Project Overview
The FPSO Anna Nery is a floating production, storage, and offloading (FPSO) vessel operating in the Marlim field, Campos Basin, Brazil. The vessel built and converted by Yinson Production at the Cosco shipyard features a spread mooring system and a ship-shaped hull. Anna Nery has a storage capacity of 1.6 million barrels, a production capacity of 70,000 barrels of oil per day (BOPD), 142 million standard cubic feet per day (MMscf/d) of gas, and 240,000 barrels of water injection per day (BWPD).
The FPSO project in Brazil is owned by Yinson Boronia Consortium private limited. Yinson Boronia production BV holds a 63.2% share, Sumitomo Corporation owns 25%, and the Kawasaki Kisen Kaisha (K Line) holds the remaining 11.8%. The project represents a USD 5.4 billion investment. The FPSO marked the first oil production in May 2023, marking Yinson’s first asset in Brazil and a key part of the Marlim revitalization project.
Anna Nery FPSO Location
The Anna Nery FPSO is deployed in the Marlim field, located approximately 150 km off the Brazilian coast, in water depths of 927 meters. The vessel's recently updated position is on South America's East Coast.
Project Background
The FPSO Anna Nery project plays a key role in Petrobras' revitalization efforts for the Marlim and Voador fields. It extracts hydrocarbons from both post-salt and pre-salt reservoirs within these mature assets. It was originally an offshore support vessel built in 2002 by Hyundai Heavy Industries in South Korea. Later, the floating vessel underwent conversion to an FPSO, a process managed at Cosco Qidong shipyard in China, with the first steel cut occurring in October 2020.
FPSO Anna Nery is Yinson Holdings BHD's first asset in Brazil and one of its largest FPSO projects in Latin America in terms of investment and production capacity. The vessel was formerly known as FPSO Marlim 2, with Petróleo Brasileiro (Petrobras) contracting it for operations from 2023 to 2048.

The FPSO construction and conversion involved multiple stages across different locations. Yinson secured the contract for the charter, operation, and maintenance of the FPSO from Petrobras in October 2019. Before this, Yinson and Sumitomo had signed a long-term memorandum of understanding (MoU) in April 2018 to collaborate on leasing and operating FPSO and floating storage and offloading (FSO) projects. The agreement for the Anna Nery floating production unit's charter and operation was finalized in April 2020.
The first steel cutting took place at the Zhuhai Jutal Offshore Oil Services yard in October 2020. Over the next year, the FPSO underwent two dry dockings and extensive conversion work at the Changxing shipyard until Q3 2021. It then returned to the Qidong shipyard for its final phase of module lifting and integration.
The module assembly process began in December 2020, by which time 90% of the module reviews for all seven modules had been completed. Following the final integration phases, the FPSO Anna Nery achieved its first oil production in May 2023, marking a milestone in the offshore oil and gas industry in Brazil.
In October 2024, Yinson Production reduced its stake in the Yinson Boronia Consortium from 75% to 63.2% by selling an 11.8% share to 'K' Line. Sumitomo Corporation's ownership remained at 25%.

Project Timeline
Current Status of FPSO Anna Nery
As of March 2025, the FPSO Anna Nery has remained fully operational since commencing production in May 2023, consistently meeting performance expectations and supporting the revitalization efforts without any reported disruptions.
In November 2024, a special reception at the Windsor Barra Hotel celebrated the success of FPSO Anna Nery and highlighted Yinson's growing presence in Brazil. The event, attended by Malaysia’s Prime Minister Datuk Seri Anwar Ibrahim and other key officials, underscored the strong diplomatic and business ties between Malaysia and Brazil.
Yinson’s FPSO projects in Brazil, including Anna Nery, Maria Quitéria, and Atlanta, were key highlights, showcasing the company’s commitment to innovation and sustainability in offshore production. The announcement of Yinson Production’s new office in Rio de Janeiro was also made at the event.

Future Prospects of FPSO Anna Nery
The FPSO Anna Nery, along with FPSO Anita Garibaldi, is a key component of the Marlim and Voador revitalization project, which aims to extend the production of field deposits until 2048. The two FPSOs will be interconnected to 75 wells, boosting oil and gas output. FPSO Anna Nery is currently anchored at a water depth of 927 meters and linked to 32 wells.
The production capacity of the FPSO Anna Nery is expected to reach its peak in 2025. The project will play a vital role in enhancing Campos Basin’s output, which currently stands at 560,000 barrels of oil equivalent per day (boe/d). With the new systems in place, production from Marlim and Voador is set to exceed 150,000 boe/d, contributing to the basin’s projected increase to 900,000 boe/d by 2027.
Conclusion
The FPSO Anna Nery is a great asset in the Marlim and Voador revitalization project. The FPSO aims to enhance production in Campos Basin, offshore Brazil with a USD 5.4 billion investment. Integrating advanced engineering and strategic partnerships, the vessel is designed for long-term operational efficiency. Since commencing production in May 2023, it has performed as expected, contributing to Petrobras' goals of extending field production until 2048. FPSO Anna Nery will play a crucial role in sustaining energy production and supporting Brazil’s oil and gas sector in the coming decades.
