Two liquefied natural gas tankers are exiting the Strait of Hormuz and heading to Pakistan and China, while a supertanker carrying Iraqi crude for China has also left the Gulf after being stranded for nearly three months, according to shipping data, signaling limited movement through one of the world’s most critical energy chokepoints.

Traffic through the strait has been sharply disrupted by the US-Israeli war on Iran, which began on Feb. 28 and has severely curtailed shipping through the narrow waterway that normally handles about a fifth of global oil and LNG supplies.

The vessels are among only a small number of tankers to have exited the Gulf this month using a transit route Iran has ordered ships to follow. Last week, three Very Large Crude Carriers carrying about 6 million barrels of oil also made their way through the strait bound for China and South Korea.

LNG tanker Fuwairit was crossing the Strait of Hormuz on Monday and is expected to discharge its cargo in Pakistan on Tuesday, according to data from LSEG and Kpler. The Bahamas-flagged vessel loaded LNG at Qatar’s Ras Laffan port around March 28.

Another LNG tanker, Al Rayyan, has also exited the strait. The vessel, carrying cargo loaded at Ras Laffan, was last seen in the Gulf on May 22 and is now positioned outside the waterway between Iran and Oman. It is scheduled to discharge in China on June 27, according to the shipping data.

Separately, the VLCC Eagle Verona exited the strait on Saturday and is expected to arrive at Ningbo port in eastern China on June 12 to discharge its cargo. The Singapore-flagged vessel, chartered by Unipec, the trading arm of Sinopec, loaded nearly 2 million barrels of Basrah crude around Feb. 26, the data showed.

The Eagle Verona was among seven ships for which Malaysia had sought transit permission from Iran, according to earlier reports. Five of those vessels have now exited the waterway, while two remain in the Gulf.

Before the conflict began, daily traffic through the Strait of Hormuz averaged between 125 and 140 passages. The disruption has left about 20,000 seafarers stranded inside the Gulf aboard hundreds of vessels.
