This sheet is created to automate the formulations used by DNVGL-RP-F105 for a pipeline free span assessment.
The sheet provides the assessments of Vortex Induced Vibration and Fatigue Check
Multiple tables and formulations are simultaneously solved to arrive at the conclusions in-line with DNVGL-RP-F105 . The sheet maybe utilized at the Tender stage to identify the nature of free-spans resulting from pipe-lay and take into account mitigation measures for the free-span beforehand.
The current sheet is a COMPACT version. This means:
- The sheet provides the assessments of Vortex Induced Vibration and Fatigue Check
- The sheet takes into account the free-span frequency analysed by modal analysis performed in other tools like OrcaFlex, OFFpipe other other tools.
