Introduction: The Pipeline Life Cycle

Pipelines are the ideal modality for the transport of large volumes of liquid and gaseous products, and solids in suspension over long distances. This chapter initially approaches the origins of pipeline transport, its evolution, and its role over time. The life cycle phases of a pipeline undertaking are presented from its conception until its decommissioning and definitive withdrawal from operation. The phases are described starting with the identification of the opportunity of implementing a new project, as well as the considerations given to technical, construction, economic viability, legal, environmental, and undertaking management aspects. The new questions introduced by the energy transition and the necessity of achieving a social license for the pipeline installation are also briefly described. The chapter summarizes and introduces the content of the material that will be presented throughout the Handbook of Pipeline Engineering.
