Subsea 7 assessing scope for three Woodside projects
Woodside Energy has contracted Subsea 7 to perform engineering studies for three new projects offshore Western Australia and Senegal.
LUXEMBOURG – Woodside Energy has contracted Subsea 7 to perform engineering studies for three new projects offshore Western Australia and Senegal.
In each case there is an option to proceed to the execute phase with an engineering, procurement, construction, and installation (EPCI) contract.
Subsea 7’s program for theJulimar gas field, 200 km (124 mi) offshore Western Australia, involves designing, procuring, installing, and commissioning of a 22-km (13.7-mi), 18-in. corrosion-resistant alloy flowline and an umbilical system.
The contractor’s Perth office is managing the program supported by other Subsea 7 global centers.
Woodside awarded the other two contracts toSubsea Integration Alliance, the partnership between Subsea 7 and OneSubsea, with integrated SPS (subsea production systems) and SURF (subsea umbilicals, risers and flowlines) project teams.
For the deepwaterSNE oil field, 100 km (62 mi) south of Dakar, Senegal, Woodside proposes up to 23 wells with more than 90 km (56 mi) of rigid pipelines incorporating Subsea 7’s Swagelining and BuBi’s pipeline technologies.
In this case the subsea integrated project team will be based in Subsea 7’s London office, with support from other Subsea 7 and OneSubsea offices.
TheScarborough gas field is 380 km (236 mi) offshore northwest Australia. Subject to a final investment decision, the scope here will encompass EPCI of subsea rigid pipelines, flexible risers, umbilicals and associated infrastructure.
Project management will be from OneSubsea’s Perth office, again supported by the partners’ other locations.
Subsea 7 will allocate reeled pipelay and heavy construction vessels from its fleet for the offshore installations which are due to take place between 2021 and 2023.
