Control Systems for Subsea Production (3 suppliers)
Subsea production control system is used to control and monitor subsea X-mas trees, downhole equipment and manifolds as well as subsea processing stations. There are two types of control systems such as electric and direct hydraulic control systems. An electro hydraulic control system consists of topside located computer system from which daily operation may be performed and where the safety system is interfaced. The subsea control module is the main part of subsea control systems. It contains electronics, instrumentation and hydraulics for safe and efficient operation of subsea and downhole valves. The SCM provides interfaces for communication with the topside system via the control umbilical and for downhole and subsea located instrumentation for production process monitoring and optimization.

Control Transformers (106 suppliers)
Control Transformers are principally voltage transformation devices with a wide variety of uses. Larger units may be found in electrical substations or within medium voltage switchgear to provide low voltage control power and may be 1.0 to 10 kva sized. Most control transformers are small sized. They are found throughout various control circuit and plant apparatus. Control transformers may be used to step down or step up voltage levels.

Control Umbilical (2 suppliers)
A control umbilical is used to connect topside equipment to subsea equipment. These are also used for control and operation of subsea production, subsea processing and subsea injection facilities. The control umbilical consists of hydraulic lines used for transfer of chemicals and fluids. In addition, electrical and fibre optical components used to monitor pressure, temperature, flow, vibrations are part of the construction. The type of umbilicals varies according to field requirements and the umbilicals may carry different chemical injection lines, hydraulic supply lines and electric cables and/or fiber optic lines.

Control Valves (354 suppliers)
Control valves adjust the flow rate by changing the size and shape of the flow area offered to the fluid passing through it. There are two main categories of control valve used on process plant: globe valve and rotary valves. The flow area in globe valve is dictated by the position of the valve plug relative to its seat, while the flow area in a rotary valve depends on the angular position of a disc or notched sphere within a tubular surround. A piston actuator governs the position of the flow-restricting element in both categories of valve, either directly or through a gear mechanism.
