Demo North Sea Wind — Coating Passport

Annual drone inspection of an 80 m offshore blade. Leading-edge erosion at 32% of LEP coating loss correlates to 1.5-2.5% AEP penalty per DNV-RP-0573. Shear-web delamination flagged for borescope follow-up. Trailing-edge crack within propagation tolerance.

Findings detail

erosion

confidence 93%312 framesimg-quality 88%severe

Leading-edge erosion estimated 32% of LEP (leading-edge-protection) coating loss over 20 m outer span. AEP loss correlation: 1.5-2.5% per DNV-RP-0573 erosion-impact curves.

Location: Leading edge, 50-70 m from root (0, 0, 60)

Recommended action: Plan LEP reapplication at next planned maintenance window. AEP loss correction adequate to scope mid-cycle repair vs end-of-cycle.

delamination

confidence 81%47 framesimg-quality 78%moderate

Localized bond-line delamination, ~0.6 m² at shear web. Structural significance moderate per DNV-RP-0573.

Location: Shear web bond line at 35 m station (1.4, 0, 35)

Recommended action: Internal inspection (borescope) at next campaign; consider thermography-confirmation pass.

crack

confidence 76%23 framesimg-quality 71%minor

Surface crack ~45 mm at trailing edge, tip section. Below 200 mm propagation threshold.

Location: Trailing edge, tip section (0, -0.3, 72)

Recommended action: Monitor at next inspection; document for trending.
