RWOCS – Intervention System

The ROV Workover Control System – RWOCS is a multipurpose system, developed to simplify well access, intervention and workover operations from any type of vessel.

All the operational control equipment is fitted inside a skid and mounted under the ROV. This removes the need for extra deck spread beyond the ROV system itself, making it easy to mobilise and move the system between installations when required.

This method eliminates the need for an open-water control umbilical and a deployment frame deployed from the surface vessel. This is attractive in terms of the overall operational time required for subsea equipment deployment operations and also reduces deck spread.

The skid has two built in power packs providing hydraulic functioning lines to control and test subsea equipment via an HFL. The power pack is providing hydraulic function lines 0-690bar and each outlet line is controlled by the integrated valve packs.

The ROV Power Skid has a communication gateway enabling control and testing of subsea equipment, with electrical and communication provided by the ROV system. Electrical power is transformed subsea through a built-in subsea transformer to power up the SEM.
