Thermal modelling of electro-mechanical cables for ROV applications

A method for predicting the steady-state and transient temperature distributions for electromechanical cable reels is shown. A generalized finite-difference analysis technique is introduced which generates two-dimensional steady-state solutions and one-dimensional transient solutions for cable temperatures. The method allows a variable number of layers, turns per layer, cooling methods, cable resistive heating levels, and ambient conditions. An example application of the model to an ROV (remote operated vehicle) umbilical cable is presented.>
