Technology advancements in materials, techniques, new products, procedures, etc. offer pipeline companies the opportunity to extend the safe life of assets in place. A comprehensive Pipeline Repair Manual is needed to address these new advances, provide engineering guidance to choose appropriate repair techniques for specific defects in pipelines. This new updated Pipeline Repair Manual provides guidance to pipeline operators as they: (1) choose appropriate repair techniques for specific defects in in-service pipelines; (2) develop or enhance their own procedures and/or manuals for pipeline repairs; (3) or train or qualify maintenance personnel. The manual presents a catalog of known pipeline repair techniques, and discusses the various types of pipeline defects that lend themselves to being repaired while in-service. A matrix is provided to match defects in need of repair with appropriate repair methods. In addition defect assessment methods are presented as are safety considerations related to making in-service repairs. The manual is divided into the following major sections: (1) Response to the discovery of an anomaly or defect - this section presents safety issues and defines critical information that is required to make an appropriate repair response. (2) Pipeline repair methods - this section describes the known methods of repairing in-service pipelines. (3) Appropriate repairs for various types of defects - this section matches the types of defects that are likely to be encountered in in-service pipelines with appropriate repair methods. (4) Repair methods in Europe - this section was added after a review of the draft by a committee of pipeline repair specialists from several European pipeline operators who are members of the Group Europeene de Recherches Gazieres (GERG). It contains suggestions made by the committee to enhance the substance of this manual and to inform readers concerning European practices. (5) Guidelines for repair procedures - this section presents a model procedure, which a pipeline operator may use to create, enhance, or evaluate repair procedures.
