How Cruise Ships Float
 
How Cruise Ships Float
Have you ever stood at the dock and watched these great behemoths of the ocean float so effortlessly and wonder to yourself how can something so heavy be able to stay afloat? This article explains how cruise ships are designed to sail you away on a memorable life experience.

GRT is NOT weight!
Firstly, let's de-myth GRT (Gross Registered Tonnage), which is what most people use to describe the size of a ship. It has nothing to do with the actual weight of a ship (in fact a 100,000GRT ship generally weighs around 52,000 tonnes); it's all about the cubic feet of enclosed space that the vessel houses. That's everything from the cargo areas, to public rooms and cabins.

Displacement
To stay afloat you will hear the engineer's talk about "displacement". This is when an object is immersed in the ocean, pushes the water away and takes its place. E.g. for the 100,000GRT cruise ship example above; a 52,000ton ship (in weight) has to displace 52,000tonnes of water before it is fully submerged. If it does – it floats!

Therefore when we're talking about something so heavy we have to make sure that its VOLUME is more than the water that it is replacing; so cruise ships have hulls that are made of lightweight, sturdy material that are obviously hollow and not dense like a bowling ball. It's an amazing fact that the average density of a cruise ship - the combination of the steel and the air - is very light compared to the average density of water. So very little of the ship actually has to submerge into the water before it has displaced the weight of the ship.

Cruise ships generally use watertight round-bottom displacement hulls which are not as fast as Vshaped bottomed hulls that lifts the vessel to the surface of the ocean (like a speed boat), but are more stable and seaworthy, which is what you want when you are holidaying across the sea.
Protection
These days, cruise ships are designed with 'double hulls' and stronger steel than the past. As they are constantly around shallow waters, designers have two hulls, like an inner tube in a tire, to ensure the best protection against potential disasters. Obviously, this is geared to soften clashes with reefs, sandbars, icebergs, etc. and not more solid objects.

Bulkheads
It's important to note here (as we get a little more technical) that hulls are NOT completely hollow; they have bulkheads.

Bulkheads in a cruise ship serve several purposes:

  • Increase the structural rigidity of the ship
  • Divide functional areas into rooms
  • Create water tight compartments that can contain water
  • Most bulkheads & decks are fire-resistant to achieve compartmentalization, an additional protection to stop fire spreading. This is why Muster Stations across the ships are in public rooms that span the length of a cruise ship.
  • Other terminology you may come across
    Some of you may have heard of a keel. This is like a spine that runs from the bow (front of the hull) to the stern (back of the hull). It is traditionally the first part of a ship that is laid down when cruise lines announce the commencement of building their ship, and they then build the hull around it.

    It's the second biggest ceremony of a cruise ship to that of the naming of the vessel, Champaigne bottle and all!

    Hopefully now if the question comes up, you can amaze your friends with your cruising knowledge, especially if any are wondering how a cruise ship floats.
