Built for a purpose
- Builder / location
- STX France, Saint-Nazaire, France
- Original role
- Oasis-family cruising
Why it was built
Harmony of the Seas was the first ship delivered under the Saint-Nazaire programme contracted in December 2012. The yard handed it over in May 2016. It brought the Oasis-family arrangement to this French building site, including an internal promenade and planted park.
A city-like arrangement at sea
The interesting engineering question is not simply how to make a hull longer. It is how to support extensive accommodation around open spaces while connecting passengers with restaurants, activities and services. A ship of this type also needs large networks for ventilation, water, electricity, food handling and waste. Our shipbuilding article follows how those networks are integrated into blocks before delivery.
What the figures mean
The shipyard uses rounded figures for its series description, while the directory records vessel-specific measurements from the linked specification source. Small differences should not be read as a reconstruction of the hull. Check whether a source measures waterline beam or maximum width, and whether passenger capacity means two guests per cabin or the maximum permitted occupancy.
