Itaqui, strategically located on Brazil 's northeast coast and closer to Europe and the United States than the country's southern ports, moved 15.7 million tonnes of cargo in 2012.
By 2030, it hopes to handle 150 million tonnes per year, said Luiz Carlos Fossati, president of the Maranhense Port Administration Co (Emap), in an interview.
The company plans to invest 1.4 billion reais in Itaqui by 2016, he said.
Brazil 's National Transport Confederation has said the country's ports are among the slowest and most costly in the world, due partly to lack of investment.
President Dilma Rousseff announced late last year a $26 billion plan to modernize the country's public ports. Brazil, an agricultural superpower, has had trouble making timely export deliveries of this season's record soybean crop. (Reuters)
