Who holds ultimate responsibility for ensuring a DP operation's risk assessment is adequate and current before work begins, even if a Risk Assessor or Toolbox Talk leader has prepared it?

A. Whoever physically signs the risk assessment form bears sole responsibility, regardless of rank

B. Responsibility is shared equally and informally among the entire crew with no single accountable person

C. The Master retains ultimate responsibility for the safety of the vessel and operation, even where preparation of the risk assessment has been delegated — sign-off by a junior officer or specialist does not transfer that overall responsibility away from the Master

D. The classification society is responsible since the DP system is class-certified

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

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

C. 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

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

A. 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

B. Only the crew's certification and rest hours

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
