A new method allows for determination of axial force on subsea pipelines within the context of DNV(Det Norske Veritas)-RP-F105-2006, expanding the scope of current recommended practices and benefiting both project economics and safety. Existing recommended practices for free span analysis do not address how to determine axial force in subsea pipelines, except for theoretical simplified conditions of axially completely unrestrained or totally restrained pipe. As a result the designer often uses the totally restrained value to be conservative. Seabed unevenness, change of seabed topology, strudel scours, and artificial supports required for existing pipeline crossings can all lead to free spans in subsea pipelines. Assessment of free span requires structural (static) analysis. This article provides guidance within the development of DNV RP-F105 -2006 for assessment of pipeline free spans based on design criteria.
