The present invention provides a pipeline management supporting server capable of unifying management of attribute data of a pipe component and location information on a pipe network, efficiently detecting an abnormality of a pipeline remotely, and diagnosing the degradation state of the pipeline. The pipeline management supporting server (1) of the present invention includes: a private data processing unit (11) and a statistical calculation processing unit (12). The private data processing unit (11) includes an event data acquisition section (114) that acquires event data of a pipeline measured by a sensor(s), a measured event data storage section (112) that stores the event data of the pipeline, a pipeline database data storage section (111) that stores pipeline database data, a possible abnormality detection section (113), and an information output section (115). The possible abnormality detection section (113) identifies a pipeline and a location pertaining to the acquired event data of the pipeline with
