Interacting Defect Minimum Overlap Length 2. Calculate pipeline defect interaction length and interaction angle, and projection line minimum length, minimum overlap and projection line angular spacing DNVGL-RP-F section 3. Rock Mechanics Symposium and 5th U. 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. Proceedings of an International Conference Submersible Technology: Diameter Over Wall Thickness Ratio tf: 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. 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.
