Case study: JASO Elevator System Repair & Retrofit in Finland and in Latvia
Gridinta delivered two wind turbine access system projects focused on JASO elevator repair, retrofit, ladder alignment, and inspection works across wind farms in Finland and Latvia. Together, the projects covered 41 wind turbines and supported safer, more reliable vertical access inside operating wind turbine towers.
Project Snapshot
Project type: Wind turbine access system repair and retrofit
Locations: Finland and Latvia
Scope: JASO elevator system repair, retrofit, ladder alignment, validation inspections
Assets covered: 41 wind turbines in total
Project 1: 25 WTG in Finland
Project 2: 16 WTG in Latvia
The Challenge
Inside a wind turbine tower, safe and reliable vertical access is not a minor detail. It directly affects technician movement, maintenance efficiency, and day-to-day operational safety.
In these two projects, the scope focused on JASO elevator systems and related ladder alignment works across a large number of turbines in two different countries. That meant the work had to be delivered consistently, turbine by turbine, while maintaining the same technical standard across all units.
This kind of campaign is not only about repairing individual components. It is also about making sure access systems function correctly as a whole. Elevator performance, retrofit requirements, ladder alignment, and validation inspections all have to come together to support safe long-term use inside the tower.
Scope of Work
Gridinta supported two separate wind farm campaigns involving JASO elevator system works.
In Finland, the project covered 25 wind turbines and included JASO elevator system repair, retrofit, ladder alignment, and validation inspections.
In Latvia, the project covered 16 wind turbines and included JASO elevator system repair, retrofit, and ladder alignment works.
Across both projects, the overall scope focused on restoring and improving tower access system condition so that turbines could continue to be serviced more safely and efficiently.
How Gridinta Approached the Work
These projects required a practical, repeatable approach. When the same type of technical scope is delivered across dozens of turbines, consistency matters just as much as the repair work itself.
Gridinta approached the campaigns with a field-focused mindset: assess the condition, complete the required repair or retrofit work, align the ladder system correctly, and verify that the access setup meets the expected standard for use.
That matters in real wind farm operations, because access systems are used constantly by technicians working inside the tower. If alignment is off, components are worn, or systems are not functioning as they should, maintenance becomes slower, harder, and less safe.
By combining repair, retrofit, alignment, and validation work into structured turbine-by-turbine campaigns, Gridinta helped bring the access systems closer to the condition needed for dependable ongoing operation.
Why This Project Matters
Access systems inside wind turbines do not always get much attention in public-facing project summaries, but they are critical in the real world.
A turbine can only be maintained efficiently if technicians can move through it safely and with confidence. That is why projects like these matter. They support the day-to-day reality of wind farm maintenance, where reliability is built not only through major component work, but also through the smaller systems technicians rely on every time they enter the tower.
These Finland and Latvia campaigns also show Gridinta’s ability to deliver repeatable technical work across multiple turbines and multiple markets. Completing aligned access-system scope across 41 wind turbines requires discipline, consistency, and strong execution standards, not just one-off repair capability.
The Outcome of Gridinta’s Services
Across two separate projects in Finland and Latvia, Gridinta delivered JASO elevator system repair, retrofit, ladder alignment, and inspection-related works across 41 wind turbines in total.
The projects demonstrate Gridinta’s ability to support wind farm operators with practical tower access system works that improve reliability, support technician safety, and help keep turbines maintainable over the long term.
