Course description

To provide knowledge of the phenomena relative to pipeline hydraulics, as well as main methods for friction loss calculation and flow simulation.
Upon completion of the course, participants:
•    are able to calculate/estimate the friction losses in a pipeline and fittings for a single phase flow,
•    know the flow patterns for multiphase flow and the main parameters that influence them,
•    know the hydrodynamic phenomena relative to multi-phase flow for gas dominated or oil dominated systems,
•    are sensitive to flow assurance issues, relative to flow in a pipeline,
•    have a first experience in pipeline simulation.



Graduate Engineers, whose activity is related to the design, construction and/or operation of Oil & Gas production facilities.
