TechnipFMC, in partnership with Petrobras, has advanced the qualification of some of the core technologies needed to deliver the HISEP (High Pressure Separation) process entirely subsea, several of which are proprietary and will be used in other subsea applications. These include gas separation systems and dense gas pumps which enable the injection of CO2-rich dense gas.
The Mero 3 project in Brazil’s pre-salt field will be the first to utilize Petrobras’s patented HISEP process subsea. HISEP technologies enable the capture of CO2-rich dense gases directly from the well stream, moving part of the separation process from the topside platform to the sea floor. In addition to reducing greenhouse gas emission intensity, HISEP technologies increase production capacity by debottlenecking the topside gas processing plant. These technologies are supported by Petrobras and its partners in the Libra Consortium.
The contract covers the design, engineering, manufacture, and installation of subsea equipment, including manifolds, flexible and rigid pipes, umbilicals, power distribution, as well as life of field services. The contract follows a tender process and aligns with research and development guidance established by the Brazilian National Petroleum Agency (ANP).
