The shadow fleet is a collection of aging and often poorly maintained vessels with unclear ownership structures and lack of insurance. The number of old, outdated ships departing from Russia has increased dramatically. The EU has recently introduced legislation aimed at cracking down on the sale of mainstream tankers into the Russian shadow trade, but the problem persists. Russia managed to expand its shadow tanker fleet, adding 35 new tankers to replace 41 tankers added to OFAC’s SDN list since December 2023. These tankers, all over 15 years old, are managed outside the EU/G7. With 85% of the tankers aged over 15 years, the risk of oil spills at sea is heightened.
