Two subsea service providers are battling for a Petrobras contract encompassing critical equipment to assist in development at the giant Buzios pre-salt field in the prolific Santos basin offshore Brazil.

Well-informed industry sources told Upstream that Norway’s Aker Solutions and OneSubsea, a Schlumberger-owned subsidiary, have submitted the best offers in a tender to supply subsea trees and associated gear to serve the Buzios-9 project.

Brazilian oil giant Petrobras asked suppliers for a total of 15 subsea trees, two pipeline end manifolds (PLEM), two electro-hydraulic distribution units (UDEH), as well as connectors, spare parts and support to provide installation, intervention, preservation and maintenance services.
