Beschreibung:
This document gives guidance on how 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 document, as shown in Figure 1. This document applies to both onshore and offshore rigid metallic pipelines and risers (including SCRs). It is not directly applicable to the following: — flexible pipelines; — pipelines constructed from other materials, such as glass reinforced plastics or polymers; — umbilicals (control and / or chemical conveyance service); — topsides equipment and piping (outside of pipeline system limits defined in accordance with local regulatory requirements); — pipeline protection and support structures and components. NOTE 1 The assessment process defined in clause 5.3 can be applied in the lifetime extension assessment of the above at the discretion of the user. As an example, guidance on use of the process for lifetime extension of unbonded flexible pipe is provided in Annex A. NOTE 2 Further guidance on the lifetime extension of subsea systems, including umbilicals and topsides equipment, is provided in NORSOK U-009. NOTE 3 Although the life extension of structures and structural elements is not addressed in this standard, the continued fitness-for-service of structures having a direct impact on the structural integrity of the pipeline system shall be considered throughout any period of extended operation. This shall include assessment of the implications of structural degradation on pipeline system integrity. Further guidance can be found in NORSOK N-006. This document addresses life extension, which is a change to the original design premise. It is also applicable to other changes to the design premise, such as MAOP re-ratings or a change to the conveyed fluids, at the discretion of the user. Guidance on the latter is provided in Annex B, given the potential for extension to operating life of a pipeline system being solely dependent on a change in operating fluids (such as when considering re-use of a pipeline for CCUS or for hydrogen transportation).
