Solving a major challenge in the wind industry

30%

Over 30% of blade maintenance costs come from surface defects

1 in 3

1 in 3 repairs must be redone due to inaccurate inspections

ā‚¬ 2.000

The maintenance costs for wind turbine blades can reach ā‚¬2,000 for each megawatt of energy the turbine can produce.

Traditional inspection methods fall short

Visual inspections lack reliability

Visual inspections are the most commonly used method for assessing blade coatings, but they rely heavily on the inspectorā€™s experience and subjective judgment. This means defects can be easily overlooked, especially when they are beneath the surface. Furthermore, environmental conditions such as lighting or weather can impact visibility, leading to inconsistent results.

Ultrasound and eddy currents measure only a single layer

Traditional non-destructive testing methods, such as ultrasound and eddy current testing, are limited in their ability to analyze multilayer coatings. These techniques can only measure the total thickness of a single layer at a time, making it impossible to evaluate individual layers within a coating system. As a result, critical defectsā€”such as poor adhesion between layers or irregular thickness distributionā€”may go undetected.

With Notus, you get full control

  • Precise measurement of each coating layer thickness
  • Evaluation of paint adhesion to the blade surface
  • Detection of invisible defects like bubbles, pores, and orange peel
  • Identification of voids and gaps in structural adhesive joints

Watch Notus in action!

Traditional inspection methods struggle to detect issues beneath the surface, but Notus changes the game. Using terahertz waves, Notus goes beyond visual inspections and single-layer measurements, providing a complete, non-destructive analysis of each coating layer on wind turbine blades.

Running 24/7 since its installation, it provides unprecedented data on the painting process, enabling a 15% cost reduction through material, energy, and defect minimizationā€”delivering both economic and environmental benefits.
