Heat transport

We plan and support heat transport in the near-surface subsurface for buried power cables and district heating pipes. We assess the thermal capacity of routes, the interaction with the ground and the temperatures in the subsoil.

Based on coupled models and technical standards, we prepare reliable planning and verification documents for your project. Our clients include grid operators, municipal utilities, planners and project developers.

Heat transport

Our range of services

Thermal verification

  • Cable rating calculations
  • Thermal capacity of cable and pipe routes
  • Subsoil temperature forecasts

Modelling & simulation

  • Coupled heat and moisture transport studies
  • Static and transient 2D analyses for standard cross-sections along routes
  • Static and transient 3D analyses, for example for route crossings, joint pits and building entries

Complex boundary conditions

  • Non-linear analyses with surface energy balance (sun, wind, precipitation)
  • Non-linear material properties, for example during freeze-thaw cycles
  • Planning and verification documents for standards and permits
