During my shift at a 2 MW turbine farm, I was scheduled for the monthly blade pitch system check.

My task was to verify that the pitch actuators, sensors, and control wiring were operating within manufacturer tolerances.

I first accessed the turbine via the service lift, then used the manufacturer’s diagnostic software to read actuator positions while manually cycling the blades through their full range. I inspected hydraulic lines for leaks, checked sensor wiring for corrosion, and recorded all readings in the maintenance log. Any deviation triggered a deeper inspection of the actuator motor and a recalibration using the OEM toolkit.

The inspection confirmed all parameters were within spec, preventing potential over‑speed events. The log entry satisfied compliance audits and contributed to a 0% downtime record for that month.

While on call for a 3 MW turbine, the SCADA system flagged a generator overheating fault (code G‑HOV).

I needed to identify the root cause, mitigate the risk, and restore normal operation while adhering to safety and environmental regulations.

I first initiated an emergency shutdown using the turbine’s remote kill switch and verified lockout/tagout on the generator circuit. I then inspected cooling fan operation, checked coolant flow rates, and measured bearing temperatures with infrared thermography. The fan motor showed reduced amperage, indicating a bearing seizure. I replaced the fan motor, re‑filled coolant, and performed a controlled restart while monitoring temperature trends.

Generator temperatures returned to normal within 10 minutes, the fault cleared, and the turbine resumed power production without incident. The incident report was filed, and the corrective action was added to the preventive maintenance schedule.

Before beginning a scheduled maintenance window on a 2.5 MW turbine, I was responsible for ensuring all work met OSHA and IEC 61400‑2 requirements.

My task was to coordinate the crew, verify permits, and conduct a safety briefing that covered both OSHA and IEC standards.

I reviewed the work permit to confirm lockout/tagout, confined space entry, and fall protection requirements. I then led a toolbox talk that highlighted specific IEC 61400‑2 clauses on electrical isolation, wind speed limits for work, and emergency evacuation routes. I ensured each technician wore a harness, inspected rescue equipment, and documented the briefing in the safety log. Finally, I performed a pre‑task inspection of all tools and verified that the turbine was in a safe wind condition (<10 m/s).

The maintenance was completed without any incidents, passed the internal audit, and the crew received positive feedback for adherence to safety protocols. The turbine returned to service on schedule, and the compliance documentation was accepted by the regulatory auditor.

During a routine gearbox inspection, I noticed a colleague attempting to start the turbine without completing the lockout/tagout steps.

I needed to stop the unsafe action, address the safety breach, and ensure the team understood the importance of the procedure.

I immediately called out, "Stop, lockout/tagout first," and physically placed the lockout device on the power circuit. I then escorted the coworker to the safety officer, explained the violation, and we reviewed the lockout/tagout checklist together. After the turbine was properly isolated, we resumed work, and I led a brief debrief to reinforce the policy with the entire crew.

The turbine remained safely isolated, the coworker acknowledged the mistake, and the safety officer documented the incident as a near‑miss. The debrief helped prevent future breaches, and the crew completed the inspection without further safety issues.

A 1.5 MW turbine went offline due to an unexpected vibration alarm during peak production hours.

I was tasked with coordinating the electrical, mechanical, and control engineers to diagnose and fix the issue within a tight timeframe.

I organized a quick huddle, assigned roles—mechanical team to inspect the rotor bearings, electrical team to check the drive‑train wiring, and control engineers to review SCADA logs. I facilitated real‑time updates via a shared tablet, ensured everyone followed lockout/tagout, and documented findings. The vibration was traced to a misaligned bearing, which the mechanical team replaced while the electrical team verified sensor integrity.

The turbine was back online in 3 hours, restoring 1.5 MW of generation. The collaborative approach was praised by management, and the incident report highlighted the effective cross‑functional communication.

Mid‑climb on a 2 MW turbine, the wind speed rose from 8 m/s to 18 m/s, exceeding our safe working limit.

I needed to ensure the safety of myself and the crew while minimizing downtime.

I immediately signaled the crew to halt the ascent, secured my harness, and initiated the emergency descent protocol. I communicated the wind change to the control room, which logged the event and halted turbine operation. Once on the ground, we performed a post‑event safety check, documented the wind data, and rescheduled the task for a later, calmer window.

No injuries occurred, and the turbine remained protected from potential wind‑induced hazards. The incident was logged, and the team received commendation for adhering to the wind‑speed safety threshold.
