Polish refiner Orlen has in recent months chartered at least 10 tankers that previously shipped Russian oil to Asia to deliver Arab crude to its refineries in Lithuania and Poland on their return journey, according to two traders and LSEG data. Many oil majors have avoided contracting tankers that have carried Russian crude because of the risk of sanctions and self-imposed restrictions. Using the tankers operated by non-Russian shipping firms, but delivering Russian oil and products is not in breach of any sanctions, but the shipments are subject to the price cap policy imposed by the Group of Seven (G7) leading economies.
