23、 Introduction The International Standard ISO 13623 allows the use of innovative techniques and procedures such as reliability-based limit state methods providing the minimum requirements of ISO 13623 are satisfied. This International Standard provides the supplement to ISO 13623 in giving recommenda

24、tions and specifying the framework and principles for the application of the probabilistic approach, i.e. “reliability-based limit state methods”. Pipeline integrity management during design and operation are performed by the following two limit state approaches: a deterministic approach, with the u

25、se of safety or usage factors applied to characteristic loads and resistances; and a probabilistic approach, based on structural reliability analysis applied to the relevant limit states, e.g. reliability-based limit state methods. Both approaches satisfy the safety requirements; implicitly by the d

26、eterministic approach (via earlier-calibrated safety factors) and explicitly by the probabilistic approach (a direct check on the actual safety level) as illustrated in Figure 1. Significant differences exist among member countries in the areas of public safety and protection of the environment. Wit

27、hin the safety framework of this International Standard, such differences are allowed for and individual member countries can apply their national requirements for public safety and the protection of the environment to the use of this International Standard.

28、18E8EA43EDB30F09CC9B7EF8DD9NormCD - Stand 2007-03 1 Scope This International Standard specifies the functional requirements and principles for design, operation and re-qualification of pipelines in the petroleum and natural gas industries using reliability-based limit state methods as permitted by I

29、SO 13623. Reliability-based limit state methods provide a systematic way to predict pipeline safety in design and operation. This International Standard supplements ISO 13623 and can be used in cases where ISO 13623 does not provide specific guidance and where limit states methods can be applied, su

30、ch as, but not limited to, qualification of new concepts, e.g. when new technology is applied or for design scenarios where industry experience is limited, re-qualification of the pipeline due to a changed design basis, such as service-life extension, which can include reduced uncertainties due to i

31、mproved integrity monitoring and operational experience, collapse under external pressure in deep water, extreme loads, such as seismic loads (e.g. at a fault crossing), ice loads (e.g. by impact from ice keels), situations where strain-based criteria can be appropriate. This document applies to rig
