British energy firm BG Group and partners have begun a tender process for the charter of two additional Floating Production, Storage and Offloading (FPSO) vessels to be used in the full field development of the discoveries on blocks BM-S-9 and BM-S-11 in the Santos Basin, offshore Brazil.

Each of the FPSOs will have a production capacity of 150 000 barrels of oil per day (bopd) and approximately 212 million cubic feet of gas per day.

The company said that the modules are being tendered for start-up in 2014.

One FPSO will be allocated to the Guara Norte area on block BM-S-9 and the other to the southern area of the Cernambi field (formerly known as Iracema) on block BM-S-11.

Till date, with the addition of these two new modules, a total of 13 FPSOs are being procured for the two blocks, which include the Carioca and Guara areas on BM-S-9 and, on BM-S-11, the Lula (formerly known as Tupi) and Cernambi fields as well as the Iara area.

BG Group has a 25% interest in the BM-S-11 concession (Petrobras S.A. 65% and operator, Petrogal 10%) and a 30% interest in the BM-S-9 concession (Petrobras 45% and operator, Repsol 25%).
