Ireland produces around 35% of its electricity from wind, with the bulk of the trade based on the west coast (Mayo, Kerry, Donegal) and offshore wind growing fast in the Irish Sea. A wind turbine technician climbs 80-150 metres routinely, often in worse weather than the rest of the country tolerates. The training stack is intense - here is how it fits together.
The certifications stack
- GWO Basic Safety Training (BST) - 5 modules: Working at Heights, First Aid, Manual Handling, Fire Awareness, Sea Survival (offshore)
- GWO Basic Technical Training (BTT) - electrical, mechanical, hydraulic, installation
- Advanced Rescue Training - hub, nacelle, blade rescue scenarios
- High Voltage / Low Voltage - depending on role
- First Aid + AED - 2-day approved
- Working at Heights Course - the SHWW Act and Irish-specific duties
GWO is the international wind industry standard. The Working at Heights Course adds the Irish legal layer that GWO does not specifically cover.
Tower access systems
Modern Irish wind farms (Tilbury Green, Galway Wind Park, Beal Hill, etc.) use:
- Internal tower service lift - takes 2-4 technicians plus tools to nacelle
- Backup ladder with rigid rail fall arrest (Type D EN 795)
- External hub crane for blade and component work
- Blade access platforms - suspended from hub
Each system has a documented inspection cycle, daily pre-use checks and operator-specific induction.
Weather and the wind farm shift
Wind technicians work to wind speed limits at hub height, which can differ wildly from ground level:
- Wind over 18 m/s at hub - stop external work
- Wind over 12 m/s during external climb / blade walk - stop
- Lightning within 30 minutes - evacuate
- Sea state above operator threshold - no offshore transfer
Rescue at height in wind
Casualty in nacelle or hub means a 60-100m vertical rescue. Equipment carried on every shift:
- Rescue descender rated for the tower height
- Casualty stretcher and immobilisation kit
- Trauma first aid + AED
- Clear comms with operator control room and emergency services
- Helicopter access plan for offshore
Suspension trauma
Wind technicians spend more time hanging in harness than almost any other trade. Suspension trauma protocols are drilled relentlessly:
- 15-20 minute window to relieve suspension
- Trauma straps (Petzl Bandelet, similar) clipped to harness for self-rescue
- Slow descent and recovery position - never lay flat immediately
- Medical follow-up mandatory after any suspension over 10 minutes
The Irish-specific training piece
The Working at Heights Course online covers the SHWW Act and the EU Directive 2001/45/EC duties. The course is recognised by all major Irish wind operators and contractors as evidence of the legal compliance layer that sits underneath GWO. 45 minutes online, instant Working at Heights Certificate.
Career path notes
Entry into Irish wind typically goes: trade qualification (electrical, mechanical) -> Working at Heights Course -> GWO BST -> employer apprenticeship -> hub work after 1-2 years. The 45-minute online cert is an early checkbox that lets you apply for graduate placements.
FAQs
Is the offshore wind sector developing in Ireland?
Yes. Codling, Dublin Array and several other offshore projects in advanced planning will significantly expand the skilled-technician demand 2026-2030.
Can someone with no construction background enter wind?
Yes. Many GWO BST candidates come from electrical, mechanical or even ex-military backgrounds. The Working at Heights Course is a good first step before committing to the full GWO investment.
How long does GWO BST take?
5 days, classroom and practical, refreshed every 2 years.
