This technical webinar will take a deep dive into the engineering principles, modelling approaches, and design verifications required to ensure safe, reliable, and thermally efficient HDD installations.

🔍 Topics Covered

➤ HDD Fundamentals for Power Cables
Understand how HDD differs from traditional open-cut methods, including the effects of bore geometry, pipe deflection limits, drilling fluid, and installation stages.

​​➤ Cable and Pipe Configuration Options
Compare casing and duct layouts—single large casing pipes, multiple ducts, and direct-buried options—to balance protection, retrievability, and ampacity performance.

​​➤ Thermal Design and Ampacity Calculations
Explore how burial depth, soil thermal resistivity, and filling materials influence cable ratings. Learn when to apply IEC 60287 analytical methods versus FEM-based models for HDD systems.

​​➤ Soil Thermal and Moisture Behaviour
Investigate how soil drying, groundwater levels, and temperature gradients affect long-term thermal resistance and how to model these factors in FEM software.

​​➤ Landfall and Submarine Transition Zones
Learn how to mitigate the thermal bottlenecks in landfall sections using advanced design approaches, including sheath bonding strategies and optimised backfill.

​​➤ Validation with CIGRE and FEM Modelling
See how ELEK’s validated FEM approach compares with CIGRE benchmark studies, ensuring engineering accuracy in even the most complex geometries.

​​➤ Live Software Demonstration
Watch practical examples modelled in ELEK Cable HV™, including cable systems in ducts, grout-filled casings, and deep HDD sections—showing real-time ampacity computation and sensitivity analysis.

​​This technical webinar brings together decades of collective research and real-world experience, offering a rare chance to gain design insights not covered in textbooks or standards. Whether you’re specifying new transmission corridors, designing offshore export cables, or managing underground routing constraints, this session will equip you with the analytical tools and confidence to optimise your HDD cable designs.
