The Dark Fleet: A Growing Concern in Global Oil Trade
The “dark fleet,” comprised of oil tankers that evade detection and sanctions, is a growing concern in the global oil trade.
When maritime tracking maps suddenly show an oil tanker vanishing from the ocean, only to reappear days later near a refinery thousands of miles away, analysts often suspect the work of the so-called “dark fleet.” These vessels are sometimes described as “ghost ships” of the global oil trade: tankers that deliberately disappear from monitoring systems, change identities, and secretly move billions of dollars’ worth of sanctioned crude across the world’s oceans.
India‘s First Major Move Against the Dark Fleet
In one of its first visible actions against the shadow shipping network, the Indian Coast Guard seized three oil tankers near Mumbai suspected of involvement in international oil smuggling. Officials said the vessels were part of an illicit trading network and were known for frequently changing their identities, a common tactic used by dark fleet ships.

The ships were escorted to Mumbai for investigation. Maritime intelligence platforms later identified them as tankers linked to sanctioned oil trades, including shipments connected to Iran.
What Exactly Is the Dark Fleet?
The dark fleet, also known as the shadow fleet, is a global network of aging oil tankers used to transport sanctioned crude from countries such as Russia, Iran, and Venezuela. Analysts estimate the network now includes around 1,400–1,500 vessels, representing a significant portion of the global tanker fleet.
These ships operate outside the normal regulatory framework of international shipping. Many have unclear or fake ownership structures, questionable flag registrations, limited or no insurance, and poor maintenance standards. Despite these risks, they continue to move large volumes of crude because sanctioned oil often sells at deep discounts, making it attractive to buyers.
How Ghost Tankers “Disappear”
To evade detection and sanctions enforcement, dark fleet vessels rely on several deceptive tactics.
1. Turning Off Tracking Systems
All commercial ships are supposed to broadcast their location through the Automatic Identification System (AIS), a satellite-based tracking signal used to prevent collisions and monitor shipping routes. Dark fleet tankers frequently switch off their AIS transmitters, disappearing from satellite tracking maps for days or weeks at a time. During this “dark period,” the ship may load or unload oil without being detected.
2. Spoofing Their Location
Some vessels go even further by spoofing their GPS location, transmitting false coordinates that show them sailing in completely different areas, sometimes thousands of kilometres from their actual position. This tactic makes it harder for regulators and analysts to track their movements.
The U.S. has announced the seizure of the Bella-1 for violations of U.S. sanctions. The vessel, known as the Marinera after recently reflagging to Russia, was seized in the North Atlantic pursuant to a warrant issued by a U.S. federal court.
