This standard, based on limit state design principles, are presented on the LRFD Load and Resistance Factor Design format, allowing different riser design alternatives to take into account the environmental conditions.

Volume 1, Parts A and B: This analysis excludes the terms associated with accidental loads. For assistance or to subscribe, please contact us:. It should be mentioned that the structural design criteria, traditionally employed for such risers under extreme and operational conditions, were based on the API-RP-2RD.
Under DNV OS Faccidental loads are not usually considered simultaneously with functional and environmental loads in global analyses.
In order to calculate the results, derived values for burst resistance pressure and collapse pressure are required.
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. These are implemented in OrcaFlex as separate results. These are oos as follows.
It operates independently of a user’s location or IP address. Related Content Customize your page view by dragging and repositioning the boxes below.
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.
To allow the environmental load to be separated from the function load, you must nominate a functional load case.

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.
This design criterion makes use of single safety factor on von Mises stress. oss

Even if you have specified, separately, the line type Young’s modulusyou must also supply a non-zero value here. The modulus of elasticity. The loads can then be separated:. This means that a different combination of factors might be used for the tension and the moment. It is not, however, included explicitly in the DNV equations.
