Petrobras has launched a last-minute tender to wrap up construction of an onshore natural gas processing unit (UPGN) to handle associated gas from a major pipeline project in the Santos basin pre-salt province.

Last month, the consortium originally hired to build the UPGN — a pairing between China’s Shandong Kerui Petroleum and local player Metodo Potencial — suspended construction work at the facility.

The UPGN is crucial to receive gas from the 355-kilometre Route 3 pipeline and process it at the Petrobras-run Comperj petrochemicals complex in Brazil’s Rio de Janeiro state.
