Brazilian state-controlled oil company Petrobras has disqualified the top two players in a tender for the charter of a flotel to carry out operations in the South American nation, throwing the entire bidding competition into uncharted territory.

Local company Aquarius Brasil BV finished on top in the tender whencommercial bids were submitted in January.

The company offered the accommodation and maintenance vessel Aquarius Brasil for a dayrate of $88,000, which would translate into a contract worth about $39.6 million.

Venus Shipping came in second with an unnamed compact semi-submersible unit, likely the CSS Venus, for a dayrate of $99,500.
