Wellhead control panel energy storage device

How does a Wellhead Control Panel (WHCP) work?

A Wellhead Control Panel (WHCP) works by utilizing a hydraulic pump to build up a hydraulic header (high or medium pressure). The Subsurface Safety Valve (SSSV) operates at high pressure, while the Surface Safety Valve (SSV) operates at medium pressure.

How does a Wellhead Control System work?

Wellhead control systems are designed to be ‘fail-safe’. They receive input signals from various gauges, including pressure, temperature, and flow gauges in the wellhead, and are programmed and controlled by PLC or SCADA systems.

What is a wellhead valve panel?

These panels are designed to control a single well and associated valves. These panels are primarily used in onshore environments. Pneumatic/ Hydraulic energy is used to actuate other Wellhead valves. These panels are designed to control multiple wells and associated valves. These panels are mostly used in offshore environments.

What is a single wellhead control panel?

The categorization of single wellhead control panels is based on the type of actuation resource they utilize: Manual Control System: Allows for direct, hand-operated control over the wellhead valves. Electrical Control System: Utilizes electrical signals to actuate the wellhead valves for precise control.

How are offshore platform wellhead control systems grouped?

The wellhead control systems for offshore platforms are grouped onto one or more panels. On land wells, a separate wellhead control system is used for each well working under high pressure. Hence, WHCP is a collection of diverse control systems that enable the controlled execution of plans and emergency shutdowns.

What is a PLC based wellhead control system?

Whenever there is a requirement for high reliability and high availability, PLC-based Wellhead control systems are used. WHCPs are also known as Shutdown Panels (SDP), Emergency Shutdown Systems (ESD), and Hydraulic Safety Shutdown System (HSSS). These are failsafe shutdown systems that have pneumatic/hydraulic/electric components.
