Question: The new Appendix B in AS2885.1-2018 appears to provide information that almost discourages the use of a 0.8 Design Factor. Is this the intent?

Answer: (James Czornohalan)

Not at all. However, selection of a 0.8 design factor requires a significant engineering effort, and may result in hidden extra project costs. The guidance is to ensure that the decision to design and build a pipeline with a 0.8 design factor is taken seriously, and to advise that for shorter or smaller pipelines the costs saved in wall thickness may not outweigh the costs for the extra engineering effort.
