EHAZOP wind power onshore station

MAR Consulting performed an Electrical Hazard and Operability (EHAZOP) analysis of an electrical onshore station for a major OEM. The station receives power generated from offshore wind turbines (North Sea). The project was in the basic design phase, entering detailed design.

Objectives of the EHAZOP

The objectives were to:

  • Evaluate the electric design with regards to safety and operability to avoid accidents and incidents;
  • Ensure that design is fit for purpose and provides sufficient reliability, availability, and maintainability;
  • Identify areas of improvement.

Scope of the EHAZOP for wind power onshore station

The E-HAZOP covered the high-power transmission and auxiliary systems. MAR Consulting further facilitated a process HAZOP for valve cooling, HVAC, climate, and sewage systems. Normal operation and other relevant modes of operation were part of the scope of work, with exception of installation, commissioning, and first energization.

Methodology for the EHAZOP for wind power onshore stations

The methodology used was based on the HAZOP methodology as per IEC 61882, adapted to electrical systems. Hence, MAR Consulting divided the electrical systems into nodes and guided the assessment using applicable guidewords and parameters. Note that the EHAZOP is not a detailed design review, nor an assessment of compliance with relevant applicable standards, but a method to identify hazard and operability issues in a structured manner.

Conclusion

These types of assessments require expert knowledge both on electrical systems but also on safety and reliability engineering. At MAR Consulting we have more than 15 years of experience working with electrical, electronic, and safety engineering. We have performed multiple of such specialized assessment (other examples: Electrical SAFOP E-HAZOP LNG project · MAR Consulting, EHAZOP offshore wind power transmission platform · MAR Consulting, Electrical SAFOP (EHAZOP) of US eLNG plant · MAR Consulting, EHAZOP of power plant concept · MAR Consulting). We have also provided related courses for engineering companies. Feel free to contact us should you require support in performing such a study.
