Brazil's Petrobras shut its P-58 offshore oil production platform after the country's petroleum regulator ANP found safety problems on board, the state-run oil company said on Friday.

The platform was producing 106,000 barrels of oil and natural gas equivalent a day in January from seven wells, the last month for which oil regulator ANP has released statistics, making it the company's fifth-largest producer.

The platform was shut down on Wednesday, the union said, after union complaints about the platform led to an ANP inspection, union representative Davison Lomba told Reuters on Friday.
