Summary
General
DNVGL has issued a number of guidelines for fatigue assessment of floating platforms. These documents include information that is related to:
• modeling environmental loading and response;
• modeling principles for analysis models of FPSO (floating production, storage, and offloading vessels);
• hydrodynamic analysis methodology;
• fatigue analysis methodology;
• documentation and verification of analysis methodology.
Semi-Submersibles
Guidelines for fatigue design of semi-submersibles are presented in DNV-OS-C103 (2014).
Guidelines on fatigue analysis for planning in-service inspection for fatigue cracks of semi-submersibles can be found in appendix B of DNVGL-RP-0001 (2015).
Floating Production Vessels (FPSOs)
Guidelines on how to perform a global and local fatigue analysis of a typical FPSO, with both turret-moored and fixed spreader-moored arrangements, can be found in DNV-RP-C206 (2012).
Guidelines on fatigue analysis of FPSOs for planning in-service inspection for fatigue cracks can be found in appendix C of DNVGL-RP-0001 (2015). The referred documents can be downloaded from the DNV GL web page for free. This is one reason for making this section short.
