In the spreadsheet, for load interaction, I need to put the value of ME (Maximum Bending Moment due to Environmental load). I am doing wall thickness calculation based on DNV-OS-F-101. So my question is how can i get Bending Moment if I know SMYS because SMYS is a stress with units in MPa and Bending Moment units is in Kilo Newton Metre. I have read in a technical document, that for initial calculation Max Bending Moment can be estimated as 0.85 times SMYS. Is it possible to determine or some more information is necessary? I don’t know in which category this would come. I would like to know bending moment for subsea pipeline as well as the riser. It is a 6" subsea pipeline between Well Head Platform and Production Platform with risers installed at both ends. I am not too sure exactly about the conditions. I just want to know what is the formula for maximum bending moment for a steel pipe? I have forgotten Strength of Material Basics that I studied in 1st Yr. I am sorry for asking such a fundamental question.
