V05BT04A; 15 pages doi: Yes, provided that the essential variables and restrictions on use of previously qualified procedures are not transgressed. These comprise service specifications, standards and recommended practices, and are highly regarded within the international pipeline community. For example, the outcome of a workshop on dimensions including key industry players has now been built into the standard.


A pipeline subject to internal over-pressure is in a state of bi-axial loading. The revision also takes into account the findings from two joint industry projects run outside DNV GL: The joint industry projects presented the typical challenges that should be addressed in planning and design of marine operations and the common basis for installation design of pipelines, umbilicals and cables.

After the publication it has been used throughout the world with an acceptance that has far exceeded DNV”s expectations. For assistance or to subscribe, please contact us: The Rules have now been in extensive use for two years and considerable experience has been gained.
