US Tanker Heads to Middle East

A U.S.-sanctioned tanker was tracked heading into the Gulf this month even as Washington said it was blocking ships tied to Iranian ports. (usnews.com) Reuters reported on April 16 that the very large crude carrier RHN entered the Gulf through the Strait of Hormuz, a day after the sanctioned tanker Alicia made the same passage. Kpler said Alicia was heading to Iraq, while RHN’s destination was not immediately clear. (thestar.com.my) A separate Reuters report on April 14 said at least three vessels, including two U.S.-sanctioned tankers, entered the Gulf on the first full day of the U.S. blockade on ships calling at Iranian ports. Another sanctioned tanker, Rich Starry, later turned back toward Hormuz after exiting the Gulf. (al-monitor.com, usnews.com) That is why ship-tracking screenshots keep spreading online: open-source monitors are watching whether actual tanker movements match the U.S. enforcement line. AIS, the radio system ships use to broadcast identity and position, lets analysts and traders follow those routes in near real time. (marinetraffic.com, vesselfinder.com) The waterway at issue is small and central to the oil trade. The International Energy Agency says about 20 million barrels a day, or roughly 25% of world seaborne oil trade, move through the Strait of Hormuz, with about 80% of that oil bound for Asia. (iea.org) Traffic through the strait has also been erratic. Kpler data cited by Reuters showed more than 20 vessels passed on April 19, the highest count since March 1, but Windward said transits then dropped to just three vessels on April 20, the lowest level since the blockade began. (al-monitor.com, windward.ai) The U.S. pressure campaign widened again on April 21. The Pentagon said U.S. forces boarded the stateless tanker M/T Tifani in the Indo-Pacific, outside the Gulf itself, as part of enforcement against vessels linked to Iranian oil smuggling. (stripes.com, ocregister.com) Iran and shipping groups have treated those moves as a warning that the risk now extends beyond Hormuz. Bloomberg reported commercial traffic was near a standstill after the first U.S. seizure of an Iranian vessel, while Windward said 870 vessels remained in the Gulf under continued caution. (bloomberg.com, windward.ai) So the tanker posts are not just about one ship. They are being read as a live test of whether sanctions, naval enforcement and commercial oil flows can all operate at the same time in the world’s busiest energy chokepoint. (iea.org, usnews.com)
