Key Industries Served

WIND ENERGY • 22,000 assets under contract globally

AEROSPACE• Rotorcraft, Fixed Wing, & Defense• (15 Years of R&D)

RAIL• Wheel Rail Interface• New Market for Sentient

Sentient Science is a trusted third party enabling life extension of rotating equipment through a digital platform, connecting operators and suppliers through asset actions that lowers the cost of energy.


What's New at Sentient Science?

1. New Product: DigitalClone Bearing available beginning of 2018 as part of our strategy to enable suppliers to create their own DigitalClone life models

2. We have Business Value Assessments (BVA) to share on how operators are reducing costs with DigitalClone Live

3. We have 2 digitalization panel sessions at the booth1. Tuesday & Wednesday at 13:00

4. We have a jazz band and party Tuesday night starting at 16:00

Wind Turbine Dynamics

Currently in Industry:

1. Wind Loads are captured on a wind farm level basis, not turbine by turbine basis

2. Used in design stage, not during operation

3. Majority of SCADA is under-utilized and not properly curated

Using DigitalClone:

• Understanding loads and reliability on an asset basis

• Replaces the needs for statistical models build out of field failure data

Validation of Loads

• Two strain gauges to measure bending moment (separated by 90o)

• One strain gauge to measure torque moment

• One accelerometer to capture hub speed
