New Year Brings Updated Notification Requirements for Marine Accidents

27th December 2025

Afloat.ie Team

As previously reported on Afloat.ie, the Department of Transport confirmed in April that the Marine Accident Investigation Unit (MAIU) would replace the Marine Casualty Investigation Board (MCIB) as the State’s independent body investigating marine casualties.

The MAIU becomes the designated marine accident investigation authority in the State on 1 January 2026, as legislated for under the Merchant Shipping (Investigation of Marine Accidents) Act 2025.

Section 17 of the Act sets out the statutory obligations for notification of marine accidents, immediately on becoming aware of a marine accident having occurred or commenced, or as soon as practicable thereafter.

Notifications of occurrences of marine accidents should be directed to the MAIU by telephone to +353 1 6768139 (24/7) or by email to [email protected].

For more on these changes, see Marine Notice No 66 of 2025 attached below.
