship’s heating needs are covered by STX France’s patented heat recovery system, which generates heat from the Diesel engine’s cooling system. While this system drastically reduces the need of oil fire boilers, it also produces excess heat which then provides significant free electric power output through a steam-powered turbine.

In addition, STX France and Royal Caribbean developed a combination of energy efficient solutions in various fields on board Harmony of the Seas, including a low energy consumption fresh water production system, an entirely LED lighting system throughout the ship, and HVAC enhancements for cooling plant and ventilation processes.  

In parallel, now that the ship is in operation, STX France and Royal Caribbean still continue to work together to optimize these initiatives. STX France developed a monitoring methodology in order to assist the ship’s operating crew to ensure the energy and emission efficient solutions are in optimal use. Through weekly detailed analyses, on-going advising sessions, and dedicated training, STX France and Royal Caribbean ensure energy and emission efficient operation of Harmony of the Seas, reaching up to 25% energy reduction – which translates to fuel savings – when compared to Allure of the Seas.

Thanks to this close partnership, Harmony of the Seas is setting the new standard for energy efficient cruise ships, not only by reducing operational costs and fuel usage, but more importantly, by minimizing the environmental footprint.

“This award is welcomed by our teams with gratitude. We have worked for several years through our dedicated Ecorizon R&D program to deliver the most efficient and environment friendly ships. The results achieved on Harmony of the Seas, together with Royal Caribbean, are the perfect example of the innovation and engineering capabilities our teams have been striving to accomplish. Both teams are deserving of this exceptional award as a symbol of their great accomplishment,” said Laurent Castaing, General Manager STX France.
