Publication Date: 1 September 2019

scope:

This RP is assumed to be used together with other DNV GL offshore standards (OS) or NORSOK N standards as listed in /1/ to /6/ or other recognised standards. It is assumed that this RP will be used together with DNVGL-RP-C203 Fatigue design of offshore structures. This RP is intended to give sufficient guidance to the user on how to establish a sound basis for probabilistic in service inspection planning for fatigue cracks. This basis should as a minimum include advice on:

- Fatigue analysis methods for jacket structures, semi-submersibles and floating production vessels (FPSOs).

- Effect of methodology/refinement used in fatigue analysis with respect to calculated fatigue life.

- Basic distributions of parameters required for calculation of stochastic properties for load effects and capacity.

- Derivation of target reliability level in relation to consequence of a fatigue failure.

- Methodology for probabilistic analyses for planning inspection for fatigue cracks. Required theory to explain the methodology should be provided in order that users of the document can easier understand the use of the standard and significance of input parameters to the analysis.

The document may be used for planning inspection for fatigue cracks in new built and existing structures and also for analysis of lifetime extension of platforms.
