Bernhard Schulte Shipmanagement (BSM) is to remove its crews from two crude tankers linked to Venezuelan state-owned oil company PDVSA after a stand-off over pay.

The amount owed by PDVSA’s shipping subsidiary PDV Marina to BSM globally is at least $15m, sources told Reuters.

BSM said crews will be removed from the suezmax Rio Arauca (built 2011) and aframax Parnaso (built 1993), which are both currently anchored in Lisbon, Portugal.

The 158,800-dwt Rio Arauca, which is owned by Horizon Tankers of Greece, was on long-term charter to PDV Marina before its bunkers were arrested for unpaid invoices.
