Marine Security Bulletin: 38/2026 - Multiple Vessel Attacks in the Black Sea

Dear Shipowners, Operators and Masters

Subject: Multiple Vessel Attacks in the Black Sea

A Liberian flagged bulk carrier was struck on 29 September and again on 2 October by multiple unmanned aerial vehicles while moored at the port of Chornomorsk, Ukraine in position 46° 19.1’N 030° 39.5’E. The attack caused damage to the vessel’s starboard aft side of the navigation bridge structure and to the port side accommodation structure. A small fire broke out following the impact but was quickly extinguished by the crew members. Further damage assessments are ongoing. Master reports that one crewmember is deceased and three others are injured.

Liberian flagged vessels are to operate at security level 2 while transiting the affected area and at security level 3 while in Ukrainian ports in accordance with MSA 10/2022 and implement all protective measures in their Ship Security Plan. Vessels at other ports in the affected area are required to act upon the security level set by the Designated Authority at those ports.

Operators and Masters should ensure that any planned operations or voyages do not take the vessel into any area, or engage in any activity, that would expose her to the risk of ongoing military operations. Vessels operating in these areas may encounter GPS interference, AIS spoofing, and/or other communications jamming. Vessels should ensure they are broadcasting on AIS (except when the Master believes that continuing to operate AIS might compromise the safety or security of the ship or when a security incident is imminent) and clearly state their intentions across VHF, consistent with provisions of the International Convention for Safety of Life at Sea (SOLAS), and monitor VHF Channel 16. Any vessels challenged by military vessels should comply fully with instructions.

Recommendations

Ships Masters should obtain the relevant NAVAREA III warnings and contact the local port authorities and ships agents for additional information. Ships navigating in these areas should also monitor NAVTEX messages, maintain a proper lookout for suspicious drifting objects and report immediately to ships and coast radio stations in the area with position and direction and speed of wind and current.

This is a dynamic situation, and changes may occur at any time. Owners, Operators, Company Security Officers and Masters are suggested monitoring the developments and liaising closely with local port agents and P&I correspondents for the latest information on facility conditions, dangerous sea areas and temporary port closures and navigational restrictions. Vessel operators and Masters are recommended to reference IMO Circular Letter No. 5252 prior to finalizing voyage planning in the region and proceed with appropriate caution.

Operators and Masters should complete a Risk Assessment prior to entering the Black Sea area. In the event of any incident or suspicious activity, Liberian flagged vessels should activate the Ship Security Alert System (SSAS) immediately and notify the Liberian Security Department.
