Forbidden Russian oil flows into Pentagon supply chain

"After Western nations announced bans on Russian oil last year in response to the invasion of Ukraine, a Greek refinery that serves the U.S. military moved quickly to adapt. Within months, it told investors it had stopped accepting the forbidden oil and had found other sources instead. But there was a reason Russian petroleum, on paper at least, could so easily be removed from the supply chain.

Petroleum products that originated in Russia kept flowing to the Motor Oil Hellas refinery on the Aegean Sea in Greece, a Washington Post examination of shipping and trade data found. They just took a new route, hundreds of miles out of the way through an oil storage facility in Turkey, a journey that obscured Russia’s imprint as ownership of the products changed hands multiple times before they reached Greece.
On the surface, the refinery’s sourcing of fuel oil from the Dortyol shipping terminal in Turkey seemed to affirm pronouncements by the White House and European leaders that embargoes on Russian oil were working as planned, depriving President Vladimir Putin of crucial revenue to fund his military aggression in Ukraine. The fact that those shipments contained material that originated in Russia underscores the porousness of the sanctions and the failure to aggressively enforce them.
Over the past two years, Dortyol received 5.4 million barrels of fuel oil by sea, all but 1.9 million from Russia, according to shipping records and trade data from Refinitiv, a financial-data firm that specializes in commodities markets. Since the European Union sanctions took effect in February, Russian shipments to Dortyol totaled 2.7 million barrels, or more than 69 percent of the fuel oil shipped by sea to Dortyol during that period."
