The technology comes from the efforts of Celebrity’s parent company Royal Caribbean Group, technology group Wartsila and shipyard Chantiers de l’Atlantique to advance the use of alternative fuels for the cruise industry.

Wartsila will deliver two converted eight-cylinder Wartsila 46F engines to allow the vessel to utilise three fuel sources, including methanol, which will help reduce the use of sulphur oxides, nitrogen oxides and particulate matter. 

The order for the engines was included in the technology firm’s order book in January 2023 and the full scope includes two eight-cylinder 46F engines, two 12-cylinder 46F engines and one 32 engine. 

"As we innovate our ship design and offerings, we’re also focused on equally evolving the fuel and technology landscape that powers them," said Jason Liberty, president and chief executive of Royal Caribbean Group.

"By incorporating tri-fuelled engines, we are ensuring that as alternative, low-carbon-based solutions become more viable, our ships will be ready to adapt and drive the industry forward to a more sustainable and net zero emissions future."
