Composite materials are being widely implemented in a variety of repair scenarios within refineries - domestically and around the world. What may go unrecognized, however, are the details behind proper usage of these highly beneficial materials. Industry standards, such as the ASME~((1)) PCC-2: Repair of Pressure Equipment and Piping1, have been developed and written specifically to cover and outline procedures for the safe and successful usage of Engineered Composite Repair (ECR) Systems in this "high risk" piping environment. While these standards cover many of the details regarding qualification, training, inspection, and other considerations associated with the ECR implementation process, there are an unlimited number of concerns when using them in a live, plant environment. The repair of non-leaking (Type A) and leaking (Type B) piping may both be accomplished by using an ECR system, however not only the design, but also the site requirements are considerably different for each. Understanding the specific limitations and abilities of the ECR system being used is only the beginning of the needs for an installation technician. From assessment to design to planning and executing, there are a variety of operating and design parameters and conditions that must be known and communicated in order to complete a successful composite repair installation. This paper will discuss some of the primary concerns, considerations, and needs typically encountered when using ECR systems to repair live, operating piping systems in a plant environment.
