DOI: 10.1016/j.oceaneng.2019.106752
Abstract: Abstract Initial imperfections (out of straightness) constitute one of the key parameters impacting lateral buckling of pipelines as they influence both pre-buckling assessment and pipeline integrity assessment during the post-buckling stage. When adjacent imperfections exist… read more here.
