Russia's "shadow fleet" of oil tankers has expanded dramatically, now comprising approximately 17% of all in-service oil tankers globally. This clandestine fleet, which numbered 940 ships as of earlier this year, has seen a 45% increase in size over the past year, according to a social media post by Peter Baker, referencing Jeanna Smialek. Its primary purpose is to circumvent international sanctions and facilitate the continued sale of Russian oil on the global market.
The rapid expansion of this fleet underscores Russia's adaptive strategies to maintain its crucial oil revenues despite Western economic restrictions. Estimates from maritime intelligence firms indicate that the broader shadow fleet, including various vessel types, has grown to approximately 1,800 ships, with around 600 dedicated tankers, as of 2024. These vessels often operate with opaque ownership structures, utilize older ships, and frequently bypass traditional maritime insurance and regulatory oversight.
Operations within the shadow fleet involve various tactics to avoid detection and enforcement, including disabling transponders, engaging in illicit ship-to-ship transfers, and relying on non-Western insurance providers. The average age of these tankers, often exceeding two decades, raises significant concerns regarding maritime safety and potential environmental hazards, particularly in sensitive waterways. Such practices increase the risk of accidents and oil spills.
The proliferation of these unregulated tankers significantly impacts the global oil market, creating a parallel shipping infrastructure that undermines international efforts to stabilize prices and enforce environmental standards. This network allows Moscow to sustain substantial revenues, despite the intended financial squeeze of the G7 price cap, by continuing to export oil, primarily to Asian markets. The use of these vessels challenges the effectiveness of sanctions by enabling Russia to sell oil, albeit often at discounted rates.
The substantial increase in vessel numbers demonstrates Russia's persistent efforts to adapt to economic pressures, indicating a complex and evolving landscape in global oil trade and sanctions enforcement. The growing size and operational methods of the shadow fleet present an ongoing challenge for international bodies seeking to monitor and regulate maritime commerce and enforce sanctions effectively.
