KINEKtron® is the world's first fully functional, tested and deployed retrofit Subsea Strain Monitoring System. The system is capable of measuring strain on structural tubular members. It combines many of Aquatec's existing innovative underwater instrumentation and communications technologies with a new and unique method for measuring strain in a robust ROV-installable package.
Key Features
- Robust permanent magnet attachment technology providing > 1-ton attachment force
- Unique multi-point strain transfer mechanism facilitating high dynamic range measurement with microstrain resolution
- Dual through-water communications
- Ultra-low-power design technology, providing up to 3 years' continuous strain data
- ROV interface for safe and effective system deployment on the structural member
Applications
- Retrofit Subsea Strain Monitoring
- Mooring Monitoring
- Pipelaying Operations Monitoring
- Wind Turbine Monopile Strain Monitoring
