COMPARISON OF SOIL MODELS IN THE THERMODYNAMIC ANALYSIS OF A SUBMARINE PIPELINE BURIED IN SEABED SEDIMENTS

Abstract

This paper deals with mathematical modelling of a seabed layer in the thermodynamic analysis of a submarine pipeline buried in seabed sediments. The existing seabed soil models: a “soil ring” and a semi-infinite soil layer are discussed in a comparative analysis of the shape factor of a surrounding soil layer. The meaning of differences in the heat transfer coefficient of a soil layer is illustrated based on a computational example of the longitudinal temperature profile of a -kilometer long crude oil pipeline buried in seabed sediments.

Keywords:

submarine buried pipeline, seabed thermal models, shape coefficient, heat transfer coefficient, longitudinal temperature profile
