This presentation examines how an asset-led brownfield project delivery model improved cost, reliability, and execution performance on a producing deepwater asset. The session will highlight how a lean, multidisciplinary team integrated offshore operations, engineering, and vendor expertise to accelerate project delivery while maintaining focus on asset integrity and operational priorities. Attendees will gain insight into the processes, governance, and organizational practices that enabled end-to-end ownership of brownfield projects, reduced execution barriers, and strengthened collaboration across disciplines. The presentation will share practical lessons for operators seeking to improve the efficiency, safety, and long-term performance of mature offshore assets.
