The main objective of this document is to provide rational design criteria and guidance for assessment of pipeline on-bottom stability subjected to wave and. The recommended guideline DNV RP F, “On-bottom stability of assessment of submarine pipelines” and American Gas Association/Pipeline Research. Hello you guys, I would like to know what are the differences between the two recommanded practices of DNV: DNV RP E and DNV RP.
