SEA Global provided senior-level engineering and management support throughout the feasibility, FEED, and Detailed Design phases, establishing technical direction for subsea scopes and contributing to execution strategies, cost estimates, and schedules for Phase 3 and 4 of the project.
The seconded team delivered specialised support in the design and installation of subsea pipelines and production systems, alongside providing quality assurance and procurement oversight for subsea materials and equipment. The work also involved proactive interface management to ensure a seamless transition from design to fabrication and construction phases, close collaboration across Downstream, Platform, and Installation teams for integrated solutions, and strategic involvement in the StablePIPE initiative utilizing the O-Tube testing facility. During the Operations Phase, the scope extends to survey planning, asset integrity assessments, providing cyclonic response tools, and managing asset information via a geospatial digital twin developed for the Wheatstone subsea assets and export trunkline.
