Iran blacklists more ships trying to sail through Hormuz, govt website shows

The U.S. imposed sanctions on the PGSA in May, complicating any engagement with the body which could result in asset freezes by the U.S. Treasury if any transactions or fees are paid.

Some of the named ships previously hit were owned by the United Arab Emirates' ADNOC Logistics and Shipping, ADNOC's subsidiary Navig8 Tankers, and Saudi Arabia's national shipping carrier Bahri.

After the announcement of the first blacklisted tankers, at least three Indian oil refiners and a global energy major planned to stop using the vessels due to security concerns, sources with direct knowledge of the matter told Reuters in late August.

The restrictions are likely to further constrain efforts to export oil via the strait, which before the war handled about 20% of global oil and liquefied natural gas shipments but has since seen traffic reduced mostly to a trickle.

The restricted list includes very large crude carriers, liquefied natural gas and liquefied petroleum gas tankers, and clean product vessels, among others.

"Any vessel cooperating with listed vessels (via STS oil transfers, transshipment) will be added to the list," the PGSA said on its website.

"To request removal, vessels must submit a formal application with justifications."

LONDON, Sept 2 (Reuters) - Iran has added more ships it deems as non-compliant and subject to fines, confiscation or detention if they try to sail through the Strait of Hormuz, according to a government website.
