Porto of Açu, Industrial port complex in São João da Barra, Brazil

The Port of Açu is a private industrial port complex in São João da Barra, Rio de Janeiro, with two terminals, T1 onshore and T2 offshore, and 17 km of quay. T1 is reached by a 2.9 km access bridge on 662 piles, 27.5 m wide, carrying ore conveyors. A long narrow concrete pier with low white and gray edges and short bollards serves the berths, where ore carriers and tankers moor alongside.

Launched officially in late 2006 with businessman Eike Batista and Rio governor Rosinha Garotinho present, construction began in October 2007. The EBX group's crisis led to the sale of its logistics arm LLX to the American group EIG in August 2013, which took 53% control and renamed it Prumo. Operations started in October 2014, and the T-OIL petroleum terminal began operating in August 2016.

The port's name comes from the Açu district of São João da Barra where it stands, and locals know the complex as Superporto do Açu, the name used when Eike Batista launched the project in 2006. Its 90 km² rear area covers about 20% of the municipality's territory, an area the size of the city of Vitória in Espírito Santo.

The port is equipped with modern infrastructure to handle large vessels, with berths for different cargo types and appropriate storage areas. Visitors should note that this is an active industrial facility and access may be restricted in certain areas.

The port can accommodate ships in waters of exceptional depth, making it particularly valuable for transporting large quantities of crude oil. This capability allows the facility to handle a major portion of Brazil's oil exports.
