Swiss-based marine construction specialist Allseas has picked French tubing manufacturer Vallourec to supply line pipes for Petrobras’ Búzios 10 offshore project.
This contract represents nearly 18,000 tonnes of subsea seamless premium carbon steel line pipes for the risers and flowlines. The contract includes an optional scope of almost 5,000 tonnes.
The contract also includes Vallourec’s Pipe Navigator solution, a centralised digital portal that offers instant access to up-to-date contractual documentation, data, and analysis covering every aspect of its line pipe projects.
The entire production will be carried out at our cutting-edge facility in Brazil to ensure high local content and a reduced carbon footprint.
Allseas won the contract for the design, procurement, construction, and installation of subsea infrastructure for the Búzios 10 field in February this year.
The project will be one of the largest offshore pipeline installation projects in the company’s 40-year history. Work on the project will begin in the third quarter of 2026 using the pipelay vessel Audacia. The vessel will install 111 km of rigid risers and flowlines in ultra-deep waters.
The system will link 16 wells to an FPSO via steel risers configured in a lazy wave formation. Critical components such as flex joints, pipeline end terminations, and jumpers will complete the connections.
