Royal Caribbean International has ordered a third Icon-class cruise ship from the Meyer Turku shipyard.

The new LNG-powered, 200,000-gross ton mega ship will be delivered in 2025, according to a statement.

The ship will join its two sister ships – to be delivered in 2022 and 2024, respectively, according to Cruise Industry News.

The Icon-class ships will be slightly smaller than the Oasis-class and will be delivered from 2022 onwards

“We are thrilled to announce the newest addition to our Icon-class fleet that affirms our commitment to clean-power technologies at sea,” said Richard Fain, Chairman and CEO, Royal Caribbean Cruises.

“We’ve designed a class of ships powered by liquefied natural gas that leverages the latest, environmentally-friendly applications,” he added. “We believe that innovative shipbuilding can reduce our carbon footprint and boost energy efficiencies to help to build a cleaner future.”

The ship order builds upon a previously-placed order with the same shipyard for two Icon-class ships. At 200,000-gross tons, they will sit between the Oasis-class (currently the largest cruise ships ever built at more than 225,000-gross tons) and the 168,000-gross ton Quantum-class.

Few details about the new class of cruise ship has been announced, but Royal Caribbean has indicated they’ll likely carry around 5,000 passengers.

Michael Bayley, President and CEO, Royal Caribbean International, says they will be ‘a game-changer’.

“These are exciting times for Royal Caribbean, and we have an incredible partner in Meyer Turku to bring to life now three vessels of what will be a remarkable class of ships,” he said.

“Building on our vision with the addition of a third order is a testament to our confidence in the innovative design and energy-efficient technology and engineering that will, without a doubt, make Icon class a game changer,” he added.

“We are very thankful to Royal Caribbean for their confidence in the Icon ship design and our ability to build such an exceptional ship even before the first Icon is delivered,” said Jan Meyer, CEO, Meyer Turku.

Meyer Turku is the same shipyard that built Royal Caribbean’s Voyager-class cruise ships between 1999 and 2003. At more than 137,000-gross tons they were at the time the largest cruise ships ever built.

According to the unofficial Royal Caribbean Blog, the first Icon-class cruise ship is likely to be called Icon of the Seas, although this has not been confirmed by Royal Caribbean itself.

It would follow the cruise line’s historical tradition of naming the lead ship in each eponymous class. The lead Oasis-class ship is Oasis of the Seas, the lead Quantum-class ship is Quantum of the Seas and so on.
