Summary
Offshore wind capacities may exceed direct electricity absorption in energy systems. Water electrolysis using renewable sources enables greater renewable integration and hydrogen use in the industry. For this purpose, umbilical cables, incorporating both power cores and hydrogen pipes, may be used. To assess their thermoelectric performance, standardized methods are insufficient: they overlook pipe effects on current rating and electromagnetic interference, under either normal operating or faulty conditions. Instead, more sophisticated models are required, employing numerical methods, such as the Finite Element Method (FEM) and

This paper presents the thermoelectric analysis conducted for a novel, 132 kV umbilical cable with integrated stainless-steel hydrogen pipes for inter-array applications. A magnetic analysis is coupled with a thermal model, both developed in FEM, to evaluate cable losses and temperatures under balanced conditions; to assess the cable performance under unbalanced, fault conditions, models developed through
EMT-like software are used; contingency scenarios, such as pipe fractures, are also discussed.
The derived results verify the robustness of the selected design, being achieved via the use of high-quality semiconductive material on the pipe coating.
