Offshore wind turbine sensor measures dynamic strain
Offshore staff
ASKER, Norway – 4Subsea has introduced an autonomous sensor that measures the dynamic strain of offshore wind turbines.
The device should cut the cost of operations and maximize the life of turbines, the company claims.
Smart Monitoring Sensor (SMS) Strain is retrofittable and can be installed without the need for specialist technicians, equipment, or a clean environment.
In addition, the technology can be installed by hand on the turbine tower or using divers or ROV for subsea installation on the substructure.
Other features are low power consumption, enabling continuous logging and data storage at 10 Hz sampling frequency for 12 months.
SMS Strain sensors can also be cabled to motion sensors like the SMS Gateway (topside) or SMS Motion (subsea) to provide synchronized strain and motion data.
This allows owners to assess structural loads in correlation with deflections and response frequencies, both critical to wind turbine design.
In addition, these are IoT sensors with access to power and the internet, they will automatically start sending data to the cloud where the data is processed.
