Wellhead Control Panel (WHCP)

The WHCP is an emergency shutdown system, installed near the wellhead, which is an automatic control system for SCSSV, MV and WV valves and can achieve remote emergency shutdown with functions such as high and low pressure protection of the production pipeline, anti-fire and H2S gas leakage shutdown.

Description

Wellhead control panel (WHCP), also known as wellhead/downhole safety control system, can be divided into single wellhead control and multiple wellhead control basins according to the number of controlled wellheads. The wellhead safety control system (WHCP) is mainly used for controlling the surface and underground safety of oil and gas wells, providing safety protection for unmanned oil and gas wells in the field, effectively preventing or reducing oil and gas well accidents. High pressure, high, and high-risk oil (gas) wells that are widely used in various outdoor environments such as land, ocean platforms, artificial islands, and deserts. Each has functions such as emergency shutdown, transportation shutdown, industrial shutdown, and fire shutdown. The power can be provided by meters, natural gas, nitrogen, solar energy, AC power, and DC power.
