BEHIND THE PARTICULARS

Built for a purpose

Builder / location: Meyer Turku, Turku, Finland
Original role: Large resort-style cruise ship
Power and propulsion: LNG-capable power plant; electric propulsion

Why it was built

Icon of the Seas introduced a new Royal Caribbean ship class built around the holiday itself. Its public spaces, accommodation and attractions occupy an enormous enclosed volume. That is why gross tonnage is more useful than length alone when comparing it with a tanker: the two hulls solve very different commercial problems.

A Finnish build, an Atlantic delivery

The ship was delivered from Turku in late 2023. Its first revenue voyage departed Miami on 27 January 2024. That construction-to-service sequence took a vessel assembled in the Baltic into the Caribbean cruise market. Those are documented milestones, not a claim about its present location.

Reading the machinery

Meyer Turku identifies LNG as part of the ship’s energy system. Fuel and propulsion are separate ideas: fuel supplies energy, generators produce electricity, and electric motors turn the propulsors. The same electrical plant must also support the considerable hotel demand. Compare this arrangement with the mechanical drive of a conventional cargo ship in our propulsion guide.
