摘要

Abstract In 2002, several mooring chains of a deepwater offloading buoy failed prematurely within a very small time frame. These chains were designed according to conventional offshore fatigue assessment using API recommendations. With this first deepwater buoy application, a new mooring chain fatigue mechanism was discovered. High pretension levels combined with significant mooring chain motions caused interlink rotations that generated significant Out of Plane Bending (OPB) fatigue loading. Traditionally, interlink rotations are relatively harmless and generates low bending stresses in the chain links. The intimate mating contact that occurs during the proof loading and the high pretension of the more contemporary mooring designs have been identified as aggravating factors for this phenomenon. A Joint Industry Project (JIP), gathering 28 different companies, was started in 2007 to better understand the OPB mooring chain fatigue mechanism and propose some mooring chain fatigue design recommendations. This paper summarizes the various test programs that were implemented within the more than 6 years long project, including full scale fatigue tests on chains, a quasi static OPB stiffness measurement campaign, and tests on small samples addressing the environmental parameter influence on fatigue initiation and crack propagation stages. The main output from the FEA scope of work, performed to support the experimental tests, will also be described. Finally, the paper will address the major step that has been achieved regarding implementation of a standard practice in offshore industry using a multiaxial fatigue criterion to address OPB hotspots.
