ALTURA TEAM | Inspection & Preventive Maintenance (IMP)

Our IMP service combines complete technical inspection with preventive in-situ interventions, aimed at preserving blade structural integrity and preventing minor damage from progressing into major failures.

Unlike a conventional inspection, the IMP does not limit itself to documenting blade condition. We immediately act on surface defects to stabilize them and reduce the risk of propagation.

Included in the service

Preventive Intervention Included

During inspection, surface damage is immediately stabilized through:

Controlled sanding of spalling and superficial cracks

Sealing and protective repainting

Temporary protection on eroded leading edge areas

This procedure reduces moisture ingress, minimizes crack propagation, and extends service life until the next corrective campaign.

When more is needed

Management of Major Damage

When defects requiring intermediate or structural intervention are detected, the client is informed with a specific technical proposal.

Examples of complementary work

Application of LEP systems (e.g. Bergolin) on leading edge
Vortex generator replacement
Serration replacement
Localized composite repairs

Objective

Service Objective

Reduce damage growth, optimize maintenance budget, and maintain turbine availability without the need for urgent corrective campaigns.
