U.S.-Led Ship-to-Ship Oil Transfers Near the Strait of Hormuz

Operation Overview: Clandestine Ship-to-Ship Transfers
On 9 June 2024 a U.S. Army AH-64D Apache helicopter was shot down by Iran after a U.S. retaliatory bombing campaign. Four sources, including a former U.S. official, say the Apache was part of a covert ship-to-ship oil-transfer operation intended to keep Gulf crude flowing. The scheme employed aerial and water drones and helicopters to guide convoys to tankers at two sites: off Fujairah in the United Arab Emirates and near Oman’s port of Sohar. Reuters-reviewed satellite imagery showed six pairs of tankers clustered off Sohar on the day the Apache was downed and, by 11 June, 17 pairs operating simultaneously at the two locations.
Background & Context: Iranian Blockade and Global Energy Impact
Iran’s response to the U.S.–Israeli strikes effectively closed the Strait of Hormuz, a chokepoint through which roughly one-fifth of world oil passes. The closure produced the largest recorded global energy-supply disruption, contributing to worldwide inflation. To sustain Gulf exports, the United States and its allies turned to alternative routes, including the ship-to-ship transfers.
Key Figures & Groups: Participants and Oversight
The United States supplied aerial surveillance, compliance screening, and monitoring through the U.S. Navy’s Naval Cooperation and Guidance for Shipping office in Bahrain, but no direct naval escort. Receiving vessels were operated by international tanker firms, notably Greece-based Dynacom Tankers Management and the United Arab Emirates’ state-owned ADNOC, identified as the most active participants. The Kuwait Oil Tanker Company also contributed ships. Analysts cited include Noam Raydan (Washington Institute) and Michael Froman (Council on Foreign Relations). Dynacom founder George Procopiou publicly defended the operation’s principle of freedom of navigation.
Data & Statistics: Scope of the Transfers
Shipping data and satellite imagery indicate that at least 92 ships participated from early May through 11 June, forming 17 simultaneous pairs at peak. Reuters estimated roughly 90 million barrels of crude and petroleum products moved through the offshore network during this period, compared with a pre-war average of about 20 million barrels per day transiting the strait. On 6 June, approximately 2.3 million barrels were transferred from a Kuwait Oil Tanker Company vessel off Sohar; the receiving tanker, Sea Ruby, later headed toward China.
Official Statements & Responses
A U.S. defense official told Reuters that no CENTCOM forces were involved in the offshore transfers. The White House directed questions to CENTCOM for clarification. President Donald Trump announced that the Strait of Hormuz would reopen on a Friday under a “framework peace deal” with Iran, though details were not disclosed. The Iranian government declined to comment on the transfer operation.
Criticism & Opposition
Noam Raydan warned that Iran could employ drones or gunboats to block ships attempting the transfers. A maritime-security source highlighted a “paucity of reliable data” and noted that disabled transponders and dimmed lights increase collision risk. Michael Froman observed that the United States appears to be adopting sanction-evasion tactics pioneered by Iran and other “dark fleets.”
Verbatim Quotes
- “You just don't know when Iran might decide to start using drones or even gunboats in order to prevent even those ships from transiting the strait.” — Noam Raydan, senior fellow, Washington Institute
- “Freedom of navigation is essential and nobody can impose tolls or any other burden. We are here to serve, and Greece has the tradition of breaking blockades since antiquity. I don't want to go into more details, but I believe the hints are enough to understand what I mean.” — George Procopiou, founder, Dynacom Tankers Management
- “There is a paucity of reliable data,” the maritime security source said. “Companies are not reporting through the usual reporting centers.” — Unnamed maritime security source
- “This is a temporary solution amid exceptional times.” — Noam Raydan, senior fellow, Washington Institute
Conflicting Reports & Gaps
Reuters could not independently verify the Apache’s direct role in the transfers, while four sources claim involvement. The compliance-review process and the full list of participating vessels remain undisclosed, creating uncertainty about the operation’s transparency.
What’s Next
President Trump’s announced framework aims to reopen the Strait of Hormuz, which could reduce reliance on offshore transfers. U.S. officials intend to continue monitoring vessel movements through the Bahrain office, and shipping firms are expected to seek further compliance approvals if the transfers persist.
