In a scenario of growing ships and limited waterways, state-of-the-art technology is essential to safely increase ports efficiency. That is why Brazilian Pilotage brought the most modern bridge simulator next to the maritime regulatory entities. Located a few minutes from government agencies, in the brazilian capital, our training...
