For many large pipeline projects with multiple compressor stations, detailed optimization studies have to be performed in the planning phase. These studies not only have to take the pipeline hydraulics into account, but also in great detail the rotating equipment performance. Historically, rotating equipment was treated as blocks of constant power, without detailed modelling of unit arrangement, compressor efficiency characteristics, and gas turbine off design behavior. This study shows the advantages of more precise analysis and the inclusion of equipment characteristics. An analysis for a typical 42" pipeline with the capacity of 2 Bcfd with 4 compressor stations is used as an example. The four different station configurations were analyzed, with single and multiple units and with latter one at series and parallel units configurations. The pipeline recovery rate was analyzed when one unit on one station was down. Thus, data-based statements on flexibility and fuel economics can be made, based on the station configuration, and the number of units.
