EXECUTIVE SUMMARY

• Russian-flagged LNG carrier ARCTIC METAGAZ suffered a series of explosions and sank in the Maltese EEZ.
• The attack was attributed to Ukrainian forces by the Russian Ministry of Transport.
• Within 48 hours, Russia targeted a bulk carrier sailing from Chornomorsk.
• A reciprocal Ukrainian action is likely.
• Risk to vessels sailing to Russian Black Sea ports may extend beyond territorial waters into EEZs, including Turkish approaches.
• In late 2025, early 2026, Ukraine targeted mostly, but not solely, sanctioned tankers.
• Russian targeting was largely opportunistic and vessel type indiscriminate.  

SITUATION

On 2 March 2026, the Russian-flagged LNG carrier ARCTIC METAGAZ, en route from Murmansk to China, suffered a series of explosions followed by a significant onboard fire in the central Mediterranean, in Malta’s EEZ. All 30 crewmembers were reportedly rescued. Subsequently, Russia’s Ministry of Transport stated that the vessel was attacked by an unmanned surface vehicle (USV), allegedly launched from the Libyan waters, and attributed responsibility to Ukrainian forces. If confirmed, this would mark a first known use of Ukrainian USVs outside of the Black Sea. At the time of writing, there has been no official confirmation from Ukraine. The vessel has previously been reported as subject to U.S. and U.K. and Ukrainian sanctions.

On 3 March 2026, a Liberia-flagged bulk carrier was damaged by a Russian missile whilst exiting the port of Chornomorsk, Ukraine. Reportedly, the missile struck the vessel’s port quarter. The vessel suffered structural damage and water ingress. One crew member was seriously injured. The vessel managed to continue to sail, and upon arrival in Romanian waters, the vessel altered its course toward the port of Constanta to conduct a more detailed damage survey and to deliver the injured crew member to the Romanian Coast Guard for medical assistance. 

THREAT UPDATE

Over the past 30 days, Ambrey observed a marked decline in direct attacks against merchant vessels in the Black Sea. While strikes against port and energy infrastructure continued, both sides appeared to exercise a degree of tacit operational restraint regarding merchant shipping itself. The recent incidents materially alter that dynamic. Russia reportedly retaliated within 48 hours of the alleged Ukrainian attack in the Mediterranean, indicating a rapid response posture and raising the prospect of renewed targeting of merchant vessels.

The attack against a vessel outbound from Chornomorsk increases the likelihood of reciprocal Ukrainian action, which could effectively collapse the informal restraint observed in recent weeks. Ambrey assesses there is a realistic possibility of retaliatory action affecting merchant vessels transiting to and from Russia in the northern Black Sea. Vessels inbound in ballast are assessed to face a higher threat of direct attack than laden vessels, consistent with previously observed targeting patterns.

Should escalation materialise, several operational impacts are likely. Vessels en route to and from Ukrainian ports would face a heightened threat of direct attacks, while sanctioned tankers trading to Russian hydrocarbon export facilities are likely to become priority targets. The threat to non-sanctioned tankers will also increase. The threat envelope may extend beyond territorial waters into exclusive economic zones, including approaches through Turkish waters.

Ukrainian forces have previously targeted both sanctioned and non-sanctioned vessels linked to Russian trade. Such targeting has included overt kinetic attacks as well as covert sabotage operations, including the use of limpet mines, which can cause damage that may only become apparent days or weeks after a vessel call.

In summary, all vessels operating in the northern Black Sea face a heightened threat of direct attack should escalation continue.

Further developments will determine whether this incident represents a temporary escalation or signals the resumption of sustained targeting of merchant shipping in the Black Sea.

RECOMMENDATIONS

• Affiliation checks against the Ukrainian and Russian target profile:

• Ambrey recommends that a thorough affiliation check as part of a voyage risk assessment be performed for Black Sea voyages. Ambrey continues to adjust these assessments as per the developing intent and threat.
• Vessels strongly affiliated with the target profile are advised to avoid transiting in the Russian, Ukrainian and Turkish waters.

• Ambrey also recommends that vessels conduct dynamic voyage threat assessments in the Black Sea.
