Organizing the crossing of a gas pipeline over guduca canyon

Abstract

Gas wells are located far from the consumers. Gas is therefore transported from them using a system of main gas pipelines. A gas pipeline is a closed technological unit consisting of a pipeline with its accompanying equipment and buildings. It traverses different terrain and some of the most challenging among those are waterways, especially when they are also an active naval route. The crossing of a gas pipeline over the Guduca Canyon was a very demanding task, given that the crossing point has a very steep and rocky western slope and a somewhat less steep eastern slope made up of dirt and limestone rock. The crossing was done by a combined method of drilling through the rock on the western slope and inserting the pipeline into the bore, and laying the pipeline in a trench for the rest of the crossing. After the pipeline was connected, but before it was put into use, it was tested to ensure that it met the required standards of quality. © 2014 The Authors. Published by Elsevier Ltd.
