I'm junior engineer and has been assigned to do trawl-pipeline interaction.
My main reference is DNV-RP-F111, and i got stuck how to find plastic moment capacity (mp) which required me to get the value of specified minimum yield stress (SYMS). Since the pipeline is flexible type, I dont have enough data/ source to refer.
Since I have the value for axial stiffness (in tension),(this data usually provided in FEED stage for stiffness of pipeline) i used it to calculate the stress, which stress=Force/cross sectional area, the value will be my basis for the study.
Really appreciate everyone thought/ guidance on this.
