According to reports in the leading Bulgarian news portal Dnevnik, Russian tankers Nikolay Veliki and Nikolay Gamayunov have been spotted refueling ships that are leaving Bulgaria’s Black Sea ports of Varna and Burgas. This activity takes place just outside the country’s 24-mile contiguous zone, raising questions about the implications for regional maritime operations. These "floating petrol stations" are effectively providing fuel to vessels in transit, which could affect the dynamics of shipping routes and energy supply in the area. The presence of these tankers has sparked discussions among local authorities and maritime experts about security and environmental concerns, particularly in light of the ongoing geopolitical tensions in the region. The situation highlights the increasing complexity of maritime operations in the Black Sea, especially as various countries navigate their interests amid shifting alliances and regulations.
