What Is GWO Certification and Why It Matters in Wind Energy

Understanding GWO: Global Wind Organisation Standards

The Global Wind Organisation (GWO) is a non-profit body established by leading wind turbine manufacturers and operators to ensure a safe work environment in the wind energy industry. GWO creates international safety and technical training standards for personnel working on wind turbines, both onshore and offshore.

Anyone entering a wind farm site—technician, inspector, or contractor—must often hold valid GWO certificates to prove they meet essential safety and technical training requirements.

 

Core GWO Training Modules for Wind Industry Workers

 

Most wind energy roles require the GWO Basic Safety Training (BST), which includes five critical modules:

  • Working at Heights
  • First Aid
  • Manual Handling
  • Fire Awareness
  • Sea Survival (for offshore roles)

In addition, GWO Basic Technical Training (BTT) covers mechanical, electrical, and hydraulic systems, while GWO Blade Repair and GWO Advanced Rescue Training (ART) are required for more specialized roles.

Why GWO Certification Is Mandatory on Wind Farm Sites

Wind turbine environments are high-risk and often remote. GWO certification ensures every technician on-site has:

  • A shared understanding of safety standards

  • Basic emergency and rescue knowledge

  • Consistent, globally recognized qualifications

  • Compliance with wind farm operator requirements (e.g., Siemens, Vestas, GE)

For companies like Gridinta, having a GWO-certified team is not just a plus—it’s often a non-negotiable for participating in tenders and international projects.

Onshore vs Offshore GWO Requirements: What’s the Difference?

Onshore technicians typically need GWO BST + BTT, while offshore personnel must also pass Sea Survival and often hold BOSIET (Basic Offshore Safety Induction and Emergency Training) for oil & gas platforms.

Roles like blade repair, welding at height, and team leadership require even more specialized GWO modules and client-specific add-ons.

GWO Certification and Career Opportunities in Wind Energy

In the growing wind industry, GWO certification unlocks access to high-paying, in-demand roles. With wind farms multiplying across Europe, Asia, and the Americas, certified professionals can find work on:

  • Offshore and onshore wind farms

  • Blade inspection and repair projects

  • Construction and commissioning teams

  • Maintenance, welding, and coating operations

GWO vs IRATA: What’s the Difference?

While GWO focuses on wind industry safety and technical standards, IRATA governs rope access techniques used across many industries, including wind.

Technicians aiming to work at height in wind energy often need both certifications:

GWO for safety and turbine-specific skills, and IRATA for vertical access and complex maneuvers.
