Introduction
The subsea control system operates the valves and chokes on subsea trees,
manifold/templates, and pipelines.
It receives and transmits the data between the surface and subsea systems.
These helps engineers to monitor the status of production by indicating
temperatures, pressures, sand detection, etc.
The location of control devices is extremely important.
Note: Careful consideration to the location of controls can result in a reduction in the
amount of piping and cabling and the number of connections required, which in turn
influences the subsea installation and retrieval tasks.
