Key Responsibilities:

Turbine Commissioning:

• Execute complete steam turbine commissioning activities (Subcritical, Supercritical & Ultra-Supercritical units).
• Conduct steam blowing of main and auxiliary steam lines, evaluate target plates, and ensure pipeline cleanliness.
• Perform lube oil flushing of turbine bearings and control systems as per NAS/ISO cleanliness standards.
• Supervise governing system logic checks, actuator stroking, and turbine rolling preparations.
• Monitor critical parameters during turbine first rolling, including axial displacement, vibration, and temperature rise.
• Support coupling alignment, turning gear operation, barring system functionality, and thermal growth observations.
  

Generator Commissioning:

• Commission the Seal Oil System, including flushing, pressure control, and interlock verification.
• Manage SCCW (Stator Coil Cooling Water) system commissioning, including pump operation, flow regulation, conductivity checks, and interlocks.
• Coordinate Air-to-CO₂ and CO₂-to-H₂ gas purging using standard OEM safety protocols.
• Handle H₂ gas filling for generator cooling, maintaining gas purity, pressure regulation, and gas leak checks.
• Oversee generator excitation system checks, rotor and stator IR, PI tests, and field flashing.
• Carry out generator synchronization, load test, and stability runs ensuring all protection systems function properly.
• Supervise cleaning and commissioning of generator gas coolers, and inspect fan operation and ducting.
• Ensure generator grounding, shaft voltage monitoring, and neutral grounding resistor commissioning (if applicable).
  

General & Interface Activities:

• Coordinate closely with control & instrumentation, electrical, and mechanical teams for logic implementation, loop checks, and equipment readiness.
• Prepare and maintain detailed commissioning protocols, test reports, and punch point closures.
• Adhere to all HSE (Health, Safety & Environment) and LOTO standards during high-energy commissioning activities.
• Interface with OEM engineers, consultants, and third-party QA/QC during test procedures and certification.
  

Technical Skills & Competencies:

• Strong expertise in supercritical turbine and generator systems.
• In-depth understanding of steam blowing techniques, thermodynamic behavior, and pipe stress management.
• Practical knowledge of oil flushing, flow dynamics, temperature management, and filter system configurations.
• Proficiency in gas handling systems – purging, filling, and maintaining gas-cooled generator safety.
• Familiarity with SCCW system operations, conductivity control, and system interlocks.
• Understanding of protection relays, synchronizing schemes, and excitation control.
• Experience with OEM standards – Siemens, MHI, GE, BHEL, Doosan, etc.
  

Educational & Professional Requirements:

• Bachelor’s / Diploma in Mechanical, Electrical, or Instrumentation Engineering.
• Minimum 12 years of field commissioning experience in turbine-generator sets of ≥210MW.
• OEM certifications or training in turbine/generator commissioning (preferred).
• Familiarity with international standards (IEC, IEEE, ANSI, ISO) and OEM procedures.
  

Soft Skills:

• Strong leadership with the ability to manage cross-functional site teams.
• Proactive problem-solving and critical decision-making under pressure.
• Excellent documentation, communication, and stakeholder coordination skills.
