ALBAWABA - In an exclusive Reuters report, the U.S. has overseen and supported dozens of secretive ship-to-ship oil transfers, avoiding Iranian blockades and attacks.The method, used by Iran to avoid sanctions and blockades for years, involves transferring cargo between ships to mask its origin. In its simplest form, a ship would hand off its cargo to another ship on the way to the same destination with the transfers taking up to 24 hours to be done in the middle of the sea.The locations where the oil transfers took place in the Gulf of Oman were identified by 11 people familiar with the ​operation, according to the report. With one point being off the coast of Fujairah in the United Arab Emirates and the other off Oman’s port of Sohar. The operation involved at least 116 ships since it started in early May.In this picture obtained from Iran's ISNA news agency on June 1, 2026, vessels sail at Suru Beach in Bandar Abbas along the Strait of Hormuz.

Whether both sides are close to never having to use this method again, will be revealed this Friday in Geneva.
