Greek shippers Minerva Marine, Thenamaris and TMS Tankers have stopped transporting Russia oil in recent weeks, the four traders said. The Greek shippers' exit from the trade followed tighter U.S. sanctions imposed on Russian oil shipments. The G7 countries introduced a price cap on Russian oil in late 2022, but had not previously enforced it. Russian oil trade has brought record revenues over the past year to the shippers who took the risk and stayed in the business.
