What Is Underneath a Cruise Ship?

By Robert Palmer

Cruise ships are large vessels that are used to transport people to various destinations around the world. They typically have multiple decks, each one with a different purpose. But what lies beneath the decks of a cruise ship?

The first and most obvious layer underneath any cruise ship is the hull. This is the base of the ship, and it protects it from water damage. It is made up of several layers of steel plates that are riveted together in order to provide strength and durability.

This is also where the engine, propellers and other machinery are located.

Below the hull is a series of compartments known as “tanks”. These tanks contain fuel for the engines, fresh water for drinking, grey water for cleaning and sewage, as well as ballast water which helps to keep the ship balanced when navigating through rough seas.

The next layer down consists of plumbing and electrical systems which provide power to all areas of the ship. This includes air conditioning, lighting, lifts (elevators) and other amenities that keep passengers comfortable while on board.

On some ships there may also be a deck or two located below the main decks which house crew cabins or storage spaces for luggage or supplies. On larger ships there may even be a ‘lower hull’ area with additional cabins or rooms for passengers.

Conclusion:

What lies beneath a cruise ship is an intricate system consisting of several layers including its hull which protects it from water damage, tanks that contain fuel and other liquids necessary for operation, plumbing and electrical systems to power amenities on board, as well as potential crew cabins or storage spaces for luggage or supplies depending on the size and type of vessel.
