Condition monitoring of subsea sensors. A systems of systems engineering approach

Deeper waters, remote locations and the current market reality has led to higher complexity of subsea production and processing systems oriented to increase oil recovery, reduce capital expenditures (CAPEX) and operational expenditures (OPEX), provide operational flexibility and health, safety and environment (HSE) benefits. This fact demands development of digital applications to support condition monitoring, supervision, integrated diagnosis and efficient control and operation of subsea facilities. Digital applications are highly dependent on reliable instrumentation and associated data, which might be impaired by measurements uncertainties related to sensor failures, degradation in time or unavailability. This paper explores the use of a “systems of systems engineering” approach and model based fault detection methods to develop a framework to support condition monitoring of subsea sensors to be used on digital applications.
