Compartmentalisation of a ship, to reduce floodability Parts of a water-tight compartment. Floodability is the susceptibility of a ship's construction to flooding.It also refers to the ability to intentionally flood certain areas of the hull for damage control purposes, or to increase stability, which is particularly important in combat vessels, which often face the possibility of serious hull ...
That is, instead of assessing the ship for one compartment failure, a situation where two or even up to three compartments are flooded will be assessed as well. This is a concept in which the chance that a compartment is damaged is combined with the consequences for the ship, resulting in a damage stability index number that has to comply with ...
The centerline position code is zero for a compartment on the ship's centerline, odd numbers for compartments entirely to starboard of the centerline, and even numbers for compartments entirely to port. For compartments sharing the same deck and forward frame, the first two parts of the code are identical, and the third part of the code is ...
Cross section of a vessel with a single ballast tank at the bottom. A ballast tank is a compartment within a boat, ship or other floating structure that holds water, which is used as ballast to provide hydrostatic stability for a vessel, to reduce or control buoyancy, as in a submarine, to correct trim or list, to provide a more even load distribution along the hull to reduce structural ...
locking off the damaged area from other ship's compartments; blocking the damaged area by wedging a box around a tear in the ship's hull, putting a band of thin sheet steel around a tear in a pipe, bound on by clamps. More complicated measures may be needed if a repair must take the pressure of the ship moving through the water. For example:

Even more recent is the concept of canting keels, designed to move the weight at the bottom of a sailboat to the upwind side, allowing the boat to carry more sails. A twin keel has the benefit of a shallower draft and can allow the boat to stand on dry land.
Pilots of Boeing 777s are also able to get some shut eye in hidden compartments in the front of the plane. Not as nice as a hotel room, but it gets the job done.
