The Parque das Conchas field in the Campos basin offshore Brazil is a phased ultradeepwater heavy-oil development tied to the Espírito Santos floating, production, storage, and offloading (FPSO) vessel, moored at a water depth of 1780 m. This paper addresses the standardized features applied to the 10,000-psi-rated subsea-system components at BC-10.


The BC-10 development is located 120 km offshore Brazil. Comprising several low-pressure reservoirs with medium- to high-viscosity oil, and in depths to 2000 m, the field’s development production was enabled by the use of subsea-boosting-and-separation caisson electrical submersible pumps (ESPs), each powered up to 1,500 hp through a high-voltage three-phase alternating-current transmission system, with pressure boosting of up to 2,300 psi from each pump. The development was divided into three distinct phases that tied five different reservoir structures to the host by use of subsea-tieback field architecture. The three phases are detailed in the complete paper.
