Report an accident

To fulfil its primary role of improving safety of life at sea, it is essential that the MAIB investigates accidents immediately, before vital evidence decays, is removed or is lost.

To enable this the law requires that accidents, including major injuries, be reported by the quickest means possible and the MAIB has a dedicated reporting line for this purpose – 023 8023 2527 from within the UK or +44 23 8023 2527 if you are outside the UK. This line is manned 24 hours a day.

Having reported the accident by telephone, a completed incident report form should be emailed or faxed to +44 23 8023 2459 as soon as possible. PLEASE NOTE: the MAIB email account and fax machine are only monitored during normal office hours.

Serious injuries, those resulting in incapacitation for longer than three days that are not major injuries, must be investigated by the vessel’s master and owners. The findings of this investigation must then be reported to the MAIB within 14 days, using the incident report form.

The law does not require hazardous incidents to be reported. However, the MAIB encourages owners, masters and skippers to report them using the incident report form or the dedicated reporting line. Hazardous incidents often teach us lessons that are every bit as relevant as those arising from accidents.
