DIN CEN ISO/TS 12747

Abstract

This Technical Specification gives guidance to follow, as a minimum, in order to assess the feasibility of extending the service life of a pipeline system, as defined in ISO 13623, beyond its specified design life. Pump stations, compressor stations, pressure-reduction stations and depots are not specifically addressed in this Technical Specification, as shown in Figure 1. <br>This Technical Specification applies to rigid metallic pipelines. It is not applicable to the following: <br>- flexible pipelines; <br>- pipelines constructed from other materials, such as glass reinforced plastics; <br>- umbilicals; <br>Topsides equipment; <br>- structures and structural components. <br>This Technical Specification is limited to life extension, which is an example of a change to the original design. Other changes, such as MAOP up-ratings, are excluded. <br>NOTE The assessment methodology is applicable to other changes to the design at the discretion of the user.
