As the number of platforms in the basin is expected to rise with increasing exploration activities, the company needs a larger area in the port to meet the current needs, it said.
Petrobras is also using ports in the Macae and Angra dos Reis cities of the Rio de Janeiro state. Both ports have reached their full capacity.
The Rio port, which will mark its 100 years of operation Tuesday, is to undergo a huge expansion in the next few years to raise its capacity by 15 to 20 percent per year.
