An oil tanker seized by the US off the Venezuelan coast on Wednesday spent years attempting to sail the seas unnoticed.
Altering names, switching flags, and vanishing from monitoring methods.
That every one got here to an finish this week, when American coast guard groups descending from helicopters with weapons drawn stormed the ship, named Skipper.
A US official stated the helicopters that took the groups to the tanker got here from the plane provider USS Gerald R Ford.

The sanctioned tanker
Over the previous two years, Skipper has been tracked to international locations underneath US sanctions together with Iran.
TankerTrackers.com, which displays crude oil shipments, estimates Skipper has transported almost 13 million barrels of Iranian and Venezuelan oil since 2021.
And in 2022, the US Treasury Workplace of International Belongings Management (OFAC) positioned Skipper, then generally known as Adisa, on its sanctions listing.
However that didn’t cease the ship’s actions.

In mid-November 2025, it was pictured on the Jose Oil Export Terminal in Venezuela, the place it was loaded with multiple million barrels of crude oil.

It left Jose Oil Export Terminal between 4 and 5 December, in keeping with TankerTrackers.com.
And on 6 or 7 December, Skipper did a ship-to-ship switch with one other tanker within the Caribbean, the Neptune 6.
Ship-to-ship transfers permit sanctioned vessels to obscure the place oil shipments have come from.
The switch with Neptune 6 happened whereas Skipper’s monitoring system, generally known as AIS, was turned off.

Shifting within the shadows
Skipper has tried to go unnoticed by utilizing a way known as ‘spoofing’.
That is the place a ship transmits a false location to cover its actual actions.
“When we’re talking about spoofing, we’re talking about when the vessel manipulates the AIS data in order to present that she’s in a specific region,” Mr Ampatzidis defined.
“So you declare false AIS data and everyone else in the region, they are not aware about your real location, they are only aware of the false location that you are transmitted.”
When it was intercepted by the US, it was sharing a distinct location greater than 400 miles away from its precise place.

Skipper was manipulating its monitoring alerts to falsely place itself in Guyanese waters and fraudulently flying the flag of Guyana.
“It’s about the safety on the seas. As a shipping industry, we have inserted the AIS data, the AIS technology, this GPS tracking technology, more than a decade back, in order to ensure that vessels and crew on board on these vessels are safe when they’re travelling.”
Dozens of sanctioned tankers ‘working off Venezuela’
Skipper shouldn’t be the one sanctioned ship off the coast of Venezuela.
In accordance with evaluation by Windward, 30 sanctioned tankers have been working in Venezuelan ports and waters as of 11 December.

The tanker seizure is a extremely uncommon transfer from the US authorities and is a part of the Trump administration’s growing strain on Venezuelan President Nicolas Maduro.
In current months, the most important US army presence within the area in many years has constructed up, and a sequence of lethal strikes has been launched on alleged drug-smuggling boats within the Caribbean Sea and jap Pacific Ocean.
Prior to now, Mr Ampatzidis defined, actions like sanctions have had a restricted impact on illegally working tankers.
However the seizure of Skipper will ship a sign to different darkish fleet ships.
“From today, they will know that if they are doing spoofing, if they are doing dark activities in closer regions of the US, they will be in the spotlight and they will be the key targets from the US Navy.”
