Natural gas from the Norwegian continental shelf (NCS) is processed at the Kollsnes gas treatment plant in western Norway and exported through two pipelines to continental Europe. The export facility consists of five parallel compressor trains and a crossover leg between the two export pipelines. Customers have the opportunity to make varying nominations, which the plant must satisfy. Several compressors operating in parallel, crossover possibilities and alternating pipeline pressures and nominations present challenges for identifying optimum operation procedures at the export facility. Several different ways to operate the facility are available. Each of these may be equal in terms of meeting system requirements, but may differ for energy efficiency. The objective of the work is to establish guidelines for optimum operation of the compressor station. This implies increasing system energy efficiency by minimizing specific power consumption and maintaining operational flexibility.
