Our first pipeline code was issued in 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. With the updates, the standard now gives requirements to when an Engineering Critical Assessment should be performed.

Removing the requirement to fill the empty pipeline with water can significantly reduce cost for pipeline operators, according to a DNV GL statement, although some additional work will be required to prove an equivalent safety f11. Pressure Welding Underwater pipelines Stress.

ECAs are, necessarily, conducted towards the end of the design process, at which point the design loads have been defined, the welding procedures qualified and the material properties quantified. Controlled lateral buckling in offshore pipelines typically gives rise to the combination of internal over-pressure and high longitudinal strains possibly exceeding 0.

For example, the outcome of a workshop on dimensions including key industry players has now been built into the standard. About us Contact us Help Terms of use. The combination of internal over-pressure and longitudinal strain appears to become more complicated as the longitudinal strain increases, because of the effect of bi-axial loading on the stress-strain response. In this context, ECAs and FE are not an ideal combination for the pipeline operator, the designer or the installation contractor.

DNV-OS-F101 pipeline standard gets update from DNV GL

V05BT04A; 15 pages doi: It is shown that an assessment based Option 2, which does not require FE analysis, can potentially give comparable results to the more detailed assessments, when more accurate stress intensity factor and reference stress plastic limit load solutions are used.

It recommends a crack driving force assessment, rather than one based on the failure assessment diagram. A pipeline subject to internal over-pressure is in a state of bi-axial loading.

The standard now reflects findings on selection of safety classes, limit state criteria, additional guidelines specific to PiP and code breaks. Based on our project experience, research and joint industry development work, DNV GL issues a number of pipeline codes.
