In the official website of Royal Caribbean International, it is said that there are 2,700 spacious staterooms in the Oasis of the Seas cruise ship. How naval architects who designed the ship arranged the rooms in the superstructure is really amazing. They created a superstructure with a dug out or hollow space in the middle of the superstructure to allow the sun to provide natural lighting to the rooms of the cruise ship optimally - really a smart way of utilizing solar energy without the need of photovoltaic panels. This efficient natural lighting arrangement makes the rooms of the cruise ship looks brighter without consuming a lot of fossil fuel to run electrical generator. At the stern area of the cruise ship, there is a hanging structure. I take the liberty to call it "stern bridge" because it is located at the stern of the Oasis of the Seas cruise ship. We may think that this hanging structure is a bridge that connects the port and starboard superstructures so that people can cross through it. This might be a good guess. I think yes, one of the functions of the hanging stern structure is to allow people walk through it to the other side of the superstructure.

As a matter of fact, in my opinion, from the ship's strength point of view, the addition of the stern bridge is to give more rigidity to the port and starboard superstructures so that they will be more stable. Stable superstructures will not vibrate easily. Vibration is mostly created by the vibrating forces of reciprocal engines inside a ship especially the main engine. Bad designed propellers may also cause vibrations. With the stern bridge constructed behind the ship, the Oasis of the Seas rooms in the superstructure will be more comfortable to the passengers. by Charles Roring
