In offshore fields, the quality indicators of the well product are subjected to change when it passes the initial preparation stage at the collection points and is transported to the shore. Researches show that most of the problems that arise in the collection points of fields operated in marine conditions are related to multi-component and multiphase flows. Contamination from the inner surface of the pipeline due to the internal phase transformations of the pipeline causes an increase in the operation and energy costs of the collection transport system. Blockages are formed in underwater pipelines when the liquid and mechanical particles in the transported gas are separated and settle inside the pipe.
