Russian fuel supplier Big Port Service is appealing a US court decision in what could be the final battle over China Cosco Shipping's exposure to the 2014 OW Bunker collapse.

Big Port’s attorney, Peter Skoufalos of law firm Brown Gavalas & Fromm, notified the federal court for the Southern District of New York of the appeal last week.

He is asking the Second Circuit appeals court to overturn a January ruling in favour of Cosco affiliate China Shipping Container Lines (CSCL).
