What’s inside?

Executive Summary

This case examines a 30-year-old tanker that appeared to have reached the end of its operational life after entering the Gadani Scrapyard in Pakistan in 2021. After four years of inactivity consistent with scrapping, the vessel unexpectedly re-emerged in late 2025 under a new flag and identity. Since resurfacing, it has exhibited a pattern of prolonged AIS dark activity and repeated voyages to Iran – behavior consistent with high-risk maritime operations. The vessel is currently operating in Iranian waters, reporting an invalid AIS destination.

Phase 1: Entry into the Scrapyard (2021)

On March 23, 2021, the tanker – then approximately 30 years old and sailing under the Saint Kitts and Nevis flag – entered the Gadani Scrapyard, one of the world’s largest ship-breaking facilities.

Satellite imagery captured on March 26, 2021, shows the vessel anchored within the scrapyard area. Two days later, on March 28, it formally called port at the scrapyard, a step that typically marks the irreversible end of a vessel’s commercial life. Vessels entering Gadani are usually dismantled for scrap, so re-entry into global trade after such a call is extremely rare.

From that point onward, the vessel disappeared from normal commercial shipping activity, consistent with scrapping or abandonment.

Phase 2: Re-Emergence and Identity Reset (October 2025)

After nearly four years of inactivity, the vessel resurfaced on October 3, 2025, effectively returning “from the dead.”

Upon reappearance, the tanker:

Changed its MMSI.
Reflagged to the Marshall Islands.
Re-entered AIS transmission in the Malacca Strait, a major global shipping chokepoint.

Rather than resuming normal commercial trade, the vessel immediately adopted a high-risk operational profile. It sailed directly toward Iran and, upon arrival, entered a five-day AIS dark period. This is a common tactic used to conceal port calls and cargo operations in sanctioned jurisdictions.

Phase 3: Repeated Dark Activity and Pattern Obfuscation (Late 2025 – Early 2026)

After the initial Iran call, the vessel returned toward Malaysia, close to the location where it had first reappeared. What followed was a highly irregular AIS pattern:

A three-month continuous dark period.
A brief 15-minute AIS re-emergence.
An additional 14-day dark period.

Such short, intermittent reappearances are often used to reset tracking systems, test monitoring thresholds, or create ambiguity around true movement and port activity.

On February 6, 2026, the vessel re-emerged in the Indian EEZ, after which it began a direct transit back toward Iran.

Phase 4: Return to Iran and Current Status (February 2026)

The tanker entered Iranian waters on February 15, 2026, where it remains at present.

The vessel is currently:

Operating under a Marshall Islands flag.
Assessed as having Iran sanctions compliance risk.
Flagged as high risk for smuggling.
Broadcasting an invalid AIS destination (“FKR”).
Positioned near the Strait of Hormuz, one of the most strategically sensitive maritime corridors globally.
Still reported as a “dead vessel”.

Assessment: Why This Vessel Matters

This case is notable not because of a single risk indicator, but because of the stacking of anomalies:

A vessel that entered a scrapyard and later returned to service.
Identity laundering via flag and MMSI changes.
Extended and repeated AIS dark periods.
Direct operational linkage to Iran.
Non-credible AIS reporting.

Individually, any one of these indicators might be explainable. Together, they form a coherent picture of intentional concealment and high-risk activity, consistent with patterns observed in sanctions-evasion networks and gray-fleet operations.

Zombie Vessel or Dead Vessel?

The term “zombie vessel” refers to an active ship operating under the stolen or recycled identity of a defunct or scrapped vessel. In these cases, a different physical ship assumes the IMO number, name, or flag of a vessel that has been deregistered, dismantled, or declared inactive. This form of maritime identity laundering allows sanctioned actors to bypass static compliance checks by exploiting the legitimacy of a previously registered ship.

A “dead vessel,” by contrast, is the original physical vessel itself returning to service after being presumed scrapped, dismantled, or permanently withdrawn from commercial activity. In this scenario, the hull is not replaced – the ship itself re-enters operations, often after opaque refurbishment, identity modification, or regulatory manipulation.

The distinction matters operationally. A zombie vessel involves identity theft at the data layer. A dead vessel involves the physical resurrection of a hull that was expected to be dismantled. Both tactics undermine compliance systems, but they require different investigative approaches and carry different implications for ownership tracing, liability, and enforcement action.

In this case, satellite imagery confirms the presence of a tanker with general physical characteristics consistent with the vessel that entered the Gadani Scrapyard in 2021. Notably, imagery captured prior to the scrapyard entry and imagery captured following the vessel’s re-emergence show a tanker of the same approximate length, with a similar cross-like structural pattern visible on the deck. However, based on currently available information, it is not yet possible to determine definitively whether this is the original hull returning to service (a dead vessel) or a different tanker operating under a recycled identity (a zombie vessel).

Comparative satellite imagery: The vessel documented at Gadani Scrapyard in March 2021 (left) and the tanker active in October 2025 (right) exhibit comparable length and a similar cross-deck structural layout. These similarities suggest continuity, but do not provide conclusive proof of hull identity.

What is clear is that the vessel’s re-emergence following a scrapyard call, combined with identity changes, prolonged AIS dark periods, and repeated voyages to Iran, aligns with broader patterns of maritime identity manipulation observed in sanctions-evasion networks. Whether zombie or dead, the operational effect is the same: concealment of ownership, obfuscation of trade flows, and circumvention of static screening systems.

Strategic Implications

The reactivation of a vessel presumed scrapped underscores a broader trend: the recycling of obsolete tankers into opaque, high-risk supply chains supporting sanctioned states. These vessels often operate outside traditional insurance, financing, and compliance frameworks, increasing environmental, safety, and geopolitical risk – particularly in chokepoints like the Strait of Hormuz.

This case illustrates how behavioral analysis and long-term vessel history are critical to identifying threats that would be missed by static vessel attributes alone.
