In any given subsea field there is a multitude of equipment, that need to be constantly monitored. Subsea Multi-Domain Condition Monitoring can be achieved by introducing additional hydrophones, specially designed for detecting sound from rotating machinery, subsea processing equipment, structural integrity, fluid flow rate variations among others. The latest high-end sensor systems ally acoustic condition monitoring with acoustic leak detection. This works in much the same way as surface-based acoustic emission monitoring and can be used to monitor rotating machinery to check speed tracking and resonant frequencies. It can also monitor rotational equipment in subsea plant such as bearing damage, unbalanced pumps, mechanical breakdown and reduced efficiency.
