(Petrobras, 27.May.2024) — The platform ship Marechal Duque de Caxias arrived in Brazil on 27 May 2024, from China, heading for the Mero field in the pre-salt Santos Basin. The platform of the FPSO type (floating production, storage, and transfer unit) can produce up to 180,000 barrels of oil and compress up to 12 million cubic meters of gas, all daily. The unit will start operating in the second half of this year.

The FPSO left the shipyard in Yantai, China, in February this year and then made a stop in Mauritius, Africa, to change crew and move cargo. In Brazil, the unit will be installed in the Mero field, where it will be connected to the wells and subsea equipment. Before starting production, the FPSO will undergo legal procedures and final tests of the production equipment.

The Marechal Duque de Caxias FPSO, chartered from MISC, will increase the field’s installed production capacity to 590,000 barrels of oil daily. This production system provides for the interconnection 15 wells to the unit, 8 oil producers, and 7 water and gas injectors through a subsea infrastructure comprising 80 km of rigid production and injection pipelines, 47 km of flexible service pipelines, and 44 km of control umbilicals.

The FPSO is part of the 3rd Mero definitive production system, in which Petrobras intends to implement HISEP technology from 2028, which will separate the oil and gas at the bottom of the ocean, from where it will reinject the CO2-rich gas in a pioneering way. The FPSO Marechal Duque de Caxias has other technologies to reduce emissions, such as CCUS (Carbon Capture, Utilization, and Storage), where CO2-rich gas is reinjected into the reservoir.

Petrobras is the operator of the unitized Mero field, conducted in a consortium, whose holdings are as follows: Petrobras (38.6%), Shell Brasil (19.3%), TotalEnergies (19.3%), CNOOC (9.65%), CNPC (9.65%) and Pré-Sal Petróleo S.A (PPSA) (3.5%) as the Federal government’s representative in the non-contracted area.
