Real-Time Thermal Rating Monitoring
Monitor cable core temperature in real time and calculate how long it takes to reach maximum thermal capacity.


Extend the lifetime of your subsea power cable with RTTR.
With RTTR, you can monitor the temperature in the core of the undersea cable continuously and calculate remaining thermal capacity.
- Continuous distributed temperature sensing
- Real-time thermal capacity calculation
- Predictive alerts before thresholds
- Historical trend analysis
We take care of your subsea power cables.
Real-Time calculations
By using the Real-Time Thermal Rating service you get real-time and actionable insights into the core temperature of your subsea power cables.
Temperature reporting
Generate customizable temperature reports for specific sections of cable, with the ability to adjust thresholds and granularity as needed. Get alerts when cable gets too hot.
RTTR simulations
Define your circumstances in terms of load and time, and instantly get a visual forecast of how hot your cable will get under current or worst-case conditions.
Historic temperature
Get access to historical data and see past temperature and load readings. Analyze the historic data for the entire power cable or just a few selected locations.
Extend cable lifetime
With accurate historical temperature and load data at your fingertips, you have all the tools available to ensure long-term cable integrity and extend the lifespan of the subsea cable.
Maximize efficiency
With real-time calculations of core temperatures, it becomes easy to plan cable loads and minimize the need to curtail wind turbine generators, while still ensuring safety.
