Between 2019-2022, 29.3% (957) of DCV marine incidents included a technical equipment failure with power propulsion and steering comprising 50.0% (519) of technical occurrence types (Figure 14).
The majority of power propulsion and steering technical occurrence types (green in Figure 14) in 2022 were main engine and/or gearing failures (50.3%).
In 2022, 81.6% of vessel system technical occurrence types (yellow) were mooring and anchoring equipment failures.
The majority of engineering systems occurrence types (light blue) included fuel (28.3%), electrical faults (19.6%) and hydraulic system failures (15.2%). Electrical failures pose a significant concern noting the fire risks associated with faulty electrical systems (Figure 15, Table A6).
