FOR Wind asset owners, turbine service firms and heavy-lift contractors
Treat a component exchange as a defined project
Replacing a gearbox, generator, blade or nacelle can create a temporary project within an operating wind facility. Identify the work package, replacement value, lifting sequence and responsibility for old and new components. The owner’s operating policy, the service contractor’s program and any installation coverage may each address only part of the activity.
Explain whether the replacement is like-for-like, an upgrade or a response to a known defect. A planned improvement and accidental damage are different insurance questions. Record the point when the replacement leaves the supplier, enters site storage, is lifted into position and returns to operational service; those transitions should not depend on an informal assumption.
Review the lift and surrounding property
A dropped component can damage the turbine, crane, nearby equipment and third-party property. Review riggers liability, installation property, crane physical damage and contractual allocation without assuming one contractor policy protects every interest. Check the treatment of property being lifted, property in care and the contractor’s own work under the actual forms.
The lift plan and ground conditions belong to qualified engineers and lifting specialists. The insurance team needs the resulting scope, equipment values, subcontractor structure and any required survey or notification. If the owner supplies the component or crane access area, clarify how those responsibilities affect indemnity and claims coordination before mobilization.
Separate warranty remedies from interruption protection
A warranty may pay for a replacement part but exclude mobilization, lifting or revenue loss. Review the service agreement’s remedy, liability cap and responsibility for consequential costs alongside property and business-interruption insurance. Known defects, wear or serial issues may be treated differently from sudden accidental damage, and the policy language needs individual review.
Model the full restoration sequence: procurement, transport, suitable weather, crane availability, installation, testing and reconnection. An available component does not guarantee an immediate repair. For offshore work, vessel availability and access conditions can be central. Identify which delays follow insured damage and which arise from maintenance, upgrade decisions or unrelated commercial constraints.
Document condition before and after the exchange
Provide component serial numbers, inspection findings, failure analysis, maintenance history and the replacement schedule. Preserve damaged parts and relevant operating data subject to insurer and technical guidance; returning a failed item under a supplier’s exchange process can affect evidence. Clarify ownership and disposal responsibility for removed components.
Before the turbine returns to service, reconcile acceptance documents, testing results and any remaining defects with the coverage transition. A project completion certificate should not conceal unfinished work or unresolved allegations. Keeping one coordinated file allows the owner, maintenance provider and lifting contractor to evaluate their separate obligations while preserving a clear account of the actual replacement activity. Retain the final component acceptance record.
