In a damage event, every hour counts – and every decision.
Major damage to a wind turbine is a technical, commercial and legal event
all at once. We orchestrate all parties involved, secure evidence and claims,
and guide the asset back into revenue in a controlled manner.

Commissioning of independent experts
Selection and commissioning of qualified experts, support during the
damage assessment and assurance of robust documentation that will
stand up in court.
03
Coordination with investors & insurers
Transparent communication with owners, banks and insurers –

Acute damage event at a Vestas turbine?
The earlier we are involved, the better claims can be secured and downtime shortened.
Rotor blade damage after a lightning strike: from standstill to a planned blade replacement.
A 3 MW-class Vestas turbine in a German onshore wind farm is at a standstill following
lightning damage to a rotor blade; the manufacturer's inspection classifies the blade
as beyond repair. VentusTech is managing the incident on behalf of the operator – from
the immediate situation through expert assessment and insurance to the blade replacement with Vestas.
Operator, wind farm and location are anonymised. Process and roles correspond to the real engagement.
Turbine
Vestas · 3 MW class · Onshore
Damage pattern
Lightning damage – laminate, blade tip, lightning protection system
Manufacturer's finding
Highest damage category · Blade replacement
Order of magnitude
High six-figure euro range plus business interruption
Status
Ongoing – blade replacement in preparation
Initial situation
A drone inspection reveals damage from a lightning strike on one rotor blade:
laminate damage in the inner third of the blade, melting at the blade tip and a
damaged lightning protection system with increased contact resistances. The turbine
is safely shut down (idling mode) and continuously monitored – with ongoing loss of revenue.
Process
Step 1
Manufacturer's inspection by rope access
Vestas inspects the damaged blade by rope access. Result of the blade inspection report: highest damage category, a repair is not technically feasible – recommendation: blade replacement.
Vestas Service
Step 2
Case intake and immediate situation
VentusTech takes on the case as the operator's technical and contractual adviser and incident manager: safety and standstill assessment, review of all findings, coordination with the broker and machinery insurer. From this point on, the operator receives regular management updates in traffic-light status.

Step 3
Independent expert assessment on site
VentusTech coordinates the selection and appointment of an independent expert and supports the multi-day assessment on site – including a rope access assessment of the intact rotor blades. Maintenance logs, status data, lightning data and blade reports are consolidated into an auditable claim file.

Step 4
Insurance and contractual position
In-depth coordination with the broker and machinery insurer. The technical basis for classifying the damage from an insurance and contractual perspective is prepared in a structured form – as a basis for decision-making by the operator and its advisers.

Step 5
Blade replacement in preparation
Replacement blade and transport capacity reserved at an early stage. Transport study, access road, crane pad and delivery dates are continuously updated in the joint project plan with Vestas. Status: ongoing.

Working with Vestas
In a blade replacement, the manufacturer is the central partner: service case,
blade inspection, replacement blade, transport and crane are all handled through
Vestas. VentusTech leads the coordination on behalf of the operator – technically
as equals, contractually clear and with the shared goal of keeping downtime as short as possible.
Service case and blade inspection report as the shared technical basis
Scope of work clearly defined together with Vestas – limited to what is technically necessary
Replacement blade and transport capacity reserved at an early stage to limit downtime – in coordination with the broker and insurer
Project plan (transport study, upgrading of access road and crane pad, delivery dates, crane and logistics planning) jointly updated and closely tracked against the schedule
Current status
The blade replacement with Vestas is in preparation, the replacement blade and
transport capacity are reserved; coordination with the broker and insurer is running
in parallel. Already achieved: a complete, auditable claim file, a clearly defined
scope of work and a project plan shared with all parties involved. The operator makes
decisions on an up-to-date, robust basis.
Three lessons
In the event of lightning damage, obtain an independent expert assessment early – it is the basis for insurance and contractual matters.
Build the documentation from day one so that it withstands any scrutiny: maintenance logs, status data, lightning data and blade reports belong in a single file.
Downtime costs money every day: define the scope of work with the manufacturer early, secure the spare part and logistics, and agree the approach with the broker and insurer.
Anonymised case study from an ongoing engagement: operator, wind farm, location,
turbine identifier, insurer, broker, experts, other advisers, amounts and calendar dates
are deliberately not named; the manufacturer only because the blade replacement is
manufacturer-specific. Vestas is a trademark of its respective owners – VentusTech
Consulting provides manufacturer-independent advice; no business affiliation is claimed.

We assess the situation, secure the documentation and coordinate experts, insurer and manufacturer – at short notice in a major damage event.
What the contract guarantees – and what actually runs.
The gap between the availability guaranteed in the service contract and the
availability actually achieved often means real money. We review the availability
calculation, uncover calculation gaps and ensure that the maximum actual
availability is both achieved and contractually enforced.
