Station Keeping Events STATS
2024 saw a record number of event forms being submitted in to IMCA, with 217 forms from 56 companies submitted. This month each of those companies received their certificate of participation, to show our appreciation for them taking the time to complete and report their events, whether big (incident) or small (observation).

The secondary failures recorded (the trigger behind the event) continues to be same top three as previously years, namely electrical, mechanical and human and though still higher than precovid, the percentage of DP incidents appears to be on a downward trend.
