ANP Verdict Analyzing Operations in the Búzios Field Reinforces Companies’ Commitment, Like Petrobras, to Exploration Ethics.
The National Agency of Petroleum, Natural Gas and Biofuels (ANP) took an important step forward for the advancement of exploration in the Brazilian pre-salt by granting approval for the operation of the FPSO Almirante Tamandaré, a unit that will operate in the Búzios field in the Santos Basin, where the exploration consortium is led by Petrobras.
In this agreement, alongside the Brazilian company, there are two Chinese initiatives: CNOOC and CNODC, in addition to Pré-Sal Petróleo (PPSA).
The FPSO Almirante Tamandaré: Capacity and Technology
With an impressive production capacity of up to 225,000 barrels of oil per day and 12 million cubic meters of gas, the FPSO Almirante Tamandaré is considered the largest in Brazil to date.

Manufactured at the Chinese shipyard CMHI, the vessel arrived in Brazil in October 2024 and underwent rigorous inspections conducted by the ANP, two of which were performed at the construction shipyard and one in the offshore environment, where it is currently located.
The analysis also included a verification of all documentation involved in the operation.
The Almirante Tamandaré integrates production in the Búzios field alongside five other floating units already in operation: the FPSOs P-74, P-75, P-76, P-77, and Almirante Barroso.
The installation of this unit aims to increase production in the field, reinforcing the region’s importance for Brazil’s economy and energy security.
Commitment to Sustainability
In addition to its impressive production capacity, the FPSO Almirante Tamandaré features advanced decarbonization technologies, such as a closed flare system and heat recovery equipment.
These devices aim to optimize energy consumption, reduce greenhouse gas emissions, and contribute to the sustainability of the oil extraction process.
This innovative setup is a direct response to the environmental challenges faced by the oil and gas industry.

With historic and growing production, the Búzios field, officially marked as the largest ultra-deepwater field in the world, is considered one of Petrobras’s greatest assets.
In April 2024, the field reached the incredible milestone of 1 billion barrels of oil equivalent produced since the start of its operations in 2018.
This number highlights the strategic importance of the region for both national and international oil production.
