A 3D parametric thermal analysis of submarine three-core power cables

Abstract

This paper presents the main features of a 3D FEM-based modelling framework of submarine three-core power cables with the final aim of estimating the ampacity of this type of cables when operating at certain conditions (buried in the seabed in steady-state). This assessment provides valuable information for the cable manufacturer during the design stage and for the owner of the evacuation line mostly in the planning stage, apart from being used as a reference for the development of other less computationally intensive analytic models. Moreover, the paper analyzes the impact that some design parameters have on the temperature of the cable, providing same concluding remarks.
