As the world moves towards a decarbonized future, global demand for fossil fuels continues to rise. This challenges the oil and gas industry to meet the increased energy requirements while simultaneously reducing overall emissions along the entire value chain. In this context, renewable hydrogen as a flexible energy carrier will play an important role moving the industry towards a decarbonized future. Existing gas infrastructure offers ideal conditions for storing, transporting and distributing increasing amounts of hydrogen.
As a company committed to helping operators prepare for the future, it is obvious that ROSEN supports pipeline operators in the process of change in order to extend the lifetime of their valuable assets beyond the decarbonization of the energy system. An integrated hydrogen integrity framework enables pipeline operators to make smarter decisions for the conversion of their existing gas grids to hydrogen and for the reliable operation of transporting hydrogen in all aspects of performance, safety and security.
The framework reflects the integration of service offerings for hydrogen assets into a holistic integrity management that addresses hydrogen-related threats, interactions and defects. With this integrated approach, ROSEN provides risk reduction for the injection of hydrogen into an existing network of gas pipelines.
Based on long-term experience and latest technology for gathering and processing data of embrittlement and cracks, ROSEN has already gained practical inspection experience in 100% hydrogen pipelines during their operation.
In addition, ROSEN fosters a constant knowledge exchange with numerous operators and experts to prepare engineering guidelines and practical procedures for the addition of hydrogen into the existing natural gas system without adverse effects on humanity and the environment.
This presentation will illustrate a comprehensive integrity management approach supporting pipeline operators with the conversion of their existing natural gas grids and operations for transporting hydrogen. It will summarize the potential threats and the changes or additions to current integrity management (and potentially operating) practices needed to monitor these new threats.
A 12-mile pipeline segment, 10” in diameter and installed in 1996, was set up for the transport of hydrogen. The only way to inspect hydrogen pipelines was by utilizing water as a propellant. However, this process comes at a high cost to the operator, as it requires the line be taken out of service for the inspection and the drying process. As the industry gained a better understanding, the operators pushed for more costeffective solutions
