In the present work an optimization study was conducted with the objective of providing pipeline operators with a simple, spreadsheet-based computational tool to help decrease the electrical energy consumption associated with a particular transport operation. The methodology proposed encompasses the construction of a database of information on the pipeline regarding pumping power consumption, for all possible pumping arrangements and flow rate ranges considered viable for the pipeline. This database is fed to a spreadsheet programmed to calculate the minimum pumping cost for a particular operation. This calculation takes into account, the volume of product to be transported, start and finish times, fluid properties, and the possibility of the existence of a low and a high electricity tariff based on geographical location and time of the day. The methodology was applied to the ORBEL II pipeline in Brazil, and two case studies were conducted. Significant cost savings were obtained by the use of the methodology developed.
