In this paper the development of the RP is outlined, the determination of the safety factors are explained and the sensitivity r101 the safety level to the various parameters is demonstrated.
RP-F includes recommendations for the assessment of: RP-F describes two alternative approaches with different safety philosophy.
The first approach includes calibrated safety factors, taking into account the natural spread in material properties and wall thickness and internal pressure variations. Uncertainties associated with the sizing of the defect and the specification of the material properties are specifically considered in determination of the allowable operating pressure.
Background And Development of DNV-RP-F "Corroded Pipelines" – OnePetro
The second approach is based on the allowable stress design format, where f110 allowable operating pressure is determined from the capacity and multiplied with a single usage factor based on the original design factor. 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.
The results from their respective joint industry projects have been merged and form the technical basis for RP-F Several oil companies and regulating authorities have sponsored the development of the RP.
The steps in the development and the background for the methods are described in this paper. About us Contact us Help Terms ep use. Publishers Content Coverage Privacy. Sheriff’s Encyclopedic Dictionary of Applied Geophysics, fourth edition.
