Weathertight/Watertight Doors

Watertight doors are special types of doors found on ships that prevent the ingress of water from one compartment to another during flooding or accidents and therefore act as a safety barrier.

It limits the spread of water inside the vessel. These doors are used onboard in many ships such as in the fore and aft passageways underdeck and in engine room bulkheads leading to shaft tunnels in container vessels, large passenger ships, offshore vessels, oil exploration vessels. They are used in areas where chances of flooding are high. Areas such as engine room compartments and shaft tunnels and some of such places.

To make it simpler, a watertight door can prevent the passage of water in both directions when subjected to a head of water i.e it can withstand water pressure from both sides. They are designed to withstand continuous submersion and are therefore located below waterline like shaft tunnels, ballast tanks, bow thruster compartments etc. all openings below the waterline has to be watertight.

Weathertight doors, on the other hand, is designed to withstand brief submersion. They are located above the waterline and can withstand the weather condition as found offshore which means from the outside.
