Low Computational Cost Model for Convective Heat Transfer From Submarine Cables

The ampacity of submarine cable circuits is strongly influenced by heat transfer in the marine environment surrounding cable. It has been demonstrated previous work that for high permeability sediments convective can play a significant roleusing both bespoke two dimensional models and experimental investigations [T. J. Hughes, 2016, C. Emeana, 2016]. This paper introduces one model which capable calculating temperatures within conductive sediments. Agreement between simulation was found to be 1.5 °C. used demonstrate power cables may significantly increased due transfer. Further, offers savings computational time cost compared equivalent model. allows analysis large DTS data sets order calculate: dynamic ratings; burial depths; long-term (annual decadal) performance
