The MCIB commenced investigations into 11 marine casualties in 2022, of which eight occurred in 2022, two in 2021, and one in 2020. No lives were lost in any of the marine casualties under investigation.

A further 74 incidents were considered by the Board which involved co-operation between the MCIB and the accident investigation bodies of other states. These incidents were in general considered to be minor in nature and not warranting investigation by either the flag state or the MCIB, or were incidents where investigations were being conducted by the flag state. Some cases required the uploading of data by Ireland onto the European Maritime Casualty Investigation Platform (EMCIP).
