The third largest global energy company and headquartered in the UK, BP is operator of such major offshore UK producers as the Foinaven and Forties fields.
Instrument & Controls engineers design, install, manage, and maintain equipment which is used to monitor and control engineering systems, machinery and processes. Instrumentation is vital in measuring and controlling parameters such as pressure, flow, temperature, current, and voltage by gathering information from the field and then changing its parameters via a control loop. Instrument & Controls engineers therefore aim to improve productivity, stability, safety, continuity and optimization through measurement, automation and control processes.
