Italian operation against Russian shadow fleet: Tanker "Toa Payoh" inspected in the Mediterranean

Background: The IRINI Mission

According to the information available so far, the "Toa Payoh" is suspected of being part of the Russian shadow fleet. The term shadow fleet refers to tankers that, with concealed ownership structures, changing flags, and often questionable insurance, attempt to circumvent Western sanctions and enable Russian oil and product exports. The exact role of the individual vessel has not yet been conclusively confirmed.

The inspection of such vessels follows a defined procedure under maritime law. First, the ship is stopped; then documents are examined, the crew and cargo are inspected, and the flag state is determined. Italy reports that the ship had been operating under the flag of a state that, according to ministry sources, is connected to practices of concealment. Further details on the flag were not initially provided in the statement.

Suspected connections to the shadow fleet

The port registry of Istanbul shows that the "Toa Payoh" was last registered in Turkish waters. Istanbul is known as a transshipment point for tanker transports from the Black Sea. Whether the registration was still current at the time of the inspection remains unclear. The Italian Ministry of Defense did not initially comment on this.

Reactions from Russia to the specific incident were not initially known. In the past, Moscow had repeatedly rejected similar inspections as unlawful. The EU mission IRINI had been expanded, among other things, after the Russian attack on Ukraine, in order to make it more difficult to circumvent the oil price cap and other sanctions via maritime routes.

Italian authorities announced that further information on the whereabouts and cargo of the ship would be published after the inspection was completed. Whether the crew will be detained, the cargo seized, or the ship escorted to an Italian port depends on the outcome of the document check. A possible involvement of the coast guard and the judicial authorities was also left open.

Reactions and political significance

International observers assess the incident as part of a broader European effort to dry up the shadow fleet. In recent months, several EU states had reported similar inspections, for example off the coasts of Greece, France, and Denmark. The EU Commission had also announced that it would regularly update the list of sanctioned vessels.

The political significance of the operation goes beyond the individual case. The shadow fleet is considered one of the main routes through which Russia generates revenue from oil and fuel exports despite Western sanctions. According to analysts, each inspection increases the logistical effort and thus the costs of circumventing sanctions.

At the same time, maritime law experts point out that every stop of a vessel sailing under a false flag must be precisely documented in legal terms. Only if there is an actual violation of sanctions or maritime law may a ship be permanently detained. According to the Ministry of Defense, the final assessment of the "Toa Payoh" case is still pending.

The EU mission IRINI has been running since 2020 and has been extended several times. Its main mandate covers the implementation of the arms embargo against Libya, but in recent years it has increasingly also been used to monitor sanctions evasion. Italy's participation is traditionally strong, as the country lies directly adjacent to the operational areas with Sicily and Pantelleria.
