Watertight doors are special types of doors found on ships that prevent the ingress of water during flooding or accidents.
These doors are used in areas of the ship where there are high chances of flooding.
There are 3 main types of Watertight Doors on a vessel:
- TYPE A - Doors may be left open at all times (except during an emergency).
- TYPE B - Doors should be closed at all times except when personnel are working in an adjacent compartment.
- TYPE C - Doors should be closed at all times except when personnel are passing through the door compartment.
Pan Delta's Water-Tight Door Alarm Panel provides Open/Close Indications and Alarm when a Water-Tight Door is opened.
