Between 2019 and 2022, 84.0% (12,363) of marine incidents included a Technical occurrence type. There was a steady increase in technical occurrences from 2019 to 2022, with 2022 resulting in a total of 3702 technical occurrences with 4.5% (126) of technical occurrence categorised as very serious or serious incidents (Figure 26, Table A9).
In 2022, vessel system failures comprised the majority of technical occurrence types having increased steadily from 263 in 2019 to 653 in 2022 (Figure 26). This increase is attributed to a significant increase in the reporting of ballast system failures from 57 in 2019, to 343 in 2022 (Figure 27).
In 2022, 17.3 % (639) of technical occurrences involved power, propulsion and/ steering system failures. Main engine and gearing failures were the most frequently reported technical failures and were amongst the top 3 technical occurrences for all vessel types except passenger vessels (Figure 27, Table A-10).
Figure 27 shows the top 10 failures in equipment associated with propulsion, power/steering; engineering systems, cargo and stores, and vessel access in 2022. These included:
