By Nerijus AdomaitisOct 3 (Reuters) – The Boracay, a tanker under Western sanctions on suspicion of being part of Russia’s “shadow fleet” and also facing a separate investigation by French authorities, has set sail from where it was anchored off western France, according to MarineTraffic data. Neither local French maritime authorities, nor the Brest prosecutor’s office, which has been investigating the Benin-flagged vessel over its nationality, responded to requests for comment. Prior to its detention, the Boracay was destined for India’s Vadinar port, home to a Nayara Energy refinery. French President Emmanuel Macron said on Thursday that the ship was detained as part of a European strategy to combat the oil revenue stream that helps to fund Russia’s war efforts in Ukraine. To try to skirt Western sanctions, Russia has been increasingly relying on old vessels, known as the shadow fleet, to ship its oil and gas.
