For Sinanju Tankers Holdings, the challenges laid bare by the OW Bunker collapse in 2014 remain unchanged, even as the resulting litigation fades.

The downfall of the Danish fuel oil trader highlighted the legal exposure that bunker tanker operators — as physical suppliers — face when engaged in their trade.

When the suppliers of the fuel that OW sold realised it was unlikely they would be able to get much out of the pile of ashes that the bunker giant had become, they sent their lawyers after the bunker tankers that delivered the fuel.
