The shadow tanker fleet transports growing volumes of sanctioned oil around the world, generates billions of dollars in revenue for russia and Iran, threatens environmental safety in the oceans, serves as a spy platform, and is used for sabotage activities in the interests of the aggressor.
The sanctioned countries are looking for new markets for oil, building up their tanker fleet to circumvent restrictions, and shipping crude oil mainly to China and India.
The shadow tanker fleet with a total deadweight of more than 100 million tons (approximately 17% of the world`s oil tanker fleet) consists of more than a thousand mostly outdated, poorly maintained vessels without proper insurance, with ‘confusing’ ownership and management structures located in ‘friendly’ jurisdictions, under ‘convenient’ flags. Such vessels resort to deceptive tactics at sea to conceal the origin of their cargo, threaten ‘environmental chaos’ and billions of dollars in losses to coastal countries by passing through busy, narrow international transportation routes without pilotage. Since the beginning of russia`s full-scale invasion of Ukraine, shadow tankers have already been involved in more than 50 incidents from the Danish Straits to Malaysia.

On April 04, 2024, the USA imposed sanctions on the tanker ІМО 9281683, involved in cooperation with the sanctioned Iranian company Sepehr Energy Jahan Nama Pars Company in the delivery of Iranian goods. Sepehr Energy Jahan Nama Pars Company controls a network of front companies in Iran and other jurisdictions through which Iranian goods are sold in favor of the Ministry of Defense and Logistics of the Armed Forces of Iran (MODAFL) and the Iranian Armed Forces General Staff (AFGS).
Since December 16, 2024, the EU has imposed sanctions on the tanker for the transportation of crude oil or petroleum products originating in or exported from russia, using irregular high-risk shipping practices as set out in the International Maritime Organization General Assembly Resolution A.1192(33).

The tanker is involved in the supply of Iranian oil to China.
The Iranian Armed Forces General Staff (AFGS) and its main commercial subsidiary, Sepehr Energy Jahan Nama Pars Company (Sepehr Energy), continue to create front companies and rely on buyers and intermediaries to facilitate their authorized oil trade. AFGS and Sepehr Energy continue to rely on access to a fleet of aging shadow fleet oil tankers to supply oil to foreign buyers. As of early 2025, Sepehr Energy official Toomaj was using vessel IMO 9275660 to facilitate the supply of Iranian oil to China.
Many tankers involved in transporting Iranian oil to countries such as China are also involved in Venezuelan trade, including tanker IMO 9235244. On June 11, 2022, Venezuelan leader Nicolás Maduro and former Iranian President Ebrahim Raisi signed a 20-year cooperation agreement to expand ties in the oil and petrochemical industries, as well as in the military and economic spheres. Since then, bilateral ties have begun to develop. Most cargo is transported by ships belonging to the sanctioned National Iranian Tanker Company (NITC) in both directions. A significant number of ships flying under foreign (non-Iranian) flags are also involved in this trade.
On May 13, 2025, the US imposed sanctions on the tanker.

The vessel is involved in the provision of fuel oil bunkering services for ships in Iranian waters under contracts worth millions of dollars signed during 2024 with the sanctioned National Iranian Oil Company, which provides material support to the Islamic Revolutionary Guard Forces.
The vessel is affiliated with a sanctioned person, Brar Jugwinder Singh, through a sanctioned company, Glory International FZ-LLC, of which he is a director and owner. Brar, through its companies, owns, operates or manages a fleet of nearly 30 oil and petroleum product tankers, most of which are Handysize tankers that stick to coastal waters and carry a fraction of the cargo of larger tankers. Brar uses the smaller tankers for STS transfers to load Iranian oil from other shadow fleet vessels or to load oil or fuel that is smuggled from smaller commercial and fishing vessels. Thus, Brar coordinated with the illegal shipping associates of Houthi financial official Said al-Jamal on sanctions evasion tactics, including the use of smaller vessels instead of large oil tankers to conceal the smuggling of Iranian oil in the Persian Gulf and Khor al-Zubair (Iraq) and their environs.
On April 10, 2025, USA imposed sanctions on the vessel as a property in which Glory International FZ-LLC has an interest.
