TÜV SÜD National Engineering Laboratory has launched its data analytics service to help oil and gas operators minimise flowmeter downtime and maintenance.
The total cost of calibrating an offshore flowmeter is estimated to cost $50,000 (€41,000).
The new data analytics service will enable operators to move away from a time-based calibration approach to condition-based calibration, by using statistical modelling techniques to predict meter performance based on live and historical data.
In addition, diagnostics information can be used to understand what may be negatively impacting a meter by analysing hidden patterns to identify specific fault conditions.
This can include incorrect installation, instrument damage, particle deposition, the presence of an unexpected second fluid phase, and upstream or downstream flow disturbance.
Gordon Lindsay, head of the digital R&D group at TÜV SÜD National Engineering Laboratory, said: “Thanks to advances in technology and increased connectivity through the Internet of Things, vast amounts of data exist, but only a fraction of its potential benefit is realised. Our new Data Analytics service uses data in real-time to detect when a meter is not performing to specification and identify the cause of this failure. This means that end-users can avoid shutting down production to remove a device from the pipeline before a solution to a fault can be found. Recalibrations are both costly and labour intensive, so proactively determining the optimal calibration date delivers increased measurement confidence, reduced downtime and cost savings.”
