A voyage by a Trafigura-controlled tanker into South America could signal a potential new market for Russian oil as the US struggles to export enough fuel to its usual markets.

The Trafigura-chartered 50,000-dwt Marlin Aventurine (built 2016) was reportedly booked to carry 262,000 barrels of diesel from Russia for Petroecuador in Ecuador in the run-up to the European Union ban on 5 December, sources told Bloomberg.
