Advances in the Control of Subsea Wells

Subsea control systems for the control of subsea trees, manifolds and processing systems are today highly reliable. Flexibility is ensured and project specific engineering is eliminated by the “configure to order approach”. The presentation will cover a brief historical overview of how control and monitoring of subsea wells has developed, including the implementation and impact of new technologies and shifts in working processes. Following the brief historical overview, the presentation will describe main features of and share experience from the implementation of the state-of-the-art series subsea controls. Specifically addressed is: -Development of “Mean Time To Failure” (MTTF) of subsea controls, discussion on reasons for the significant increase experienced -Backwards compatibility, how current products and technology can be applied to upgrade systems with 20+ years in service -Options for long distance control, 250 km and beyond -Integration of fiberoptic sensing, including Distributed Acoustic Sensing (DAS) -Hybrid electric and full electric subsea control, experience from more than 500 subsea electric actuators in service -Integration of High Integrity Pipeline Protection (HIPPS) functionality -Integration of advanced downhole completions, with many zones and high power draw The presentation is aimed to provide the audience with an overview of subsea production system control, and which features are naturally integrated to optimize the system performance.
