ITF Official Data Shows Historic Increase in Abandonment of Ships, Direct Impact on Thousands of Mariners, and Rising Environmental Concerns on Routes Under International Sanctions.

In 2025, therefore, the abandonment of tankers and commercial vessels reached a record level. According to a report released in December 2025 by the International Transport Workers’ Federation (ITF), there were 410 abandoned ships recorded worldwide. In comparison, in 2016, only 20 cases had been accounted for. Thus, the growth has become significant and documented.

Furthermore, according to data consolidated by the ITF throughout 2025, more than 6,000 sailors were directly affected. Consequently, the crisis has ceased to be an isolated event and has become a global trend in maritime transportation.

Immediate Impact on Crews

First, abandonment does not only involve the vessel. On the contrary, it involves workers left without wages, supplies, and legal assistance. According to the ITF, Indian sailors represent the largest affected group, with more than a thousand cases reported in 2025.

For example, in November 2025, a deck chief identified as Ivan reported to the BBC shortages of basic food supplies on board. According to the account, there was a lack of meat, grains, and fish for weeks. Additionally, the ship remained outside Chinese territorial waters, without permission to dock.

Ghost Fleets and Sanctioned Market

At the same time, the term “ghost ships”, also known as “zombie ships,” gained traction. These tankers operate with opaque corporate structures. Thus, they manage to circumvent financial and regulatory restrictions.

Since February 2022, when the war in Ukraine began, a parallel market has formed for transporting oil from countries under sanctions, such as Russia, Iran, and Venezuela. Consequently, older vessels have become strategic assets.

In general, they are tankers with about two decades of use, close to being dismantled. Therefore, they are acquired for quick operations, without structural investments. Moreover, many do not have full coverage from P&I Clubs, which increases financial and environmental risks.

Flags of Convenience and Regulatory Gaps

In addition, according to the ITF itself, 82% of the abandonments recorded in 2025 occurred under flags of convenience. In this model, the owner registers the ship in a country different from their own to obtain more flexible regulation.

Among the main states are Panama, Liberia, and the Marshall Islands, responsible for 46.5% of the global merchant fleet. However, Gambia drew attention in 2023 by rising from zero to 35 vessels registered under its flag.

According to recent reports from the International Maritime Organization (IMO), many of these countries outsource technical inspections. Therefore, oversight may become limited, especially for older vessels.

Environmental Risk and Operational Safety

Meanwhile, the case cited by Ivan illustrates the extent of the risk. The ship is carrying 750,000 barrels of Russian oil, valued at around US$ 50 million. The vessel departed from the Russian Far East in early November 2025.

Since then, it has remained near its final destination, without docking. Thus, experts warn of the potential for environmental leakage. Furthermore, consolidated statistics indicate that more than 80% of maritime accidents involve human error.

In December 2025, the ITF intervened to provide overdue wages, food, and began planning for repatriation.

Institutional Responses and Need for Regulatory Review

Although there are isolated initiatives, the phenomenon remains global. For example, India included 86 foreign ships on a blacklist for abandoning crew members and violating labor rights.

At the same time, some states are pressuring countries that operate under flags of convenience. However, experts advocate for greater international regulatory harmonization.

This content was prepared based on nominal data from the ITF, BBC, and reports from the International Maritime Organization published between 2023 and 2025. The information has been reviewed to ensure accuracy and editorial transparency.

Given this scenario documented by official entities, will the international maritime community be able to strengthen oversight and protection mechanisms for sailors in the coming years?
