Harmony of the Seas is one of the biggest cruise ships ever built. Sixteen passenger decks, a quarter of a million gross tons, and for two years the largest cruise ship on Earth. But the resort you see on the surface is only a third of the story. Below the pools and the park lies a floating machine engineered to keep nine thousand people alive in the middle of the ocean.
In this full tour, we go from the shipyard in Saint-Nazaire, France, where the ship was assembled from giant prefabricated steel blocks, all the way down to the engine rooms beneath the waterline. Along the way we answer the questions the brochures skip. How does a 100,000-ton steel hull float instead of sinking? Why does a ship this tall not tip over? Where does the electricity come from when the nearest power line is an entire coastline away? How do three rotating Azipods steer a quarter-million-ton vessel into port without a single tugboat?
We break down the diesel-electric power plant that runs an entire city, the ballast tanks that fight the ocean's roll, the closed-loop waterslides, the free-surface physics that has capsized lesser ships, and the military-scale operation that feeds and supplies a town at sea. From the keel up, this is how one of the largest cruise ships in the world actually works.
