Analysis of Temperature Field Simulation for Multi-layer Umbilical Cable of Remotely Operated Vehicle

As a crucial component of Remotely Operated Vehicle (ROV) power and signal transmission, umbilical cable needs to be wound on winches under working conditions. During operation, temperature rise of umbilical is easily affected by internal losses. Prolonged exposure to high temperatures can accelerate insulation aging and even induce breakdown. To ensure safe operation of umbilical cable during operation, electromagnetic and temperature characteristics need to be analyzed. Based on finite element simulation software COMSOL, multi-physical field coupling model for electromagnetism and temperature fields was established. Combining barrel structure, number of layers of cable winding, and factors such as heat conduction and heat convection during operation, characteristics of wire core loss and temperature distribution and heat dissipation characteristics after multi-physical field coupling were studied. Influence of umbilical on temperature field distribution under different loads and windings was analyzed. Results could provide theoretical support for the design of umbilical cable and configuration of multi-layer umbilical Cable.
