What is the validity period for a Declaration of Security at MARSEC level 1?

The validity period for a Declaration of Security (DoS) at MARSEC level 1 is indeed 90 days. A Declaration of Security outlines the security measures that are in place and the responsibilities of various parties while in a security context, particularly when dealing with vessels and facilities in the maritime environment.

MARSEC level 1 indicates a low level of security where there are minimal threats identified. The 90-day period allows for a reasonable timeframe during which the security measures can be assessed and maintained without the need for constant re-evaluation or re-documentation. This timeframe ensures that while security is managed effectively, it does not become a burden that hinders operational capabilities.

Implementing a 90-day validity helps streamline operations while ensuring that all parties are consistently aware of their roles and the security measures in place. It also aligns with the broader requirements set by the International Maritime Organization (IMO) under the International Ship and Port Facility Security (ISPS) Code, emphasizing the importance of regular assessments and updates to security practices.
