Hydraulic Control Panels

The oil & gas plant controls its oil or gas well through a wellhead control panel (usually called WHCP). Each well is always equipped with a SCSSV (Surface Controlled Sub-surface Safety Valves) or usually it is called as down hole valve (DHV) and a SSV (Surface Safety Valves) which consist of a Master Valves (MV) and Wing Valves (WV). SCSSV in most application is an on-off valve with hydraulic actuators. While SSV can be driven by hydraulic actuator or pneumatic actuator depending on the pressure rating. There is also a need to open or close SCSSV and SSV in sequence and accommodate an Emergency Shutdown signal from the systems.

WHCP systems usually consist of hydraulic reservoir, strainer, hydraulic pumps, accumulator, wellhead control module, and hydraulic lines. Any other parts except wellhead control module are housed in a basic cabinet. Each control module is built up dedicated for one well only. Therefore if there are 5 wells in a wellhead platform, then there will be 1 basic cabinet and 5 wellhead control modules.

This course provides the necessary knowledge for the participants to become familiar with the principles of oil well hydraulic control panels. Routine, emergency operation and associated features will be examined while stressing process, safety and environmental compliance and concerns. Case studies will be utilized to reinforce the material covered.

  • Agenda
  • Audience
  • Technical Information

Day 1
Wellhead valves

  • Wellhead valve types, construction and operation
  • Hydraulic panel connections to the wellhead
  • Single and multiple wellhead panels

On day 1, participants will gain a thorough understanding of the types, purpose, construction and operation of wellhead valves as found in todays oil and gas industry. Proper hydraulic panel connection for single and multiple wells will be discussed. Routine, emergency operation and associated features will be examined while stressing process, safety and environmental compliance and concerns.


Day 2
Wellhead Panel Hydraulic Systems

  • Wellhead panel hydraulic supply systems and components
  • Wellhead control instrumentation
  • Hydraulic control system

On day 2, participants will gain an understanding of wellhead hydraulic system, components and control system. Process flow and P&ID’s will be reviewed prior to covering the hydraulic control system operation for normal and emergency situations.  Process, safety and environmental compliance will be stressed.

Day 3
Hydraulic Wellhead Control Panel

  • Hydraulic switches, valves and pressure monitoring
  • Disassembly and Assembly of the Hydraulic Unit
  • Operation, maintenance and testing the Hydraulic unit
On day 3, participants will gain a thorough understanding of the system components, assembly, disassembly and testing to ensure proper operation. Testing procedures of the unit after repair will be reviewed to ensure that it is operating properly.

This course is mainly targeted to instrumentation technicians working in the field as an introduction or refresher.

The course can be applicable to technicians working in other disciplines, equipment purchasers, procurement and storage personnel, job planners and immediate supervisors.
