The Dubai-based ship manager newly sanctioned by the European Union has been linked to a ship-to-ship transfer of Urals crude in the Mediterranean in January with a tanker that went “dark”.

The 109,300-dwt Sakhalin Island (built 2004), managed by Sun Ship Management, transferred its cargo off the coast of Greece to a second vessel that that did not transmit its position for several days, according to data analyst Vortexa.
