Case Studies
We help you understand and use your data assets to reveal advanced insights leading to improved decision-making, optimal asset utilization, and reduced costs. Examples of our energy solutions include:
Predictive Maintenance of Hydroelectric Generators and Turbines
We helped Sira-Kvina Kraftselskap, one of the largest hydro-power producers in Norway, build a predictive maintenance framework for finding component failures in generator and turbine systems. The team used a finite state machine (CEPtor) to extract insights from over 1400 sensors across 16 facilities, then matched those against several years of maintenance records and inspection reports to build survival (Cox), deep learning (LSTM), Bayesian, and classifier (GBM) models of system performance. Results were fed into a visualization tool (RADR) to highlight risks for the engineering team.
Results: The resulting framework was able to identify the cause of a particularly elusive generator failure that had stumped the maintenance team. Finding the source of this fault was enormously important, because this generator produces tens of millions of euros per month in electricity, making any down-time particularly costly.

Using Sensor Analytics to Predict Natural Gas Well Failure
We helped an international oil and gas exploration firm by harnessing 20 years of detailed (but very noisy) sensor readings from hundreds of wells to characterize transient well states. The client needed to predict gas well shut-ins (blockages preventing production) 4 to 6 months in advance to effectively mitigate risks.
Results: Our data science model was far more accurate than the existing baseline models. Our client now had predictions of clusters of well pads that should be prioritized for treatment or preventative maintenance. Payback for this engagement was one year.
