1. Introduction
This document specifies the advised operational and reporting requirements for tools to be
used for geometric measurement, pipeline mapping, metal loss, crack or other anomaly
detection during their passage through steel pipelines. The tools may pass through the
pipeline driven by the flow of a medium or may be towed by a vehicle or cable. The tools
may be automatic and self-contained or may be operated from outside the pipeline via
a data and power link.
This document has been reviewed and approved by the Pipeline Operator Forum (POF).
It is stated however, that neither the members of the POF nor the Companies they represent
can be hold responsible for the fitness for purpose, completeness, accuracy and/or
application of this document.
A draft version of this document has been sent for comments to Intelligent Pigging
Contractors as listed in Appendix 2. The POF like to thank the Contractors for their
constructive feedback.
During the update of this specification, the API 1163 “In-Line Inspection Systems
Qualification Standard” have been reviewed and some terminology has been brought inline (e.g. confidence changed into certainty).
This document is intended to serve as a generic in-line-inspection specification and thereby
cannot cover all pipeline or pipeline operator specific issues. POF members and other users
of this specification are therefore free to add or change requirements based on their specific
pipeline situation. To support the pipeline operator in specifying/detailing some optional
items in this document, a guideline with a short description of these items is given in
Appendix 1. 640
