Project Code: 36214

Start date and planned duration: January 2025, 24 months

Objective

Develop the database and machine learning programme for the material properties (parent, HAZ and welds) in hydrogen gas environment, based on the testing results (from the existing testing results and literature results)
Carry out the fatigue and fracture testing with crack monitoring techniques in air to develop the live monitoring system in the lab environment in air condition
Complete the interface and the integration of all the data and the live monitoring system to the structural integrity assessment software
Application of the developed live structural integrity monitoring system for small scale pipeline welds material testing in pure hydrogen gas condition

Project Outline

Develop the live structural integrity monitoring system for pipelines in hydrogen gas condition in a lab scale, to simulate the real condition. The sensor for thickness monitoring, crack detection and monitoring will be identified; and then the database and machine learning programme will be developed for the material properties in hydrogen based on the testing results; lastly the interface and the integration of all the data and the structural integrity assessment software will complete so that the structural integrity status can be monitoring in real time.

Industry Sectors

- Oil and Gas

- Energy Transition

Benefits to Industry

A live structural integrity monitoring system for pipelines operating in hydrogen environments delivers measurable safety, reliability, and cost advantages across the oil and gas and energy transition value chain. It reduces failure risk from hydrogen-assisted cracking and accelerates safe deployment of hydrogen infrastructure, while cutting inspection costs and downtime.
