Spectrum-Span and Fatigue
This module calculates allowable span lengths in accordance with DNVGL-RP-F105. The module will perform L1, L2 and L3 assessment for high cycle VIV loading. Allowable freespan length is calculated for In-Line, Cross-Flow and static stress. For a given span length, fatigue life is calculated.
Fatigue damage/fatigue life is also calculated for low cycle fatigue conditions such as Operational cyclic Loading, Slugging, Flow Induced Vibration (FIV) and Flow Induced Pulsation (FIP).
