Russian diesel shipment bound for Cuba challenges US blockade
Although limited in scale, the cargo —estimated at around 200,000 barrels of diesel— could cover roughly 10 days of national consumption
A Hong Kong-flagged tanker that could be carrying fuel to Cuba has resumed navigation in the Atlantic after remaining halted for several weeks, in a move that could offer limited relief to the island’s deepening energy crisis. According to ship-tracking available on Vessel Finder, the Sea Horse loaded fuel in a ship-to-ship operation earlier this year and then resumed course with Cuba as a possible destination. The Financial Times reported that the vessel was part of two Russian energy shipments headed to the island and could arrive within days.
The possible delivery comes at a critical time. Cuba reconnected its national power grid on Tuesday after a nationwide blackout lasting more than 29 hours, but officials warned that outages may continue because electricity generation remains below demand. The island had received only two small vessels carrying oil imports so far this year, as Washington steps up pressure to curb fuel shipments to Cuba.
Cuba’s energy crisis has worsened because of both supply shortages and structural decay. Monday’s collapse was the third major blackout in four months, with the Energy and Mines Ministry describing a “complete disconnection” of the national grid. An aging network, lack of maintenance and lower oil imports have all contributed to the system’s fragility.
At the same time, Moscow sharpened its diplomatic language. Russia said on Tuesday that it had “unwavering solidarity” with Cuba and condemned what it described as external interference and “illegal unilateral restrictive measures,” after President Donald Trump intensified pressure on Havana. The Kremlin said it remained in contact with Cuban leaders and was ready to provide assistance.
Although limited in scale, the cargo —estimated at around 200,000 barrels of diesel— could cover roughly 10 days of national consumption, according to specialist estimates. Its potential arrival would represent the first meaningful relief in weeks for an electricity system still operating under severe strain.
