In cooperation with the working group “Mathematical Statistics” of the University of Bremen, the project “Temperature Error Estimation (TEEst)” was launched on 15 May. The components of a sediment-cable temperature model are statistically modeled to arrive at an error estimate for the cable temperature under real conditions. The electric utility companies can then dimension their cables resource-conserving but nevertheless safe. The project is supported by funds from the European Regional Development Fund (ERDF) and the state of Bremen.
