Before that leakage, an investigation at the external tanks of FPSO 'Cidade do Rio de Janeiro', at the Espadarte field in Brazil, revealed cracks at the hull, the Tokyo-based operator MODEC informed.

Over the weekend, 1.2 cubic meter of residual oil leaked from the unit, which was identified and recovered, the operator said.

On Monday, 26 August, in a new overflight, the presence of oil at sea was perceived, in an estimated amount of 6.6 cubic meters.

The FPSO 'Cidade do Rio de Janeiro' is located in the Campos Basin, 130 km off the coast of Brazil.
