Subdivision of a ship s hull into watertight compartments is called compartmentation. A compartment is a portion of the space within a ship defined vertically between decks and horizontally between bulkheads it is analogous to a room within a building and may provide watertight subdivision of the ship s hull important in retaining buoyancy if the hull is damaged.

They can be find in engine room compartments bow thruster compartments etc. Not more than one watertight door is allowed per watertight bulkhead. The doors are used to divide vessels into watertight compartments. The closure between two compartments below the waterline will typically be watertight it is essential that these compartments are resistant against great water pressure as is the case during a major water leakage.

Also the doors should be checked before leaving the port. The mechanical gears required for manual operation of these doors must be located outside the machinery spaces.
