A RoPax Master receives a report of a vehicle fire developing on the cargo deck while passengers remain on board. Your examiner asks: "What command-level decisions take priority?"

A. Initiate the fire/general alarm and the vessel's emergency response (boundary cooling, fixed suppression activation as appropriate, isolating ventilation to that space), simultaneously assess whether the situation requires passenger muster/precautionary movement away from the affected area, maintain command oversight of both the firefighting response and passenger management rather than treating them as sequential, and consider whether the severity requires informing nearby vessels/coastguard early rather than waiting to see if the fire is brought under control — passenger safety management and firefighting must run in parallel, not one after the other.

B. Passenger management should always wait until the fire is fully extinguished before any communication or precautionary action is taken with passengers.

C. A vehicle deck fire on a RoPax vessel requires no different command approach from an equivalent fire on a vessel with no passengers aboard.

D. External notification (coastguard/nearby vessels) should only occur once the Master has personally confirmed the fire cannot be controlled, with no earlier precautionary contact.

A. The Master retains ultimate responsibility for the vessel's watertight integrity and seaworthiness before departure, even though the practical checks are delegated to officers/crew — the Master must be satisfied (through a reliable reporting/confirmation chain, not just assumption) that all watertight doors required to be closed for sea are in fact closed and confirmed before giving the order to proceed; several real RoRo capsizing/flooding casualties have specifically involved doors left open or unconfirmed at the point of departure, which is why this is treated as a non-delegable command responsibility even though the physical check itself is delegated.

B. Watertight door status before departure is entirely the Chief Officer's responsibility, with no residual Master accountability once delegated.

C. The Master's responsibility ends once a written departure checklist has been signed, regardless of whether the underlying checks were actually carried out.

D. Watertight door checks are a class society surveyor function at each port, not a routine Master/ship's-staff responsibility before every departure.

A. Confirm the vessel's current loaded/operating condition remains within the parameters assumed by the Stockholm Agreement survivability assessment (e.g. any structural modifications, draught/trim limits, freeboard, or watertight door/closure status that the assessment relied on); ensure crew understand and maintain the watertight closures and any cross-flooding arrangements the compliance relies on; and treat Stockholm Agreement compliance as an ongoing operational state to be maintained, not a one-off newbuild certification that, once issued, requires no further attention.

B. Once a vessel is certified Stockholm Agreement compliant at build, no further verification or operational maintenance of that compliance is required for the vessel's service life.

C. Stockholm Agreement compliance is verified solely by the flag state on an annual basis, with no Master-level operational responsibility.

D. The Stockholm Agreement applies only to the vessel's structural design and has no operational/Master-level compliance dimension at all.
