Parque das Conchas, also called BC-10, is in the north of the Campos Basin, offshore Espirito Santo state, Brazil. The project consists of five fields: Ostra, Argonauta B-West, Abalone, Argonauta O-North and Nautilus. Parque das Conchas (BC-10) is a major milestone in the development and commercialisation of Brazil’s deep-water oil. The project comprises three fields which have been developed with subsea wells and manifolds. All connected to a centrally located floating production, storage and offloading (FPSO) vessel, the Espírito Santo, moored in around 1,800m of water. The development is the first of its kind based fully on subsea oil and gas separation and subsea pumping. The system uses 1,500-horsepower underwater pumps – each equivalent to a Formula One engine - to drive oil and a small quantity of gas to the surface.
