You notice the vessel's International Ship Security Certificate (ISSC) is due to expire in three weeks, during a period when the vessel will be on passage between two countries with limited port calls. What are your responsibilities regarding this certificate?

A. The ISSC can be renewed by the Master alone, without involvement of the flag state or a recognised organisation

B. Only the CSO needs to know, and no onboard action is required regardless of timing

C. Bring this to the Master's and Company's attention promptly so that a verification/renewal survey can be arranged before expiry — an ISSC is normally valid for up to five years subject to intermediate verification, and operating with an expired ISSC can result in the ship being detained by port state control or refused entry/services at the next port, similar to other statutory certificates

D. The ISSC never expires once issued, so no action is needed

A. Security levels only apply to passenger vessels

B. No action needed until the vessel actually arrives in port

C. Only the Master needs to be informed; no operational changes are required

D. Implement the additional security measures specified in the Ship Security Plan for Security Level 2 (e.g. increased monitoring of restricted areas, additional checks on visitors/stores, more frequent security patrols) before arrival, and acknowledge/report the change as required

A. To give crew somewhere private to relax

B. To control access to areas where security-sensitive information, equipment, or cargo is held (e.g. bridge, engine room, security equipment stores), preventing unauthorised access that could compromise the security of the ship, crew, passengers or cargo

C. They are purely for fire safety, unrelated to security

D. Restricted areas are only required on vessels carrying dangerous goods
