Flexible pipelines and risers have been in use on Norwegian oil and gas installations for more than 20 years. These are complex systems with many different failure modes. Analysing failures and incidents relating to production, installation and operation has enhanced the reliability of such facilities and increased knowledge about them.
A number of new pipelines and risers have been installed in recent years. One of the focal areas for the PSA’s supervisory work is ageing and life-time extension, which also includes flexible pipeline technology and the evaluation of degradation mechanisms. During 2006 and 2007, the PSA has held meetings with operators and contractors to acquire an overview of what is known about flexible pipelines and risers.
The seminar is intended to increase the general level of such knowledge and to transfer experience within the industry. Its principal focus will be on experience, failure modes and mechanisms, systemising and use of inspection data, development of inspection and monitoring techniques, and incidents.
