Brazilian state-controlled producer Petrobras has launched a tender to select contractors for work on two long-serving FPSO units that operated at the Campos basin’s Marlim field.

Issued on 8 December 2025, the call for bids covers decommissioning services together with the upgrade and reuse of the production topsides from the P-35 and P-37 units. Both platforms have been taken offline after extended service on Marlim.

Under the tender, successful contractors will refurbish the processing modules and reassemble them on the existing hulls in Brazil, enabling the units to be deployed on other projects instead of being fully dismantled.

Petrobras states that this route is aimed at optimising costs, extending the useful life of installed equipment, and strengthening domestic capability for modernising offshore production assets.

The programme will begin with P-37 under the first work package, with P-35 to follow in a later lot that combines decommissioning and reconstruction scopes. The latest tender confirms a shift away from earlier plans centred on dismantling the Marlim units and towards a reuse-focused model executed in-country.
