Swiss-based marine construction specialist Allseas has won a contract for the design, procurement, construction, and installation of subsea infrastructure for the Búzios-10 pre-salt field, located some 180 kilometres off the coast of Rio de Janeiro.
According to Allseas, the project, awarded by Petrobras following a competitive tender, 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.
Allseas opened a new project management and engineering office in Rio de Janeiro to support this contract. It will also serve as the company’s strategic hub throughout the project. The Swiss firm also committed to at least 40% local labour content which will generate 2,000 jobs.
The Búzios-10 project also marks Allseas’ return to the Brazilian offshore construction market, following successful campaigns installing export pipelines for Petrobras’ Rota 1, Rota 2, and Rota 3 pre-salt developments.
