Guidelines for Reliability Based Design and Assessment of Onshore Natural Gas Pipelines
A set of guidelines for the application of Reliability Based Design and Assessment (RBDA) of onshore natural gas pipelines has been developed. These guidelines contain a general overview of RBDA methods and a discussion of the key issues associated with applying them to pipelines.
Summary:
A set of guidelines for the application of Reliability Based Design and Assessment (RBDA) of onshore natural gas pipelines has been developed. These guidelines contain a general overview of RBDA methods and a discussion of the key issues associated with applying them to pipelines. Requirements for the application of RBDA are also given, specifying the design conditions that must be considered and the reliability targets that are to be met. In addition, the guidelines provide the technical information required to apply RBDA including methodologies to identify relevant limit states, construct limit states functions, develop probabilistic models for uncertain input parameters and estimate the lifetime reliability. Two example applications are given: one for the design of a new pipeline segment, and the other for a class upgrade assessment of an existing segment.
