Sanctioned Turkish operator Beks Ship Managemen resumes shipping Russian oil under new flags.
The “shadow fleet” of oil tankers and bulk carriers that power Russia’s sanctions evasion often shuffle their listed ownership or management—a revolving door of paper-only changes that do little to alter the underlying risks, or the core network of operators.
Take the example of Beks Gemi Isletmeciligi Ve Ticaret A.S. (Beks Gemi), a Turkish vessel-management company sanctioned by the U.K. last year for its involvement in shipping Russian oil. Afterward, Beks Gemi transferred some of its vessels’ operations to a different Turkish company that remains off sanctions lists.
Both companies, a Kharon investigation found, are owned and managed by close affiliates and possible family members. And the network’s vessels continued to export Russian oil.
Justification
Vessel information IMO 9275763
The tanker during the period of the G7 and EU oil embargo and the price cap policy on russian crude oil/petroleum products is involved in the export of russian crude oil/petroleum products.
The tanker is affiliated with the Turkish company Beks Tanker Isletmeciligi AS, which managed the vessel from January 2023 to March 2024. Beks Tanker Isletmeciligi AS is one of the top three ranking Turkish operators, which in 2023 provided transportation of hundreds of millions of barrels of russian crude oil and petroleum products. The fleet of the Turkish top three – Beks Tanker Isletmeciligi AS and the sanctioned Beks Gemi Isletmeciligi ve Tic and Active Denizcilik ve Gemi – transported a total of 49 million barrels of russian crude oil/petroleum products in 2023. In March 2024, the management of the tanker was transferred to the Turkish company Cape Gemi Isletmeciligi AS. Cape Gemi Isletmeciligi AS has the same legal address as two other Turkish ship managers, Sand Gemi Isletmeciligi AS and Tokyo Gemi Isletmeciligi AS. Eight tankers of these companies were operated by Beks Tanker Isletmeciligi AS in 2023 and early 2024, and one tanker was operated by the sanctioned Beks Gemi Isletmeciligi ve Tic.
On May 20, 2025, the EU imposed sanctions, which will enter into force on May 21, 2025, on the tanker for the transportation of crude oil/petroleum products originating in or exported from russia, using irregular high-risk shipping practices as specified in the International Maritime Organization General Assembly Resolution A.1192(33).
On June 03, 2025, the sanctions imposed by Switzerland on the vessel came into force.

News to know: The EU, Canada and the U.K. expanded their sanctions on Russia’s shadow fleet last month, part of a larger escalation to constrict Russia’s oil and gas industry and to curb the transfer of drones, missiles, and related technology to Russia.
According to Bloomberg, the U.S. vetoed a G-7 proposal this month that would have established a task force to combat Russia’s shadow fleet.
Inside the network: Several Turkish nationals are at the center of the Beks Gemi network. Beks Gemi’s founders and owners include Ali Bekmezci and Cemil Ersoz. After the U.K. sanctioned Beks Gemi, in February 2024, it transferred the management of 16 vessels to Spark Gemi Isletmeciligi AS (Spark Gemi), which is owned and directed by two Turkish nationals who share the same surnames: Ceyda Bekmezci and Zehra Ebru Ersoz, demonstrating the firms’ potential interlinked leadership.
Fifteen of the former Beks Gemi ships are owned by Panamanian companies that Beks Gemi founders Ali Bekmezci and Cemil Ersoz co-manage with the majority owner of Spark Gemi, Ceyda Bekmezci.

Little control appears to have changed.
Connecting the dots: The CORTEX and OASIS are two oil tankers that Ali Bekmezci and the Beks Gemi network once operated and ultimately owned. According to trade data, both ships continued to transport Russian oil after Beks Gemi’s designation, with the OASIS making port calls in Russia as recently as December.
The E.U. that month designated both vessels themselves. Afterward, Beks Gemi transferred operations of the CORTEX and OASIS to two separate Panamanian companies that share the same Turkish directors:

The name of one of the Panamanian companies, Tower Maritime and Trading Inc., is nearly identical to that of a company that used to be in both ships’ ownership chains: Tower and Maritime Trading Ltd. Registered in Hong Kong, it’s wholly owned by Ali Bekmezci.
Rewind: A Kharon investigation published last month detailed an oil-shipping shadow-fleet network operated by 12 interconnected companies, only one of which was sanctioned. Three weeks after the U.S. designated one of that company’s ships, the GOODWIN, it changed its name and falsified its flag to Guyana’s, Kharon found.
Takeaways: These shadow-fleet networks are constantly evolving, whether by shifting their listed owners or managers, their vessels’ names, or their jurisdictions, often to ones where beneficial-ownership information can be more opaque.
As Western governments continue to target such networks, vigilant monitoring will be vital for businesses to avoid possible sanctions violations.
