Abstract (en)
[origin: CA3114323A1] The invention relates to identifying the occurrence of a defect (11) in a pipeline (10) by means of estimation, wherein at least one first indicator (40) is identified by a first detection means (20) assigned to a first detection location (30), from which indicator a first estimation value regarding the occurrence of the defect (11) in the pipeline (10) is determined by means of a first estimation function, and at least one second indicator (41-43) is identified by at least one second detection means (21-23) assigned to a second detection location (31-33), from which indicator at least one second estimation value regarding the occurrence of the defect (11) in the pipeline (10) is determined by means of at least one second estimation function, and an overall estimation value is determined from the first estimation value and the at least one second estimation value by means of an overall estimation function by taking into account the respective positions of the first detection location (30) and of the second detection location (31-33), from which overall estimation value the occurrence of the defect (11) is estimated.
