The Liberia Maritime Authority, through Marine Security Advisory 03/2025 Rev.2 (which supersedes Marine Security Advisory 03/2025/Rev.1), has issued updated guidance regarding elevated security risks in the Arabian Gulf, Strait of Hormuz, and Gulf of Oman, following recent regional military activity. Liberian-flagged vessels transiting these areas are required to operate at Security Level 2 and implement all applicable protective measures outlined in their Ship Security Plan (SSP).

Vessels must also register with UKMTO and MSCIO, report positions daily, and remain alert to GPS interference and AIS manipulation.

• All vessels are advised to report to UKMTO and register with the Maritime Security Centre – Horn of Africa (MSC-HOA), in line with industry Best Management Practices (BMP) for maritime security in high-risk areas.
• Daily position reports to UKMTO are recommended at 08:00 UTC.
• Voluntary reports to IFC-IOR are encouraged to support regional maritime security cooperation.

Any security incidents or suspicious activity must be reported immediately to the Liberia Maritime Security Department. (security@liscr.com)
