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.

Key Insight
“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.”
