DP — Risk Assessment Practice Questions

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

A. Whether the work could affect any system relied on for the current WCF or active redundancy — the permit must be reviewed against the DP system status before issue, and the DPO/Master must be consulted and aware of any DP-critical system being isolated or worked on

B. DP operations must always be suspended before any permit-to-work is issued, regardless of what the work involves

C. The permit only needs Chief Engineer sign-off; the bridge does not need to be informed if the work is in the engine room

D. Hot work permits are entirely independent of DP status and only concern fire safety
