By Tsvetana Paraskova of OilPrice.com

Iran’s first observed crude oil exports in two months have moved past the US blockade outside the Strait of Hormuz in a sign that Iran is wasting no time to take advantage of the tentative deal with the United States.

Following the announcement of the deal this weekend, and ahead of a formal signing ceremony expected in Switzerland on Friday, at least three Iranian crude oil tankers have exited the Strait of Hormuz and departed from the region moving past the U.S. blockade so far this week, tanker-tracking firms have said.

TankerTrackers.com has estimated through AIS data corroborated by satellite imagery that at least two supertankers of the National Iranian Tanker Company (NITC) have moved through the U.S. blockade. The very large crude carriers (VLCCs), named Diona and Hero2, have kade perimeter carrying a combined total of 3.8 million barrels of Iranian crude oil between them, TankerTrackers.com said.

“These are Iran's first crude oil exports in two months,” the ship-tracking service said.

Another tanker of the National Iranian Tanker Company, the Stream, is approaching the U.S. blockade line from the exclusive economic zone of Pakistan, where she spent the past 7 weeks waiting to enter Iran, according to TankerTrackers.com.

Kpler has observed a third Iran-linked tanker carrying 1 million barrels of Iranian crude that exited the blockade line on Wednesday.

“Iran is wasting no time getting its tankers back into circulation,” said Michelle Wiese Bockmann, senior maritime intelligence analyst at Windward.

The VLCC Dan of the NITC has left the area near the Riau archipelago where it has been dark since May 23 and is now heading to Iran for loading, Bockmann added.

The Iranian oil tanker traffic is intensifying, with the deal that would launch 60-day negotiations set to be signed in Geneva on Friday. In addition, Iran is preparing to take advantage of the U.S. allowing Iranian oil sales immediately upon signing of the agreement. Under the agreement expected to formally end the war between the United States and Iran, Tehran will be allowed to immediately resume oil and fuel sales, the Wall Street Journal reported on Tuesday, citing people familiar with the details of the deal.
