Beyond a scheduled periodic review, what specific events should automatically trigger a re-review of a DP operation's risk assessment?

A. A change in personnel, equipment status (e.g. a thruster or reference system fault), weather/sea state, task scope, or any near-miss/incident during the operation — any of these can invalidate the original assumptions

B. Risk assessments only need reviewing annually regardless of operational changes

C. A review is only triggered by a formal incident report being filed

D. Only a change of Master triggers a review

A. A HAZID (Hazard Identification) is a broad, early-stage exercise to identify what could go wrong across the whole operation; a HAZOP (Hazard and Operability study) is a more structured, systematic review of a specific system or procedure using guide words to probe deviations from intended operation

B. A HAZID is only used for diving operations; a HAZOP is only used for drilling operations

C. A HAZOP is conducted by the DPO alone; a HAZID requires the whole bridge team

D. They are interchangeable terms for the same process required by different classification societies

A. Only the crew's certification and rest hours

B. The vessel's WCF, current ASOG limits, footprint/consequence analysis for the specific location, position reference availability, and proximity to fixed/floating structures or other vessels

C. Only the weather forecast for the next 24 hours

D. DP-specific factors are not part of a task risk assessment — they are covered separately in the FMEA
