Engineering company Galvao Engenharia has filed for bankruptcy following the Petrobas scandal.
The firm had its payments cut off by the state-run oil company following an alleged corruption scheme.
However Grupo Galvao, the firm’s parent company, said it had no part in the alleged corruption involving Petrobas.
Galvao will have 60 days to present a recovery plan.
The company claimed it was owed more than $150million by Petrobas for work it had already undertaken.
Petrobas has been hit by the widening corruption scandal surrounding the company.
At least $800million was paid in bribes and other funds by the nation’s biggest construction and engineering firms in exchange for inflated Petrobras contracts.
