Wellhead Control Panels
The Wellhead Control Panel is designed for monitoring, controlling, opening and closing the wellhead safety valves and other surface valves (e.g. Choke, SDV, BDV, HIPPS) to ensure safe operation of manned or unmanned sites. The Hydraulic Power Unit could be separate or integrate with the WHCP’s and is designed to provide and store (via hydraulic accumulators) different level and volume of hydraulic pressure fluid to topside and subsea control valves. Each system is designed and tailored to suit the individual project specifications or client developed standard design philosophies, always incorporating safety, environmental and statutory requirements. The systems are design for use in hazardous areas and are completely engineered, assembled and tested to the latest standards and norms in our facilities.
