The Amber: Crew Feedback and Vessel Data

The Iranian-affiliated tanker 'Amber' has made a notable reappearance on the Automatic Identification System (AIS) near the U.S. blockade boundary, just outside the eastern entrance of the Strait of Hormuz. This reintegration follows the Memorandum of Understanding outlined on June 14, 2026, albeit with limited movement data accessible. On June 16, the tankers 'Diona' (IMO: 9569695) and 'Hero 2' (IMO: 9362073) maneuvered past the U.S. Navy blockade line at the eastern extremity of the Gulf of Oman. Shortly thereafter, the 'Sonia I' (IMO: 9357365) joined them, marking a significant uptick in Iran's crude oil exports after a two-month hiatus. While the legal circumstances surrounding these movements remain ambiguous, the almost simultaneous activation of four fully loaded tankers implies strategic decision-making by operators rather than mere isolated transactions.
