Lesson 1 • Vibration Analysis Fundamentals

Covers vibration measurement, frequency spectrum interpretation, and fault signatures for bearings and gears. Vibration analysis is the primary predictive tool for drivetrain health.

Lesson 2 • Oil and Lubricant Analysis

Explains particle counting, viscosity testing, and wear metal interpretation for gearbox and bearing oils. Oil analysis provides early warning of internal component degradation.

Lesson 3 • Building a Predictive Maintenance Programme

Integrates condition monitoring data into maintenance scheduling, KPI tracking, and continuous improvement cycles. Transforms raw sensor data into actionable maintenance decisions.

Lesson 4 • Structural Health Monitoring

Covers accelerometer-based tower and blade monitoring, strain gauges, and acoustic emission sensors. Structural monitoring prevents fatigue-driven failures in high-cycle components.

Lesson 1 • Post-Repair Commissioning and Verification

Applies functional testing, performance verification, and documentation closure after major repairs. Ensures turbines return to full specification before handover to operations.

Lesson 2 • Generator and Converter Replacement

Covers generator disconnection, transport, installation, and electrical recommissioning including converter parameter restoration. Minimises revenue loss during high-value component swaps.

Lesson 3 • Blade Repair and Replacement

Covers composite repair techniques, leading-edge protection application, and full blade exchange procedures. Blade repairs restore aerodynamic performance and structural integrity.

Lesson 4 • Systematic Fault Diagnosis Methodology

Applies root cause analysis, fault trees, and data-driven elimination to complex multi-system failures. Structured diagnosis reduces repeat failures and unnecessary part replacements.
