During which scenarios might the gangway be secured or closed?

The correct scenario involves securing or closing the gangway during a security drill, at night, or when there is a recognized threat. In these situations, the safety and security of the vessel and its crew are paramount. Securing the gangway helps to prevent unauthorized access and reinforces safety protocols during drills, ensuring that crew members are familiar with emergency procedures.

At night, the visibility is reduced, and securing the gangway mitigates risks associated with limited sightlines and potential unauthorized boarding. When there is an identified threat, whether to the ship or its personnel, closing the gangway acts as a protective measure against potential intruders or hazards, ensuring the vessel remains secure.

While it might seem reasonable to consider situations like severe weather or VIP arrivals for closing the gangway, these do not directly align with the core security protocols that dictate such actions primarily revolve around safety drills and perceived threats.
