Code of Practice Hydrogen Pipeline Systems: Design, Construction and Operation

The purpose of this Hydrogen Pipeline System COP is to provide guidance based on current knowledge for the design, construction and operation of transmission pipeline systems transporting gaseous hydrogen or blends of hydrogen and hydrocarbon fluids.
The objective of the code is to provide guidance for the safe, reliable and efficient transportation and storage of hydrogen in transmission pipeline systems that are required to conform to the AS(/NZS) 2885 series. The document also references adoption of other international codes where suitable guidance is available.
This document is intended to be updated with revised design criteria and methods as research and experience improves the understanding of hydrogen service in transmission pipelines. Although the CoP may be further developed into a published standard in the future within the AS(/NSZ) 2885 series framework, this current revision of the CoP is not equivalent to a formal, published Australian standard. The document also includes expanded commentary and background information as an informative code of practice that is more extensive than is typically covered in a standard.
