... than in the heart of the control system's subsea control module (SCM). It is no secret in industry that the SCM is one of the systems with the biggest reliability challenges. Chevron collects all the subsea reliability data in a database called Subsea Master. On reviewing the data of the SCM...

...65 Abstract The issue of improving monitoring and control of subsea completions while maintaining high reliability is critical due to accessibility and intervention costs. Hydraulic control of the downhole choke valves in multiple zones can be com- plex, and the situation is further complicated...

... and in extreme environments. Furthermore, the current high market demand requires quicker developments and enhanced reservoir recovery. Technology from the subsea communications sector is qualified and readily adapted to provide high-capacity, high-reliability communications to offshore surface and subsea...

... developed for those applications. The following principles were set early in the development process: Increased reliability: the removal of hydraulic components from the control system; a key factor in increased component reliability and system availability improvement. Elimination of control fluid...
