Defines an alternative, smaller functional load factor to satisfy the requirement DNV OS Ftable that, if the functional load effect reduces the combined load effect, a smaller functional load factor shall be used.

It should be mentioned that the structural design dnb, traditionally employed for such risers under extreme and operational conditions, were based on the API-RP-2RD. These are calculated as cnv. Note that the DNV OS F LRFD result, when the model is in the static state and the functional load is specified by the current model, will therefore have no environmental load contribution.

This means that a different combination of factors might be used for the tension and the moment. A value other than the default will be applied at all arc lengths which use this line type. DNV OS Fsection 5, D states that, if the bending moment can be assumed secondary, the bending moment used in the code checks may be multiplied by a condition factor. Volume 1, Parts A and B: Even if you have specified, separately, the line type Young’s modulusyou must also supply a non-zero value here.
