Subsea Control Module

Subsea Control Module

SEA has developed a new low cost and short lead-time Subsea Control Module to extend the life of marginal developments and late-life fields in the oil and gas sector.

The Subsea Control Module is designed to bring a new dimension to combatting obsolescence as pressure mounts to extract more life from existing equipment, particularly in the reducing North Sea sector.

Further benefits of the SEA system include a high level of configurability while maintaining reduced complexity by using commercial off-the-shelf (COTS) hardware where available. Recent work in decommissioning has also highlighted a need for pre-abandonment monitoring systems.
