Allseas selected for subsea works for Petrobras at Ataptu-2 field off Brazil

Brazilian energy company Petrobras has contracted Allseas to deliver a rigid riser-based subsea solution for the ultra-deepwater Ataptu-II pre-salt field development approximately 230 kilometres offshore Rio de Janeiro, Brazil.

Secured through a competitive tender, the contract covers design, procurement, construction and installation of 143 kilometres of rigid risers and flowlines in water depths exceeding 2,000 metres. The subsea network will connect 18 wells to a new FPSO via steel catenary risers in a "lazy wave" configuration.
