Petrobras has contracted Subsea 7 to provide multiple services to develop the Mero-3 field, 200 km off the southern coast of the state of Rio de Janeiro. This field lies in water depths of 2.2 km below the salt layer of rock, within the seabed, that covers much of the region.
Subsea 7’s contract scope includes engineering, fabrication, installation and precommissioning of subsea lines and equipment. The subsea spread will be linked to a floating production storage and offloading (FPSO) vessel on the Mero-3 project.
Subsea 7 will install 80 km of rigid risers and flowlines for the steel lazy wave production system, 60 km of flexible service lines and 50 km of umbilicals and associated infrastructure.
When the FPSO arrives in 2024, Subsea 7 will install the mooring lines and carry out the hook-up work. Project management and engineering will commence immediately at Subsea 7’s offices in Rio de Janeiro and Paris, France.
Fabrication of the pipelines will be conducted at Subsea 7’s spool base at Ubu in the state of Vitória, Brazil.
Subsea 7 said offshore operations are scheduled to be executed in 2023 and 2024, using its fleet of reeled, rigid pipe-lay vessels.
“This contract builds on our strong, collaborative relationship with Petrobras and track record of executing major engineering, procurement, installation and commissioning projects globally,” said Subsea 7 vice president for Brazil Marcelo Xavier. “We look forward to working closely with Petrobras to successfully deliver this project.”
Subsea 7 defines a very large contract as being between US$500M and US$750M.
In the UK, Reach Subsea has been awarded two call-off contracts under one of its frame agreements for execution in 2021. This represents about 45 vessel days and will be performed by the Olympic Delta spread, said Reach.
The projects involve inspection, maintenance, repair and decommissioning work in the UK, with immediate start-up of planning and engineering.
