U.S. Threats Fail to Stop Cuban Oil Supply
Tanker carries 730,000 barrels of crude oil to address Cuba's oil shortage.
Cuba has no oil since January, leading to emergency conservation measures.
Oil can produce 250,000 barrels of diesel for 12.5 days of demand.
Processing crude takes 15-20 days, with 5-10 days for delivery.
U.S. government struggles to block oil once tanker enters Cuban waters.
