About our Intervention Workover Control Systems

A Workover Control System comprises a control room section within a positive pressure-certified container, as well as an HPU section suitable for use in hazardous areas.
Hydraulic power for the subsea operations is generated by the HPU section, and is delivered together with electrical power and signals through umbilicals connected to the subsea equipment.
The Master Control Station provides overall control and monitoring of the subsea systems. The Control Station interfaces with the HPU to monitor its status during installation and work-over activities.
Frames units are designed to comply with international standards such as:

  • ISO 13628-Design and operation of subsea production systems

  • IEC61508 and IEC61511-Safety systems

  • DNV 2.7.1 -Design standard for offshore containers
