Sentient Science is Based on Three Fundamental Capabilities
11/19/2014
We are the leader in model-based
prognostics
Model-based, multi-physics based
prognostics computational
technologies and services
Our applications help extend the
remaining useful life (RUL) of new
and existing mechanical systems
We reduce friction and improve
performance of bearings, gears,
drivetrains and mechanical systems
We are a “killer” application for the
Industrial Internet
The newest prognostics health
management (PHM) application for
condition-based maintenance (CBM)

Conclusion
• Many owners and operations are uprating their GE 1.5 to generate
more energy
• DigitalClone calculates the remaining useful life of the GE 1.5
gearbox and components when uprating to understand impacts
• There are optimal control and O&M strategies that can be
implemented for the GE 1.5 to get the highest overall ROI
• Simulation scenarios also include RUL calculations for up tower
parts replacement scenarios
