Product Overview

Summary: This Safe Operating Procedure sets out a structured approach for monitoring the health and integrity of onshore wind turbines, with a strong focus on worker safety and asset reliability. It brings together condition monitoring, inspection routines and WHS controls to help Australian operators detect faults early, prevent catastrophic failures and protect technicians working at height and around high‑energy systems.

Onshore wind turbines operate in harsh, variable conditions and combine high‑voltage electrical systems, rotating machinery and work at height – all of which present significant safety and reliability risks if not tightly controlled. This SOP provides a clear, repeatable framework for health monitoring activities, integrating condition monitoring data, scheduled inspections and field verification with robust WHS procedures suitable for Australian wind farms. It defines how to plan, execute and document monitoring tasks so that emerging defects are identified early, technicians are protected, and turbines remain safe to operate over their full lifecycle.

The procedure addresses the full monitoring workflow: from risk assessment and permit-to-work requirements, through lock out–tag out (LOTO), access and egress to the turbine, safe use of diagnostic tools and sensors, and structured interpretation and escalation of alarms and condition data (vibration, temperature, oil analysis, SCADA trends and visual inspections). By standardising these steps, the SOP helps operators comply with WHS legislation, reduce unplanned outages, and minimise the likelihood of blade failures, gearbox breakdowns, electrical fires or dropped objects. It also provides a defensible audit trail demonstrating due diligence in managing high‑risk plant, supporting both regulatory compliance and insurer expectations.

Key Benefits

• Ensure safe planning and execution of turbine health monitoring tasks, including work at height and within confined nacelle spaces.
• Reduce the risk of catastrophic mechanical or electrical failures through systematic condition monitoring and early fault detection.
• Standardise health monitoring practices across sites, contractors and shifts to improve consistency, data quality and WHS compliance.
• Demonstrate due diligence under Australian WHS law with clear records of inspections, risk controls and maintenance decisions.
• Optimise turbine availability and lifecycle costs by linking health monitoring findings to maintenance planning and repair priorities.
