CARACAS: At least four tankers, most of them loaded, that had departed from Venezuela in early January in ‘dark mode’ — or with their transponders off amid a strict US blockade — are now back in the South American country’s waters, according to state company PDVSA and monitoring service TankerTrackers.com.

A flotilla of about a dozen loaded vessels and at least three other empty ships left Venezuelan waters last month in apparent defiance of an embargo imposed ⁠by US President Donald Trump since mid-December, which has dragged down the country’s oil exports to minimum.

One of the ships, the Panama-flagged supertanker M Sophia, was intercepted and seized by the US this week when returning to the country; while another, the Aframax tanker Olina with a flag from ⁠Sao Tome And Principe, was intercepted but released to Venezuela on Friday, state company PDVSA said.

Three more of the vessels that had departed in that flotilla, Panama-flagged Merope, Cook Islands-flagged Min Hang and Panama-flagged Thalia III, were spotted by Tankertrackers.com in Venezuelan waters late on Friday through satellite images.

US authorities had said on Friday that Olina -previously known as Minerva M — would be freed. The next step for the country, which remains under strict US ⁠supervision after it captured and extracted President Nicolas Maduro last week, would be the beginning of organized crude exports as part of a $2 billion oil supply deal Caracas and Washington are negotiating, they said.
