Wellhead Contol Panels (WHCPs) are designed for monitoring, controlling and shutdown of Subsurface Controlled Safety Valves (SCSSV), Surface Safety Valves (SSV), Master Valves (MV), Wing Valves (WV) and other wellhead safety valves, (e.g. Choke, ESD, HIPPS) to ensure safe operation of manned and unmanned platforms.

All systems are designed and tailored to suit the individual project specifications or client/SMS developed standardised design philosophies always incorporating safety, environmental and statutory requirements.
