| Project Number | 522 |
| Date of Summary | March 15, 2007 |
| Subject | Methodologies for Measuring and Monitoring Hydrogen for Safety in Advanced High Strength Linepipe Steel Applications. |
| Performing Activity | Colorado School of Mines |
| Principal Investigator | Olsen and Mishra |
| Contracting Agency | Minerals Management Service |
| Estimated Completion | Completed |
| Description | Project will investigate methodologies for measuring and monitoring hydrogen for safety in advance high strength linepipe steel applications for use in offshore operations as well as onshore uses. |
| Progress |
This project is an extension of research completed by the Colorado School of
Mines in December 2005 on the assessment of magnetism effects on hydrogen
cracking for thick walled pipelines (see Project No. 487). That
project found that under
laboratory conditions, high-strength steel was susceptible to corrosion and
hydrogen cracking at hydrogen saturation levels under magnetism. Project 522 develops the methodology for field testing equipment that can determine a pipeline's susceptibility to hydrogen cracking depending on the level of hydrogen content. The final report regarding the studies scope of work and findings is located in the Reports section below for viewing and/or downloading. |
