A third environmentally friendly Icon-class ship is to be built for Royal Caribbean International.

The latest vessel to be powered by liquefied natural gas (LNG) is set for delivery in 2025.

The first two Icon-class ships are due to enter service in 2022 and 2024.

All three will use clean energy and have “breakthrough” ship design.

The initial pair of ships were announced at 200,000 tons with a capacity for 5,000 passengers.

The line previously indicated that it would consider deploying an Icon-class ship out of Southampton once Brexit is sorted out.

The latest order is contingent on financing but no value was revealed by parent company Royal Caribbean Cruises.

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

“We’ve designed a class of ships powered by liquefied natural gas that leverages the latest, environmentally-friendly applications.

“We believe that innovative shipbuilding can reduce our carbon footprint and boost energy efficiencies to help to build a cleaner future.”

Royal Caribbean International president and CEO Michael Bayley added: “These are exciting times for Royal Caribbean, and we have an incredible partner in [shipyard] Meyer Turku to bring to life now three vessels of what will be a remarkable class of ships.”

“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.”
