Wall Thickness Fabrication Tolerance Type tfu: Proceedings of an International Conference Submersible Technology: Proceedings of an international conference Diverless and Deepwater Techology: In this paper the development of the RP is outlined, the determination of the safety factors are explained and the sensitivity of the safety level to the various parameters is demonstrated.
Pipe Outside Circumference OD: The development of the capacity equations and acceptance equations giving the allowable operating pressure and the development of the safety factors are described in this paper.
Cnv first approach includes calibrated safety factors, taking into account the natural spread in material properties and wall thickness and internal pressure variations. Wall Thickness Schedule Type tnu: RP-F describes two alternative approaches with different safety philosophy.

The second approach is based on the allowable stress design format, where the allowable operating pressure is determined from the capacity and multiplied with a single usage factor based on the original design factor.
RP-F includes recommendations for the assessment of: Uncertainties associated with f110 sizing of the defect and the specification of the material properties are specifically considered in determination of the allowable operating pressure.
