Summary:Due to the enclosed air interlayer in the J-tube section, it has the potential to limit the current-carrying capacity of offshore wind farm export cables. The standard calculations outlined in the IEC guidelines are deemed inadequate for this unique laying method. Conducting fluid simulations can be time-consuming and challenging to implement in practical engineering scenarios. This article introduces a rapid calculation approach for determining the current-carrying capacity of submarine cables in J-tube sections, utilizing a semi-empirical correlation formula for natural convection in a vertical enclosed annular space and an axial heat transfer model for submarine cables. A comparative analysis between the proposed method and thermal-fluid coupling numerical simulations demonstrates the effectiveness of the proposed approach.
