Wellhead control panel (W.H.C.P)
wellhead control panel
– Control systems for the upstream production of oil and gas from wellhead control/shutdown panels to production Control and safety on offshore and onshore.
– Wellhead Control Panels and Systems monitor vital process safety parameters of a wellhead platform and provide safe and sequential start-up and shutdown of production wells as per design SAFE charts.
– Use the Hydraulic high pressure for sub surface safety valve (sssv)/Down Hole valve/SCSSV.
– Use the Hydraulic medium pressure supply for master valve/surface safety valve (ssv).
– Use the Hydraulic medium pressure supply for Wing valve.
– Use the Hydraulic medium pressure supply for Annulus valve.
– All device suitable to exposed to direct sun light and placed in a saline and corrosive atmosphere, high Air humidity, high Air temperature, sulphurous , dust area.
– All parts in contact with hydraulic oil are made stainless steel.
– Fail safe operation.
– Wellhead shutdown systems are supplied with integrated or separate stand-alone or skid mounted hydraulic power units (HPUs) complete with redundant hydraulic pumps, accumulators and reservoirs etc.
– Select devices according to vendor of customer.
– Suitable for Safe/Explosion area.
– Electrical control (Relay or PLC base).
– Logic operation may be:
Pneumatic (instrument air).
Pneumatic (gas).
Electrical (24V DC).
Hydraulic generated within the panel.
