Arab Dark Fleet: Gulf Oil Producers Control 230 Tankers to Bypass Hormuz Risks
Gulf oil producers have taken control of a fleet of nearly 230 tankers that continue to move oil through the Strait of Hormuz despite Iranian opposition, according to Windward. This arrangement, described as the Arab Dark Fleet, represents the largest change in how Gulf national oil companies handle freight, logistics, and supply chains since the Tanker War of the 1980s.
The fleet is owned, managed, chartered, or controlled by Gulf national oil companies and their trading and shipping arms. It is intended to reduce dependence on spot-market tanker charters. Even with very high freight rates, fewer shipowners are willing to send vessels to load at terminals in Iraq, Saudi Arabia, Kuwait, Bahrain, Oman, or the UAE, so the dedicated fleet is used solely by Gulf states to keep their crude moving.
Dark Sailing and Ship-to-Ship Transfers
The fleet sails almost exclusively with its AIS transponders switched off in the Middle East Gulf, which the source attributes to legitimate safety and security reasons. Tankers load without transmitting their positions and then transit the Strait of Hormuz through Oman’s southern corridor with U.S. military support. Many have not signaled an AIS position for weeks.
The fleet combines tankers already held by national shipping companies with newly purchased vessels, chartered-in tonnage, and spot charters, many from private Greek shipowners. Global traders also shuttle oil loaded at west-of-Hormuz terminals and sold at a premium from transfer hubs or shipped directly to buyers, and their ships are counted in the fleet tally.
Ownership Mix and the South Korean Operator
The most significant addition is a South Korean shipowner half-owned by a large container line. That company began buying and chartering VLCCs in December 2025 and has built a fleet of more than 100 ships, about 70% of which now work in the Arab Dark Fleet. Its tankers account for nearly 30% of the fleet, making it the largest operator ahead of the national carriers.
The South Korean shipowner is also the most targeted by Iran, whose Persian Gulf Transit Authority has threatened legal action over use of the southern corridor.
Reversed Roles and Freight Costs
For decades shipping operated on the principle that cargo is king, but Gulf producers have concluded they must own or control tankers to move oil through the high-risk southern corridor in Omani waters, even at much higher freight costs. The source notes a mirror image of the 1984-88 Tanker War, when owners refused to load at Iran’s Kharg Island even at high rates and Iran ran a VLCC shuttle to the mouth of the Gulf for transshipment. Today the roles are reversed, with Arab producers running the shuttle under Iranian attack.
The fleet’s rise has added to freight inefficiencies and ties up roughly 15% to 20% of the global VLCC fleet at any one time. Gulf oil companies sell oil from ship-to-ship hubs at a discount to their official monthly selling price after shuttling it out of Hormuz.
