Brazil's economy minister has signalled the state's intention to sell off oil giant Petrobras within the next decade.
A privatisation would put shipping unit Transpetro's fleet of 27 tankers and LPG carriers up for grabs.
The whole group has a market capitalisation of $66bn.
Economy minister Paulo Guedes told an online event hosted by the International Chamber of Commerce that a number of "ambitious" divestments to private investors should move forward in the next 10 years.
