Automatic water tight door operating gear

Automatic operating gear allows the remote operation of watertight doors. These are fitted on many vessels including passenger ships.
In the event of fire or flooding, operation of switches from bridge/fire control area sends a signal to an oil diverter valve. Oil from a pressurised hydraulic system is sent to a ram moving the door.
The door may also be operated locally by a manual diverter valve. In addition, in the event of loss of system pressure the door may be operated by a local manual hand pump
remote door position indicators are fitted as well as were appropriate alarms to indicate operation.
