This Standard covers the use of in-line inspection systems for onshore and offshore gas and hazardous liquid pipelines. This includes@ but is not limited to@ tethered or free flowing systems for detecting metal loss@ cracks@ mechanical damage@ pipeline geometries@ and pipeline location or mapping@ The Standard applies to both existing and developing technologies. This Standard is an umbrella document that provides performance-based requirements for in-line inspection systems@ including procedures@ personnel@ equipment@ and associated software. The Standard includes the following sections: ? Terms and Definitions. ? Systems Qualification Process and Incorporated Standards - Overall process description with referenced qualification requirements for in-line inspection personnel and equipment. ? In-Line Inspection System Selection - Requirements for selecting an in-line inspection system for a specific pipeline application. ? Qualification of Performance Specifications - Requirements for establishing@ documenting@ and validating performance specifications of in-line inspection systems. ? System Operational Validation - Requirements that must be met before@ during@ and after running an in-line inspection system to assure that the system functioned properly. ? System Results Verification - Requirements for verifying that the results of an inspection are consistent with the performance specification. ? Reporting Requirements. ? Quality Management System - Requirements for documentation@ quality control@ continuous improvement@ and system review.
