Investigation on Offshore Floating Mooring Chains Failure

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 …

Guidance for Assessing Out-of-Plane Bending Fatigue on Chain …

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. …

Chain Out of Plane Bending (OPB) Fatigue Joint Industry Project (JIP

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 …

Out-of-Plane Bending (OPB) Test of Large Diameter …

Abstract. Chevron Corporation and Bluewater Energy Services performed a chain out-of-plane bending (OPB) test campaign, called OPB MAX hereafter, at DNV'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 [12]. The goal was …
