Subsea high-integrity pressure protection system (HIPPS) provides a safe and reliable means to unlock stranded reserves and extend the life of aging infrastructure. This presentation will provide examples of how the technology enhances the economic and operational viability of subsea tiebacks in the Gulf of Mexico by reducing costs, shortening timelines to first oil, and maximizing existing infrastructure while safely managing high-pressure reserves without costly topside modifications. With two successful installations completed and more on the way, HIPPS is set to transform future Gulf of Mexico projects by improving capital efficiency and extending field life.
