Maritime Questions › DP — Risk Assessment

The client representative wants to start a DP operation immediately, and asks the Master to skip the pre-task risk assessment review because "the standard one already covers it." The task today has a non-standard element (a heavier load than usual). What should the Master do?

A. Agree to proceed since the client is satisfied the standard assessment is sufficient
B. Delegate the decision to the DPO without involving the wider team
C. Proceed but verbally note the heavier load in the DP log afterward
D. Decline to skip the review — a non-standard element means the standard risk assessment may not adequately cover today's hazards; the review must be completed, even briefly, before work starts, regardless of client pressure

In the context of planning a DP operation, what is the fundamental difference between a HAZID and a HAZOP?
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

When preparing a task-specific risk assessment for a DP operation (e.g. a subsea lift), what DP-specific inputs must the risk assessment draw on, beyond generic task hazards?
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
