The Watertight door is placed in a vessel or drill-ship for safety. Normally it is kept open for the passage of crew, passenger and carrying materials. But in case of an emergency such as a fire or a burst of the outer wall of a vessel, the door is to be closed to protect the critical equipment, machine and/or personnel from being flooded or caught in the fire.

The door has an integrated electric and hydraulic system with a power unit consisting of an electric motor and a pump in the door frame itself.

The control of the operation is performed from the control panel in the wheelhouse and by a local lever on the door side.

In an emergency, the operation of door opening/closing is possible by using a hand pump mounted on the power unit.
