Your examiner asks: "As OOW, if you noticed a watertight door on the vehicle deck was not properly closed before departure, what would you do?"

A. Report it immediately to the responsible officer/bridge and ensure the door is properly closed and confirmed (via indicator and physical check if accessible) before the vessel proceeds to sea — an improperly secured watertight door undermines the vessel's damage stability assumptions and is not a defect to leave for "later," given several real RoRo flooding casualties have involved doors not properly secured before sailing.

B. It is acceptable to depart and close the door once the vessel is clear of port, since watertight integrity is only relevant once in open water.

C. Only the Master needs to be informed after arrival at the next port; the issue does not need to be addressed before departure.

D. Watertight door status has no bearing on departure readiness and is checked only during scheduled drills, not before every sailing.

A. A RoRo vehicle deck is typically a large, open space with high fuel-load density (vehicles carrying their own fuel, sometimes with engines running during loading/unloading) and limited internal subdivision compared to cellular cargo holds — a fire can spread rapidly across the open deck with few barriers, which is why fixed fire-detection and fire-suppression systems on vehicle decks, and strict rules on running engines and smoking, are taken especially seriously.

B. RoRo vessels have no greater fire risk than any other cargo ship type; the open deck arrangement has no bearing on fire spread.

C. Fire risk on a RoRo deck applies only to vehicles carrying dangerous goods; ordinary private vehicles present no fire risk at all.

D. Vehicle deck fire risk is addressed solely by the IMDG Code, with no SOLAS Chapter II-2 RoRo-specific provision.

A. Crew should have RoRo-deck-specific familiarisation covering vehicle movement hazards, blind spots around larger commercial vehicles, designated pedestrian routes away from active vehicle lanes, awareness of exhaust fume accumulation risk from running engines, and high-visibility PPE — this familiarisation should happen before a new crew member is required to work the deck unsupervised, not learned informally on the job.

B. No specific training is required beyond the general safety induction given to all new crew on joining, regardless of department or task.

C. Only the stevedoring company's own staff need training; ship's crew working in the same space have no separate training requirement.

D. Vehicle deck familiarisation is required only for engine room crew, not deck department crew who actually work the cargo deck.
