Subsea 7 has received a ‘major contract’ from Brazilian firm Petrobras for the development of the Búzios 8 offshore field.

The company classifies a contract as ‘major’ when the value of the deal exceeds $750m.

The field is located approximately 180kkm off the coast of Rio de Janeiro, at a water depth of 2,000m, in the pre-salt Santos basin.

Under the contract, Subsea 7 will be responsible for the engineering, procurement, fabrication, installation, and pre-commissioning of approximately 126km of rigid risers and flowlines.

It will also build 98km of flexible lines and 88km of umbilicals and associated infrastructure.

The scope of the work additionally includes the installation of floating production storage and offloading (FPSO) mooring lines and hook-up.

Subsea 7 Brazil vice-president Daniel Hiller said: “We are delighted to have been awarded this contract by Petrobras and we look forward to reinforcing our strong, collaborative relationship as we deliver Búzios 8.”

Subsea 7 plans to start project management and engineering work immediately at its offices in Rio de Janeiro and Paris.

The company will undertake pipeline fabrication at its spoolbase at Ubu, Brazil.

Subsea 7 will use one of its rigid-reeled pipelay vessels to support offshore operations, which are due to be implemented in 2024 and 2025.

Last year, Petrobras selected a joint venture (JV) of Saipem and Daewoo Shipbuilding & Marine Engineering (DSME) for the eighth FPSO unit, named P-79, in the Búzios offshore field.

The scope of the contract included the engineering, procurement, fabrication, and integration of the topsides of the FPSO unit.

Discovered in 2010, the Búzios field started production in 2018 through the P-74 FPSO.
