Report a marine accident

Report a marine accident by calling the MAIB reporting line on +44 (0)23 8023 2527 and then completing the accident report form.


Accidents, including serious injuries, should be reported to the MAIB by the quickest means possible. This is so that the MAIB can decide whether to investigate the accident without delay, and prevents evidence of all types being lost or decaying.

To report an accident you should phone the MAIB’s dedicated accident reporting line on +44 (0)23 8023 2527 which is monitored 24 hours a day. After this initial notification you can expect to be asked to complete the accident report form (ARF).
