Fraud-hit Aegean Marine Petroleum Network has filed for voluntary Chapter 11 bankruptcy restructuring in the US.

The bunker and tanker company, and certain of its subsidiaries, said the process will be carried out in bankruptcy court of the southern district of New York.

Support will be given by key strategic partner Mercuria Energy Group, the energy and commodities company.

Mercuria is providing more than $532m in post-petition financing to fund the restructuring and Aegean's working capital needs.
