DP — Incident Reporting Practice Questions

A. Any unintended, uncontrolled vessel movement (excursion) or loss of position, thruster runaway (drive-off), loss of redundancy that constituted a genuine risk to the operation, or any DP-related event that could have resulted in a collision, grounding, or loss of life — regardless of whether actual contact or damage occurred

B. Only incidents where the vessel moved more than 50 metres from its setpoint

C. Reporting is voluntary — the vessel operator decides whether to submit a report

D. Only incidents where a structure was struck or a person was injured

A. Any movement of a DP vessel, including planned transits

B. A report submitted by the client after a DP vessel leaves their location

C. A standardised category of DP incident in which the vessel experienced an unintended and uncontrolled excursion from its position setpoint, or a loss of position — the defining characteristic is that the excursion was uncontrolled (not intentional or commanded by the DPO)

D. A category of vessel that exclusively carries out DP operations

A. Near-misses are reported to the flag state, not IMCA

B. IMCA only collects incident data — near-misses are outside the scheme

C. Only incidents with actual damage are reportable; near-misses are optional

D. A DP incident resulted in actual position loss or contact; a DP near-miss had the potential for serious consequences but did not result in actual position loss or contact — both are reportable under IMCA's scheme and both carry equal reporting value for safety learning
