Cable Monitoring for Offshore Wind

4Subsea delivers key decision support for optimised production from offshore wind turbines. Cable failure is a common source of production loss and thus an important cost driver for wind field operators. We provide a digitised cable monitoring solution with autonomous, retrofit sensors providing key data on the status of the cables, data analysis by 4Subsea’s domain expertise and prediction analysis delievered on™. This enables operators to make better decisions on maintenance and equipment replacement, securing production uptime.

Typical Challenges for Operators


Do any of these apply to your offshore wind assets?
  • Cable failures due to movements, temperatures, or loads outside design parameters of equipment
  • Loss of production, either stop in production or production downtime due to cable issues
  • Sub-optimal replacement scheduling; repairing or replacing equipment due to age rather than actual status of cables


4Subsea provides key decision support with a digital twin that enables wind farm operators to “know it before it happens” and fix it before it gets big.
