The Marine Safety Forum draws lessons learned an incident where an individual was found trapped between a sliding hydraulic watertight door and its frame.
What happened
On 2nd April 2025, an individual was found trapped between the sliding hydraulic watertight door and the door frame. He was unconscious and not breathing. He was brought to the sick bay and assessed with no signs of life. The Incident Management Team was activated, and topside medical supported the response. Immediate care was provided for the deceased, their family, and the crew onboard. An incident investigation is underway.
Although the actual causes have yet to be determined, the purpose of sharing this alert is to facilitate reflective discussions with vessel marine crews and interested parties on the dangers posed by watertight doors.

Watertight door safety – Awareness
Function:
-
Watertight doors prevent water passage between compartments, maintain buoyancy and stability, and enhance safety by limiting water movement during emergencies.
-
Typically located in underdeck areas prone to water ingress and found on various types of ships and vessels, including container ships and offshore vessels.
Operation:
-
Two main types: hinged and sliding doors.
-
Powered watertight doors can be operated locally, remotely from the bridge, or set to automatic closure mode.
-
Powered watertight doors are extremely heavy and powerful.
Further guidance can be found in MGN 35 (M+F) Amendment 2 and COSWP (11.6)
Lessons learned
-
Provide thorough familiarisation and training in the operation of all power-operated doors, including details of their hazards. Training should include review of written procedures and hands-on operational instruction.
-
Ensure the planned maintenance system is followed for routine inspection and maintenance of watertight doors.
-
Always fully open a watertight door before passing through.
-
Use audible alarms and visible warning lights to show door status and warn personnel nearby.
-
Ensure all crew members who may use the doors:
a. Know what type of control system is fitted.
b. Are well trained in the correct operating procedure.
c. Fully appreciate the crushing power of watertight doors.
