DYNAMIC ARREST OF PROPAGATING BUCKLES IN OFFSHORE PIPELINES

摘要

Buckle arrestors are devices which locally strengthen an offshore pipeline and safeguard it against the catastrophic effects of a potential propagating buckle. They are usually designed based on quasi-static experiments and analyses. This paper discusses how such devices perform under the more realistic dynamic propagation conditions encountered in the sea. It will be shown that dynamics enhance the arresting performance of all arrestors considered.
