Operation to connect subsea well infrastructure to Brazilian FPSO about to begin

Subsea equipment installation is about to commence at Enauta’s Atlanta field offshore Brazil, connecting the wells to the floating production, storage, and offloading (FPSO) vessel which arrived at the site earlier this month.

Specialized vessel Sapura Ônix is en route to the field in the Santos Basin to carry out the installation of multiphase pumps (MPPs), umbilicals for power and data transmission, and production risers, connecting the wells’ subsea infrastructure to the FPSO.

The FPSO Atlanta arrived at the Atlanta field on May 11, as planned, and, following inspection and clearance by authorities, the vessel started its anchoring operation.

To remind, Enauta is set to replace the FPSO Petrojarl I working on the Atlanta field with the FPSO Atlanta, which it bought for Atlanta’s Full Development System (FDS) in 2022.

Chartered and operated by Malaysia’s Yinson Production, FPSO Atlanta has the capacity to process 50,000 barrels of oil per day and 140,000 barrels of water per day, and can store 1.6 million barrels of oil.

Following the naming ceremony at the Dubai Drydocks World in December 2023, the vessel left the shipyard this March, crossing oceans on its way to Brazil. The first oil is slated for August 2024, with six wells online, reaching ten wells in 2029. While the vessel’s assignment on the Brazilian field is for 15 years, it also entails a five-year optional period.

This offshore field in block BS-4 in the Santos Basin is operated by Enauta Energia, a wholly-owned subsidiary of the company, which also has a 100% interest in the asset.
