Who jointly issues a Declaration of Security (DoS)?

The Declaration of Security (DoS) is an important document that outlines the security measures agreed upon between a ship and a port facility when they are engaged in a specific operation, particularly when the ship and the facility present differing security levels. The correct answer indicates that this document is jointly issued by the Port Facility Security Officer (PFSO) and the Ship Security Officer (SSO).

The PFSO is responsible for ensuring the security of the port facility and its operations, while the SSO manages the security requirements on the ship. When security threats or concerns arise, both officers collaborate to assess risks and establish preventative measures. This joint responsibility highlights the necessity of coordination between the ship and the port to maintain security in the maritime environment.

The collaboration between these two roles is crucial during specific security situations such as when a ship is entering or leaving the port or when the security level of either the ship or the port facility changes. By working together, the PFSO and the SSO can ensure that all necessary security protocols are in place, fostering a safer operational environment for all parties involved.
