ABSTRACT: In the present work, an effective algorithm for a numerical solution to the equations system modelling turbulent flow of a gas mix under a high pressure through the long offshore gas pipelines is presented. We pay particular attention to the heat exchange problem of the gas flow with the ambient through the multilayer wall of pipeline with accounting for the growing and melting processes of sea ice. Developed model allows taking into account the seasonal changes of sea temperature.
KEYWORDS: Offshore gas pipelines, sea ice, pipeline glaciation, unsteady heat exchange, ice melting.
