Role Overview
The HVDC M&E Completion Inspector is responsible for the technical assurance of converter station components. This role involves the meticulous inspection stating from Equipment receiving inspection to MC of high-power electronics, mechanical sophisticated cooling systems, and critical control/protection infrastructure, ensuring the plant is ready for highvoltage energization and long-term reliable operation.
Core Responsibilities
• Converter Valve & Electronics Inspection: Oversee the installation and mechanical
integrity of converter valves, including optical fiber connectivity, cooling pipe integrity,
and high-voltage insulation/clearance verification.
• Complex Cooling Systems: Inspect high-precision cooling systems (deionized water or
oil-based) for converter valves and transformers, ensuring leak-free performance and
proper flow calibration.
• Advanced Control & Protection (C&P): Verify the physical installation of C&P cabinets,
high-speed signal cabling, and fiber-optic backbone communication lines that are
critical to HVDC system stability.
• Auxiliary Systems: Monitor the completion of complex auxiliary power systems,
including station service transformers, harmonic filters, and neutral bus structures.
• High-Voltage Testing Support: Assist in the staging and witnessing of high-voltage
testing, including DC withstand tests, valve-level insulation testing, and operational
sequence tests.
• HVDC-Specific Quality Assurance: Manage the strict cleanliness and environmental
controls (e.g., humidity, dust) required for HVDC valve halls, ensuring all "clean room"
protocols are met during the completion phase.
• Mechanical Completion (MC) Verification
Participate in Mechanical Completion walkdowns and system inspections.
Verify all construction inspection activities are completed and documented.
Confirm punch list categorization, closure status, and readiness for pre-commissioning.
Ensure as-built documentation and quality dossiers are available and complete.
• Quality Documentation & Reporting
Complete inspection records, checklists, and test reports accurately and in a timely
manner an record in the PIMS completion system
Maintain inspection and documentation.
Track punch items, deficiencies, and corrective actions through closure.
Support preparation of Mechanical Completion Certificates (MCC).
• Commissioning Readiness: Coordinate the "Walkdown" process, ensuring every
component is compliant with the project-specific "Completion Readiness Criteria"
before the transition to the commissioning team.
Technical Requirements
• HVDC Domain Knowledge: Solid understanding of HVDC system architecture (e.g.,
VSC or LCC technology) is advantageous but not absolutely necessary.
• Optical Fiber & Shielding: Proven experience with delicate optical fiber termination and
the specific grounding/shielding requirements for HVDC noise-sensitive environments.
• Fluid Systems: Experience with industrial heat-exchanger systems, deionized water
chemistry, or large-scale cooling loops.
• Rigorous Documentation: Ability to manage high volumes of technical documentation,
including software-to-hardware mapping, signal list verification, and fiber-optic
attenuation reports.
• Safety Rigor: Comprehensive knowledge of safety protocols for HV stations, specifically
concerning stored energy hazards, high voltage switching, and specialized clearance
zones.
• Certifications: Completion Management System (CMS) and related software training
(preferably PIMS).
