RIO DE JANEIRO--Brazilian state-run oil firm Petroleo Brasileiro SA said Friday that it has nominated the chief executive of mining giant Vale SA, Murilo Ferreira, as its next board chairman, as the company scrambles to deal with the fallout from a vast corruption scandal.

Mr. Ferreira's nomination will be voted on at Petrobras' next shareholders meeting April 29.

On Thursday, Petrobras said it had appointed Luciano Coutinho, head of the country's development bank, as its new chairman, but didn't make clear that the appointment would be on an interim basis. Petrobras' previous chairman was Guido Mantega, Brazil's former finance minister and a close ally of President Dilma Rousseff.

Mr. Ferreira has been the chief executive at Vale, the world's biggest iron-ore producer, since 2011, and has spent his entire career at the company. A Vale spokesperson declined to comment.

While widely respected as a chief executive, Mr. Ferreira is also known to be an ally of Ms. Rousseff and the ruling Worker's Party in Brazil. Many investors and analysts had been hoping Petrobras would name an independent chairman who could push back against what are oft-considered onerous government controls.

"As much as he is understood to be a competent person, his connection with [Ms. Rousseff] will prevent Petrobras from having a quality that everyone is looking for at this point: transparency," said Guilherme Figueiredo, a fund manager at M. Safra & Co, with $1.2 billion under management. He isn't currently investing in Petrobras. "For the minority shareholder, this is not positive, and governance remains questionable."

Mr. Ferreira steps into the role of Petrobras chairman at a crucial time for the company. It is in the midst of a widespread corruption scandal in which four former executives are accused of participating in a yearslong bribery scheme. The scandal has pummeled the company's market value, caused a shake-up of its executive ranks, and forced it to scale back an ambitious spending program.

Dozens of politicians and construction company executives have also been implicated in the scheme. Some have denied wrongdoing and others have said they are cooperating with authorities, while some have declined to comment.

The fallout from the Petrobras scandal has also contributed to a dismal overall economic picture for Brazil. Thousands of workers in the oil industry have been laid off in recent months, adding to a bleak unemployment picture here.

Mr. Ferreira's main accomplishment at Vale was slashing costs and cutting projects in the twilight of the commodity boom.

When Mr. Ferreira took over in 2011, Vale's investment budget towered at $24 billion for the year. The company had 27 "main" projects in iron ore, fertilizers, coal and base metals. Billion-dollar projects - some of which Vale later scrapped - were under way from the steppes of Argentina to the Simandou hills of West Africa.

The company also spent billions building its own super-ships to carry iron ore to China, only to have the Chinese government deny them entry. Vale has since been selling the ships off to third-party companies, though China has gradually started letting them into its ports in recent months.

Now, Vale has roughly a dozen major projects, focused mostly around its "core" business of iron ore. Its 2015 capital-expenditure budget was reduced for a fourth consecutive year to $10.2 billion.
