Out-of-Plane Bending (OPB) fatigue of mooring chains was first identified as a failure mechanism after the failure of several mooring chains of a deep water offloading buoy in 2002. The discovery of this failure mechanism resulted in a Joint Industry Project (JIP) that ran from 2007 to 2013 and provided valuable insights as well as a design methodology. …

OPB fatigue uses the inter-link angular rotation converted to a stress (under constant chain tension) as a source of fatigue. Figure 1 shows the failure of a 81mm mooring chain in OPB.
This paper proposes an efficient approach based on a machine learning technique to predict the local stresses on mooring chain links. Three-link and multi-link finite element analyses were ...
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 …

The mooring system is essential for floating structures withstanding harsh environmental conditions, such as corrosion and variant wave loads. Failures of mooring systems has attracted researchers in different fields related to on-shore and off-shore activities. In this work, a study is conducted on a failed chain by conventional metallurgical failure …
The chain OPB (out of plane bending)/IPB (in plane bending)-induced fatigue drew industry's attention after the report of Girasol SPMB (singlepoint-mooring-buoy) chain-mooring failure in 2002 [1].

Abstract. Chevron Corporation and Bluewater Energy Services (BES) performed a chain out-of-plane bending (OPB) test, called OPB MAX hereafter, at DNV GL's laboratory in Høvik-Norway. The test was performed to study the OPB phenomenon for a chain diameter which was larger than the maximum diameter tested by the OPB JIP. The goal was to …
