Investigations Into Break Strength of Offshore Mooring Chains

Offshore Technology Conference, 2017
Abstract The first phase of the Chain FEARS (Finite Element Analysis of Residual Strength) Joint Industry Project (JIP) aimed to develop guidance for the determination of a rational discard criteria for mooring chains subject to severe pitting corrosion which, based on current code requirements, would otherwise require immediate removal ...

The Character of Hydrogen Embrittlement in Mooring Chain Steel

JOM, 2020
The digital image correlation method has been applied to directly observe the local strain and crack formation in mooring chain steel during tensile tests in air or when simultaneously charging hydrogen in different ways, viz. including/excluding the notch root.

Probabilistic Chain Cable Strength and Mooring Reliability

Offshore Technology Conference, 1992
ABCTRACT Based on the strength distribution of individual links, a chain cable strength model which conforms to an asymptotic extreme value distribution is formulated. The subject of probablistic chain breaking strength is investigated and it is found that the variability of link strength is of crucial importance ...

Unexpected Rapid Corrosion in Mooring Chains Explained

Offshore Technology Conference Asia
Abstract High rates of corrosion had led to severe material loss in a low-alloy medium carbon steel Tether Chain from an offshore mooring system after only 5 years in service. The material losses were caused by extensive corrosion pitting and wear damage from adjacent links.
