- Three Liberian-flagged oil tankers were struck by unknown projectiles while transiting the Strait of Hormuz on Tuesday, according to shipping intelligence service Marisks.
- The vessels had their Automatic Identification System transponders turned off to avoid detection, as reported by Marisks.
- UKMTO received three separate time-late third-party reports of attacks on tankers in the Strait of Hormuz, including one that caused a fire on Monday evening.
- The fire from the Monday incident has since been extinguished, and the vessel is underway with all crew safe.
- Marisks identified the tankers as Al Ruwais, Mersin Prosperity, and Sinbad, managed by ADNOC Logistics & Services and Anglo-Eastern Tanker Management.
- Al Ruwais was last seen conducting a ship-to-ship transfer off Sohar, Oman, in late September to discharge its diesel cargo.
- Mersin Prosperity also made a ship-to-ship transfer off Sohar in mid-September to move 2 million barrels of Iraqi Basrah crude onto another vessel.
- Sinbad loaded refined products at Saudi Arabia's Jubail industrial port in early September.
Three Liberian-flagged oil tankers were struck by unknown projectiles while transiting the Strait of Hormuz on Tuesday, as reported by shipping intelligence firm Marisks. The vessels, including the oil products tanker Al Ruwais and the very large crude carrier Mersin Prosperity, had their Automatic Identification System transponders turned off to avoid detection.1567
The United Kingdom Maritime Trade Operations (UKMTO) received three separate time-late reports of attacks on tankers in the strait, with one incident resulting in a fire on a vessel, which has since been extinguished. All crew members are reported safe.34

According to Marisks, the tankers were also identified as the Aframax-sized tanker Sinbad, managed by Anglo-Eastern Tanker Management. The Al Ruwais was last seen conducting a ship-to-ship transfer off Sohar, Oman, in late September, while the Mersin Prosperity moved 2 million barrels of Iraqi Basrah crude in mid-September.8
Despite reports indicating that oil flows through the Strait of Hormuz have recovered, operational risks remain high, and the strait is not as open to traffic as many believe. ADNOC Logistics & Services, which manages the Al Ruwais and Mersin Prosperity, declined to comment on the incidents.
“The tankers had their Automatic Identification System transponders turned off to avoid detection, according to Marisks. UKMTO had earlier warned of three separate attacks, including one that caused a fire, which was extinguished with all crew safe.”
