Specified Minimum Yield Stress for Flexible Pipe.
Specified Minimum Yield Stress for Flexible Pipe.
(OP)
Hi everyone.
Im 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.
Thank you.

RE: Specified Minimum Yield Stress for Flexible Pipe.
However flexibles work in a different way to rigid steel pipes and so I think you're in danger of using incorrect data.
Flexibles are, well, flexible, and hence tend to move when subjected to force and loads such as trawl boards.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

I'm also not confident with my method, but need to start somewhere at least.
Have a great day.
