US Seizes Fifth ‘Ghost Fleet’ Tanker in the Caribbean as Venezuela Oil Blockade Tightens

US forces have seized another oil tanker in the Caribbean Sea, the fifth ship taken in Washington’s growing campaign to control Venezuela’s oil trade. The tanker, called the Olina, was boarded before dawn on Friday, 6 November 2026, in the latest move in a naval operation that is reshaping how Venezuelan oil reaches the world.

The seizure shows how far the United States is willing to go to enforce its blockade on sanctioned Venezuelan oil. Warships, Marines, helicopters and the Coast Guard are now all involved, and American officials say there is “no safe haven” for ships that try to break the rules.

This article explains what happened, who the Olina is, what the “ghost fleet” means, and what could happen next.

What happened in the Caribbean

In the early hours of Friday, US Marines and Navy sailors launched from the aircraft carrier USS Gerald R. Ford boarded the Olina in the Caribbean Sea. The US Coast Guard then took control of the vessel. The operation was carried out without incident, and the crew is cooperating with US forces, according to US officials.

The US Southern Command, which oversees American military operations in the region, announced the seizure on social media. It declared that “there is no safe haven for criminals”. The command also posted unclassified video of a US helicopter landing on the tanker and American personnel searching the deck.

Homeland Security Secretary Kristi Noem also posted about the operation. She described the Olina as “another ‘ghost fleet’ tanker ship suspected of carrying embargoed oil” and said it had departed Venezuela “attempting to evade US forces”.

President Donald Trump later said on his social media network that the seizure was conducted “in coordination with the Interim Authorities of Venezuela”, though he gave no further details.

The Olina is the fifth tanker seized by US forces as part of the Trump administration’s effort to control the production, refining and global distribution of Venezuela’s oil products. That effort followed the US ouster of President Nicolás Maduro in a surprise nighttime raid earlier this year.

The ship at the centre of the seizure

The Olina has a complicated past, and that past is a big part of why American officials targeted it.

According to shipping records and industry sources, the tanker formerly sailed under the name Minerva M. Under that name, it was sanctioned by the United States for moving Russian oil. It was previously flagged in Panama.

At the time of the seizure, the ship was flying the flag of Timor-Leste. But public shipping registries list that flag registration as false — meaning the registration the ship claims is not valid. Changing names and flags is a common tactic among ships that try to move sanctioned oil without being caught.

The Olina had also been “running dark”. Satellite tracking data showed that the ship’s automatic identification system — the beacon that tells other ships and authorities where a vessel is — had last been active 52 days earlier, near Venezuelan waters northeast of Curaçao. After that, it switched the beacon off and sailed without broadcasting its location.

Authorities said the Olina had left Venezuela fully loaded and was returning to the region when it was intercepted.

Samir Madani, co-founder of the ship-tracking group TankerTrackers.com, estimated that the Olina is carrying about 707,000 barrels of oil. At a market price of around $60 a barrel, that cargo would be worth more than $42 million.

What is the “ghost fleet”?

The term “ghost fleet” — also called the shadow fleet or dark fleet — describes a large group of ageing tankers that move oil from countries under sanctions, including Venezuela, Russia and Iran. The ships often operate with little regulation, unclear ownership and, in many cases, no known insurance.

These vessels use a set of tricks to hide what they are doing:

• False flags: They fly the flag of a country they are not really registered in, so it is harder for authorities to know who is responsible for them.
• Going dark: They switch off their location beacons, so satellites and other ships cannot track them.
• Name changes: They change names and owners on paper, sometimes through a chain of shell companies in different countries.
• Ship-to-ship transfers: They move oil from one tanker to another in the open sea, which makes it hard to prove where the oil originally came from.

US officials say these ships are part of a broader attempt to evade sanctions and move Venezuelan oil illegally. The Olina fits that pattern: a sanctioned ship, a false flag, a switched-off beacon, and a cargo of Venezuelan crude.

The fleet is large. TankerTrackers.com says it used satellite images and photos taken at sea level to document at least 16 tankers leaving the Venezuelan coast in defiance of the quarantine that US forces have set up to block sanctioned ships from trading. The Olina was one of that group.

Operation Southern Spear and the blockade

The seizures are part of a US naval campaign called Operation Southern Spear. The operation is run by Joint Task Force Southern Spear and is aimed at enforcing a blockade on sanctioned Venezuelan oil shipments.

The United States has built up a large force in the Caribbean in recent months, centred on the aircraft carrier USS Gerald R. Ford. Earlier this month, US forces also seized another tanker, the M Sophia, and pursued other vessels tied to similar oil-moving operations. Several tankers turned back toward Venezuelan waters to avoid being stopped, Pentagon officials said.

American officials have said the blockade applies “anywhere in the world” and that the United States will keep watching and stepping in where it believes it is needed. The future of other tankers now sailing toward Venezuelan ports is unclear, but the message from Washington is that more seizures are possible.

The operations are also part of a wider effort to enforce sanctions and disrupt illicit trade at sea, which US officials say undermines the law and regional security.

Why Venezuela’s oil matters

Oil is Venezuela’s most important export and its main source of foreign income. For years, the country has sold its crude through a mix of legal and hidden channels, even while under US sanctions. Whoever controls that oil trade has real power over Venezuela’s economy — and over the government in Caracas.

That is why the tanker seizures matter beyond the ships themselves. Each seizure takes a cargo of oil off the market, sends a warning to other ship owners, and tightens the squeeze on the money flowing to and from Venezuela’s oil sector.

The campaign also matters for the wider world. Venezuela holds some of the largest proven oil reserves on the planet. When its exports are disrupted, traders and governments watch closely to see whether global oil supplies and prices are affected. So far, the seizures have targeted individual ships rather than the whole flow of oil, but the scale of the operation — a carrier strike group, repeated boardings, and a declared global blockade — shows that Washington sees the oil trade as a central part of its Venezuela policy.

For countries that buy oil, including Pakistan, the key question is whether the crackdown pushes prices up. There is no clear answer yet, and much depends on how many more ships are seized and how Venezuela and its buyers respond.

What happens next

Several questions will shape what comes next:

• More seizures? With at least 16 tankers documented leaving Venezuela in defiance of the quarantine, and the US saying the blockade applies worldwide, further boardings look likely.
• What happens to the Olina? The Coast Guard has taken control of the ship. US authorities have not said where it will be taken or what will happen to its cargo, but in earlier seizures the United States has moved to sell seized oil.
• How will other ships react? Several tankers have already turned back to Venezuelan waters rather than risk being stopped. Others may keep trying to run the blockade, switch off their beacons, or change flags again.
• What about Venezuela’s interim authorities? Trump said the Olina seizure was coordinated with Venezuela’s interim authorities. How that relationship works in practice — and what it means for the future of the country’s oil industry — is still unclear.
• Will the blockade spread? US officials describe the campaign as part of a broader effort to enforce sanctions and disrupt illicit trade at sea. The pattern suggests Washington is willing to use force at sea to enforce sanctions in more than one region.

Why it matters

The seizure of the Olina is a small event on its own — one ship, one cargo, one morning in the Caribbean. But it is part of something much bigger: a US decision to use military force to control who can buy and sell Venezuelan oil.

For ordinary people, the effects may show up in oil prices, in the politics of Latin America, and in the way countries under sanctions find ways to keep trading. For the shipping world, the message is simple: a false flag and a switched-off beacon are no longer enough to stay hidden.

The Caribbean has become the front line of that fight, and the Olina is unlikely to be the last ship seized there.
