II.7. Declaration of Security (DOS)
The Declaration of Security (DOS) provides a means for ensuring that critical security concerns are properly addressed and security will remain in place throughout a vessel’s stay at the facility. Security is properly addressed by delineating responsibilities for security arrangements and procedures between the vessel and the facility. At MARSEC Level 1, no DOS is required for this facility. At MARSEC Level 2 and Level 3, the FSO will sign and implement a DOS with interfacing manned vessels.
The DOS will be completed by:
• the Vessel Master or the VSO, and/or
• the FSO or designee.
An Example DOS is provided in Annex 3. Each DOS will address the security requirements that can be shared between the facility and the vessel. It shall state the specific responsibilities of each. Additionally, the FSO will be familiar with NVIC 10-02, Security Guidelines for Vessels, to ensure that critical security responsibilities are properly delineated and that those responsibilities remain in place while a vessel is moored at the facility.
Both the facility and the vessel will keep a copy of the DOS and a copy will be made available to the Captain of the Port upon request.
For vessels that frequently visit the facility, at MARSEC levels 1 and 2, a DOS is not required for every interface if a written agreement has been entered into that states the responsibilities for each during a facility/vessel interface. At MARSEC Level 1, a continuing DOS can not exceed ninety days. While in MARSEC Level 2, a continuing DOS agreement can remain valid for not more than thirty days. When the MARSEC level increased beyond that contained in the DOS, the continuing DOS is void and a new DOS must be executed. All such agreements, including currently valid continuing DOS, once established, will be attached to this plan.
