Your vessel is preparing to enter port. What is the SOLAS requirement for opening of the vessel's cargo hold watertight doors in this situation?

Correct Answer: Option C — the doors shall remain secured while the vessel is navigating

SOLAS Chapter II-1, Regulation 22 dictates that watertight doors must remain closed and secured while the vessel is navigating. Opening these doors for cargo operations is only permitted once the vessel has safely arrived and is secured in port, ensuring the vessel's subdivision integrity is maintained at sea.
