適用范圍：This Technical Specification gives guidance to follow, as a minimum, in order to assess the feasibility ofextending the service life of a pipeline system, as defined in ISO 13623, beyond its specified design life. Pumpstations, compressor stations, pressure-reduction stations and depots are not specifically addressed in thisTechnical Specification, as shown in Figure 1.This Technical Specification applies to rigid metallic pipelines. It is not applicable to the following:- flexible pipelines;- pipelines constructed from other materials, such as glass reinforced plastics;- umbilicals;- topsides equipment;- structures and structural components.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.NOTE The assessment methodology is applicable to other changes to the design at the discretion of the user.
