Wellhead Control Systems And Solutions

HR has massive project experience in the design, manufacturing, and commisionning of the wellhead safety control system (WHCP), which can be single-well controlling, multi-well controlling, or solar powered. The applicable scenarios can be onshore, offshore, desert areas, or artificial islands.

As the leader and innovator in WHCP, HR strickly follows the standards of system design, cutomers' speficiations, and fabrication to assure the reliability, maintainability, and feasibility. The control of WHCP varies from pneumatic/hydraulic to PLC-based.

Multi wellhead control panel

Based on the characteristic of centralized control of multiple oil/gas wells on the ocean, HR has developed a multi-well wellhead safety control system, which contains multiple wellhead control modules. Each control module controls one well independently without interference, which facilitates maintenance and replacement.

The control system can be designed according to customer requirements as pneumatic-hydraulic, electric-pneumatic, electric-hydraulic systems with remote control interfaces.

Power source: manual hydraulic pump, electric hydraulic pump, pneumatic hydraulic pump.

Control objects: surface safety valve and subsurface safety valve, etc.

Applicable working conditions: oil and gas wellheads on offshore platforms.

Functions And Features

1. The system consists of a shared HPU module and simplex wellhead control modules. The overall system can control up to 30+ wells.

2. The system is suitable for use in offshore environments, and all components are made of materials superior to 316 SS.

3. The explosion-proof rating can reach Ex d IIB T4 and above, suitable for Zone 1, Gas Group IIB, and Temperature Class T4 and

4. The protection level can reach IP66.

5. It has functions such as local shutdown, remote shutdown, ESD manual station shutdown, fusible plug shutdown, and high and low pressure pilot valve shutdown.

Wellhead control panel

For wellheads that require high reliability and programmable logic control, HR has developed the PLC-based wellhead control system. The system is designed with advanced fault-tolerant, fail-safe programmable logic controllers, internationally certified safety I/O modules, simplex/redundant configurations, and communication modules for intelligent control of the wellhead.

Power sources: manual hydraulic pumps and electric hydraulic pumps.

Control objects: surface safety valves and subsurface safety valves.

Applicable working conditions: wellheads that require high reliability and programmable logic control.

Functions And Features

1. The hydraulic pump is driven by a 380V AC motor.

2. Suitable for single-well and multi-well control.

3. Controlled by solenoid valves, can be operated through panel buttons or touch screen.

4. Explosion-proof level can reach Ex d IIB T4 and above, suitable for Zone 1, Gas Group IIB, and Temperature Class T4 and above.

5. Protection level can reach IP66.

6. Optional redundant PLC control module.

7. System safety level can reach SIL3.
