The objective of this project is to assess and advance the state of technology concerning subsea all-electric High-Integrity Pressure Protection Systems (HIPPS); a technology enabling extraction from high pressure fields and expansion of existing low-pressure subsea production networks. An all-electric fail-safe HIPPS will help ensure the integrity and safety of any downstream subsea equipment not rated for the wellhead shut-in pressure. This research addresses the unique requirements associated with safety, integrity, and reliability of practical subsea facilities. Successful commercialization and utilization of an all-electric HIPPS system will result in an added barrier to avoid environmental problems downstream of the system.
