Work History
Remote Operations Engineer (Siemens Gamesa)
Engineer
10.2021 - Current
- Performed 24/7 real-time remote monitoring, control, and supervision of Gamesa, ADWEN, Siemens, and Senvion wind turbine fleets through SCADA and ROC monitoring platforms, ensuring safe and optimized turbine operation.
- Monitored WTG operational states, start/stop sequences, grid connection status, yaw/pitch behavior, and protection systems, ensuring adherence to OEM operating limits and alarm philosophies.
- Conducted alarm rationalization, fault classification, and priority-based event handling, including automatic/manual resets, remote troubleshooting, and escalation to field service teams as per ROC procedures.
- Performed trend analysis and condition assessment using SCADA time-series data (temperatures, pressures, vibration levels, rotational speeds, wind speed vs. power output) to identify early signs of component degradation.
- Executed advanced vibration monitoring and CMS/CBM analysis for gearbox stages, main bearing, generator bearings, and drivetrain, issuing technical recommendations for early intervention and failure prevention.
- Managed grid curtailment, derating, and power optimization activities, coordinating with TSOs and dispatch instructions to maintain grid stability and maximize energy yield.
- Integrated weather intelligence, wind forecasting models, and lightning detection systems into ROC operations to proactively manage turbine availability, storm shutdowns, and restart strategies.
- Implemented and optimized condition-based monitoring (CBM) and predictive maintenance strategies, coordinating with site technicians for targeted inspections, borescope analysis, lubrication checks, and component replacement.
- Led the Senvion SCADA Integration Project in collaboration with RDA Germany, including signal mapping, alarm configuration, historian setup, and data validation, enabling seamless ROC monitoring and enhanced predictive analytics.
- Supported Root Cause Failure Analysis (RCFA) by providing detailed SCADA event logs, operational trends, CMS data, and availability loss analysis to reliability and engineering teams.
- Actively monitored availability KPIs, forced outage rates, alarm response times, and turbine performance metrics, contributing to continuous improvement of ROC operational efficiency.
- Ensured strict compliance with OEM operating manuals, ROC standard operating procedures (SOPs), safety protocols, and grid code requirements across multi-OEM wind turbine platforms.
