U.S. authorities have stopped a ship traveling from Russia to Louisiana with a cargo of fuel products, say people familiar with the matter. The Daytona tanker is owned by Greek shipowner TMS Tankers Ltd. and was chartered by Vitol, a commodity trading house based in Switzerland. It sailed from Russia’s Taman peninsula in the Black Sea in early June carrying fuel oil and vacuum gasoil, the data showed, and was planning to arrive in New Orleans on Sunday.
