Offshore Wind Insurance: Installation, Cables and Repair Delays
Assess construction and operational property, marine transit and installation, subsea cables, liabilities and any requested delay or business interruption cover.
AI-generated editorial illustration.
An offshore wind farm's insurance exposure extends beyond turbines. Cables, installation vessels, weather access and the availability of repair resources can determine how a physical casualty affects the project.
What should offshore wind insurance consider?
Assess construction and operational property, marine transit and installation, subsea cables, liabilities and any requested delay or business interruption cover. Identify who owns each asset and which party bears risk during installation and handover. Repair delay is not automatically insured merely because the damaged equipment is covered.
Map the assets and repair dependencies
| Asset or dependency | Question for the insurance review |
|---|---|
| Export and array cables | Which sections, values and repair methods are included? |
| Turbines and foundations | How are design, installation and operating phases treated? |
| Specialist vessels | Who bears availability and mobilisation costs? |
| Grid connection | What dependencies affect the financial loss calculation? |
Allianz's offshore wind risk report identifies cables and repair-related challenges as important considerations. Its historical portfolio statistics are not used here as current market rates or predictions for an individual project.
A fictional cable repair
A cable fault requires investigation, a replacement section and a suitable vessel. The owner should distinguish the physical repair from mobilisation, weather waiting and lost generation. Whether each is insured depends on the wording and the cause of the fault.
Preserve test results, installation records, monitoring data and repair decisions. A long outage does not by itself establish that the whole period is recoverable under business interruption cover. Other constraints may affect the calculation.
Explain the construction-to-operation transition
For underwriting, provide project layout, asset values, technology, contractors, installation schedule, testing and acceptance process, operating arrangements and loss history. Identify phased commissioning and outstanding work. Explain spare parts and repair access without presenting a contingency plan as a guarantee of quick recovery.
Review defects, serial loss, testing, subsea operations, contractual liability and financial loss provisions. Ask how deductibles apply to several affected assets and whether a common cause changes aggregation. The answer must come from the actual policy.
Coordinate contractor and owner interests
Compare installation contracts, warranties, indemnities and insurance obligations. A contractor's responsibility for a defect does not automatically provide the owner with immediate funds for all resulting losses. Preserve recovery rights while coordinating urgent work.
Following a casualty, notify relevant insurers, secure technical evidence and document mitigation options. Separate repair costs from lost revenue and from costs incurred for an unrelated improvement. Obtain required consent before settlement or disposal of evidence where practicable.

Key takeaways
- Assess construction and operational property, marine transit and installation, subsea cables, liabilities and any requested delay or business interruption cover.
- No. Any business-interruption protection has its own trigger, waiting period, limits and other conditions.
