PR-186-204504-R01 PRCI Pipeline Repair Manual 2021 Edition

This 2021 Edition of the PRCI Pipeline Repair Manual is an updated version of the original manual that was published 1994 and updated in 2006. The 2021 Edition discusses response to anomaly or defect discovery, reviews repair methods, identifies appropriate repairs for various types of defects, and provides generic guidelines for use of various repair methods. DNV has reviewed existing and emerging pipeline repair technologies and evaluated them in comparison with those in the previous versions of the manual. The review was based on published literature, vendor literature, and industry experience. The 2021 Edition of the Pipeline Repair Manual contains added and updated information on repair technologies gleaned from the literature, vendor publications, and industry experience. Without losing sight of well-established repair methods that have served the industry well, the most recent update focused on repair methods and practices that are commonplace or have emerged and have become commonplace since the previous version of the manual was published. This manual does not identify or prescribe all repair methods for all defects or anomalies. Instead, the manual concentrates on commonly encountered defects and commonly used repair methodologies for those defects. Other repair techniques may be equally valid depending on the specific conditions encountered. This 2021 Edition of the manual does not provide specific guidance on current regulations or on code interpretation. National and international codes and regulations change rapidly, and code interpretation is best left to individual companies. Footnotes identify specific pertinent sections of selected US regulations. Click here for related webinar.
