U.S. Forces Seize ‘Dark Fleet’ Tanker Skipper in Caribbean Raid Following AIS Spoofing Detection – SatNews
U.S. Coast Guard and special operations forces executed a high-seas seizure of the oil tanker Skipper off the coast of Venezuela on Wednesday, disabling a vessel that authorities described as a central node in an illicit “ghost fleet” transporting sanctioned crude.
The operation, launched from the aircraft carrier USS Gerald R. Ford, targeted the Very Large Crude Carrier (VLCC) after maritime intelligence confirmed it was broadcasting falsified Automatic Identification System (AIS) data to conceal its true location—a tactic increasingly common among vessels evading international sanctions.
Operation and Surveillance
While the vessel’s transponder broadcasted coordinates placing it near Guyana and Suriname, satellite imagery analysis by maritime intelligence firms, including Kpler and TankerTrackers.com, physically located the ship loading crude at Venezuela’s José terminal hundreds of miles away. This discrepancy highlights the sophistication of the tactics employed by these illicit operators.
The seizure of the tanker Skipper this week has thrust a shadowy maritime war into the spotlight. As sanctions against Russia, Iran, and Venezuela tighten, a parallel “ghost fleet” of vessels has emerged, employing increasingly sophisticated electronic warfare tactics to vanish from global tracking systems.
The Threat: Anatomy of a Ghost Fleet
A “ghost fleet” (or dark fleet) consists of vessels—often aging tankers nearing the end of their operational lives—that operate outside traditional insurance and regulatory frameworks to transport sanctioned crude oil. To evade detection, these operators employ a tiered system of obfuscation.
The simplest method, where a crew manually disables the Automatic Identification System (AIS) transponder. However, this creates a suspicious “gap” in data that modern algorithms immediately flag. Identity Laundering (“Zombie” Vessels): Operators purchase scrapped vessels’ Mobile Maritime Service Identity (MMSI) numbers and program them into active tankers. This allows a ship carrying sanctioned oil to masquerade digitally as a ship that was broken up years ago.
Flag Hopping: Rapidly changing vessel registration between “flags of convenience” (e.g., Cameroon, Palau, or Guyana) to outpace regulatory blacklists.
AIS Spoofing Mechanisms
While “going dark” is passive, AIS spoofing is active deception. It involves manipulating the ship’s broadcast data to place the vessel electronically in one location while it is physically hundreds of miles away. Circle Spoofing: A common anomaly where a vessel’s AIS signal broadcasts a perfect geometric circle or holding pattern. This is often a result of automated software generating fake coordinates to make the ship appear “busy” in safe waters while it conducts illicit ship-to-ship (STS) transfers elsewhere.
GNSS Manipulation: More advanced actors use devices to feed false Global Navigation Satellite System (GNSS) coordinates into the ship’s transponder. This allows a tanker to “jump” across oceans instantly or appear at a different location altogether, making it extremely difficult for authorities to track and intercept these vessels.
