Reviewer 1 Report
This is a well-written paper presenting a review of methods, instrumentations, and data management strategies that are used in pipeline in-line inspection. The references to previous studies regarding this issue are highly valued. Even though this review can be considered as a good working document (technical report) as it summarizes to date developed experimental techniques, it is unclear to me what purpose the paper should serve. The content of this review can be found in some Ph.D. dissertation literature reviews or scientific textbooks on pipeline inspection. For these reasons, I do not think that the paper can be published in its present form. Without any further motivation, briefly repeating already published works cannot justify the publication of a paper.

Reviewer 2 Report
The manuscript is a review of the state-of-the-art in pipeline in-line inspection methods and the connected themes. The author provides an extensive bibliography and summarize in a somewhat effective way the cited works. The manuscript does not contain original considerations, but the review analysis is well within the scope of the journal. The language must be double-checked since the list of corrections is significant, albeit acceptable considering the length of the paper. The overall impression is positive, and it is the opinion of the reviewer that this work should be published after some minor revisions are performed.
