RMI issued a Ship Security Advisory 10/2025 and this Ship Security Advisory (SSA) supersedes SSA 08-23.

Russia and Ukraine continue to execute military operations, suggesting military and drone attacks on Ukrainian and Russian infrastructure will continue, particularly against energy-related targets as well as maritime vessels and ports. Maritime entities remain at risk of direct targeting, collateral damage, and Global Navigation Satellite System (GNSS) interference.

Ukrainian forces have conducted repeated strikes on Russian energy infrastructure, including a second attack on the Tuapse oil terminal and a combined Unmanned Aerial Vehicle (UAV) / Unmanned Surface Vessel (USV) operation on 3 November 2025 against a Russian-occupied offshore drilling rig in the Black Sea.

Ukraine’s temporary maritime corridor remains in use but carries significant risk, including potential harassment, collateral damage from strikes, and hybrid threats such as GNSS interference. The European Union’s Black Sea Maritime Security Hub, launched in May 2025, enhances regional monitoring of critical infrastructure like submarine cables and offshore installations to counter Russian hybrid activities, including sabotage.
