Four Iranian tankers seen taking oil through Hormuz for first time since April

Four Iranian-flagged oil tankers passed through the Strait of Hormuz on Monday, a first since April 15 and the US blockade of Iranian ports, according to maritime tracking firm Kpler.

In data published on Thursday, the firm detected the passage of the Hilda I, the Amber, the Silvia 1, and the Happiness I, which were carrying a total of seven million barrels of oil.

They all loaded their cargo in mid-April on Kharg Island, the country’s main oil terminal, through which 90 percent of the Islamic Republic’s crude oil normally transits.

The ships crossed the strait on Monday with their AIS transponders turned off.

Kpler relies primarily on satellite imagery to track ships transporting raw materials.

The four oil tankers typically transport Iranian crude to an offshore area off the coasts of Malaysia and Singapore, where they transfer the cargo at sea to other tankers (ship-to-ship) tasked with delivering it to the final customer, often in China.

Tehran adopted this practice to circumvent international sanctions.

Three other oil tankers linked to Iran had already defied the blockade on April 15, according to Kpler. None had attempted to do so since then.
