Blade Root On Site
Repair Solutions

Restore damaged blade root inserts on site, reducing downtime from months to days while avoiding transport, replacement, and factory lead times.

What we do

Repair Blades Instead Of Replacing Them.

Loose or damaged blade root bushings used to mean replacing the blade or shipping it to the factory – high logistics costs and months of downtime. We repair the blade root at the wind park instead – a world-first on-site remanufacturing solution developed with We4Ce.

A portable CNC machine removes the faulty threaded inserts and restores the blade root geometry, machining to OEM specification. New inserts using We4Ce’s patented Re-FIT bushing technology are then bonded in place. The repair covers bushings, bolts and flange surfaces – on the ground onshore, on a vessel deck offshore.

  • Downtime drops from months to days – typically 2-5 days on site
  • Up to 60% lower overall project cost – no blade transport, blade replacement or factory repairs
  • Expected lifetime similar to the original – the blade is reused, not scrapped

Why Work With Us

Four Reasons Operators Choose CNC Onsite For Blade Root Repairs.

  1. 01

    Repair Instead Of Replace

    Damaged blade root inserts are restored without replacing the blade, reducing costs and avoiding unnecessary waste.

  2. 02

    Reduced Downtime

    On site blade root repairs reduce downtime from months to days by eliminating transport, factory queues, and blade replacement lead times.

  3. 03

    Lower Total Project Costs

    Avoid blade transportation, blade replacement, factory repairs, and associated logistics, reducing overall project costs by up to 60%.

  4. 04

    Structural Integrity

    Combining CNC Onsite's precision machining technology with We4Ce's patented insert and bonding system ensures accurate positioning, reliable bonding, and long-term structural performance.
