Description:
In the past five years, a multitude of new inspection technologies have emerged as viable sources of pipeline condition data. Furthermore, many of these new technologies provide quantitative (versus qualitative) data that can significantly improve diagnostic and predictive capabilities. USEPA has recognized as part of its Aging Water Infrastructure Research effort, Condition Assessment of Wastewater collection Systems, an emerging capability gap within the industry on how to best utilize these new technologies for condition assessment and pro-active asset management. In addition to the identification and evaluation of current and emerging innovative condition assessment technologies, this paper will describe a technology selection roadmap for the optimization of pipeline inspection and condition assessment that directly addresses this need. The roadmap is aimed to facilitate the selection of inspection technologies based on inputs from the asset owner that include: The fundamental condition assessment questions; Prior information about he condition and construction of the asset; Relative criticality of the asset; Cost of the inspection technologies in isolation or combination; Quality of Service (QoS) of inspection technologies in isolation or combination. More specifically, the asset owner’s information needs and the asset’s relative criticality are the primary drivers in the technology selection roadmap. For a given pipeline or system, the costs of employing a particular technology are balanced with its Quality of Service. In practical terms, this means that asset owners can use this roadmap to avoid unnecessary costs incurred by over-inspecting. Similarly, these same asset owners can avoid unnecessary risks accumulated by under-inspecting their most critical pipelines.
