Brazilian state-controlled oil group Petrobras could join Equinor in building one of the world’s largest offshore wind farms, the Aracatu project of 4GW.

Petrobras and the Norwegian energy group are “jointly evaluating the environmental feasibility of the project”, said a statement from the Brazilian company.

Equinor had already in 2020 filed for an environmental permit to build the 4-4.7GW at Aracatu project in two phases — each consisting of 160 12-16MW turbines on monopile foundations in water depths of 15-35 metres — in the Campos Basin, 20km off the southeastern states of Rio de Janeiro and Espírito Santo.
