Petrobras has awarded Subsea 7 a ‘very large’ contract to deliver subsea equipment for the Mero-3 field development offshore Brazil.

Subsea 7 defines a contract as ‘very large’ when its worth is between $500m and $750m.

Under the contract, Subsea 7 will engineer, fabricate, install and pre-commission 80km of rigid risers and flowlines for the steel lazy wave production system.

The contract scope also includes 60km of flexible service lines, 50km of umbilicals and associated infrastructure, as well as the installation of FPSO mooring lines and hook-up.

The company plans to immediately start project management and engineering work at its offices in Rio de Janeiro, Brazil, and Paris, France.

Subsea 7 Brazil vice-president Marcelo Xavier said: “This contract builds on our strong, collaborative relationship with Petrobras and tracks record of executing major EPCI projects globally. Subsea 7 looks forward to working closely with Petrobras to successfully deliver the project.”

The firm will fabricate the pipelines at its spool base at Ubu in the state of Vitória, Brazil. It will undertake offshore operations in 2023 and 2024.

Situated approximately 180km offshore Rio de Janeiro in the prolific pre-salt area of the Santos Basin, the Mero ultra-deepwater oilfield is being developed in four phases.

It is under a production sharing agreement to Libra consortium involving Brazilian state-owned oil company Petrobras with a 40% stake.

The Mero-3 field is planned to be developed through the FPSO Marechal Duque de Caxias, which will have 180,000 barrels per day (bpd) of oil and 12 million cubic metres of (MMcm) gas a day processing capacity.

The development involves eight production and seven water and gas injection wells.

Libra Consortium made the investment decision on the Mero-3 FPSO vessel in 2020. The FPSO is planned to enter service by 2024.
