BRASILIA, April 23 (Reuters) - Brazilian President Luiz

Inacio Lula da Silva said on Tuesday that the situation of the

state-run oil giant Petrobras is "calm" and the firm

has never been through a crisis.

"I don't see a problem at Petrobras, the fact that there is

a disagreement, a misunderstanding is part of the human

relationship," he told journalists at the Planalto Palace.

The firm's CEO is set to remain at the helm after weeks

under fire by parts of Lula's coalition, which prompted intense

speculation about his departure.
