Mooring Line Failure Detection in the Absence of Load Monitoring
Volume 1: Offshore Technology, 2022Abstract Mooring Integrity Management (MIM) is a key operational aspect for FPSO operators, mooring system designers and Recognized Classification Societies (RCS). MIM programs should include the capability to detect a mooring line failure.

Numerical Investigation on the Mooring Line Failures of a Semi-Submersible Platform
Journal of Offshore Mechanics and Arctic Engineering, 2023Abstract Numerical simulations on the mooring line failures of a semi-submersible platform under the extreme ocean environment are performed. The single mooring line and double mooring line failures, as well as the subsequent progressive failure process of multiple mooring lines, are investigated.

Effects of one mooring line failure on the behaviour of a work ship
Proceedings of the Institution of Civil Engineers - Maritime Engineering, 2022The dynamic performance of a work ship with a mooring line failure was studied. A fully coupled dynamic analysis program (Ansys Aqwa) was applied to simulate ship motions and mooring line dynamics. The first- and second-order wave excitation forces were calculated using the three-dimensional diffraction/radiation theory, and the behaviours of the ...

FPSO Mooring Line Failure Detection Based on Predicted Motion
Volume 1: Offshore Technology, 2021Abstract A failure in the mooring line of a platform, if not detected quickly, can cause a riser system failure, extended production downtime, or even environmental damages. Therefore, integrity management and timely detection of mooring failure for floating platforms are critical.

Sensitivity Analysis of an ANN-Based System for Detection of Mooring Line Failure
Volume 1: Offshore Technology, 2020Abstract Monitoring the integrity of mooring lines on floating offshore platforms is one of the key factors in ensuring safe and productive offshore operations. Sensors, such as inclinometers, compressive load cells or strain sensors, can be used to monitor the inclination angles or tensions on mooring lines.

Mooring Line Failure Detection Using Machine Learning
Offshore Technology Conference, 2019Offshore floating vessel mooring failure and subsequent loss of station can have catastrophic consequences for the vessel and the associated subsea infrastructure. Therefore, integrity management and timely detection of mooring failure is critical.

Failure Probability Analysis Techniques for Long Mooring Lines
Offshore Technology Conference, 1992ABSTRACT This paper describes statistical techniques for analyzing failure probabilities of long mooring lines. The long line is treated as a series of segments, each as long as the break or fatigue test specimens. Termination failure statistics are treated separately.

Progressive Mooring-Line Failure of a Deepwater MODU in Hurricane Conditions
Volume 1: Offshore Technology, 2009During 2004–2005, three consecutive category-5 storms hit the central region of Gulf of Mexico (GOM) and damaged numerous drilling and production platforms. Since then, a number of forensic studies have been conducted to better understand the failure causes and mechanism.

Hydrodynamic Behaviors of Aquaculture Net Cages After the Successive Mooring Lines Failure
Volume 5: Ocean Space Utilization, 2021Abstract This paper aims to study the successive mooring line failure (also known as the domino effect) and the collision between floating collars for aquaculture net cages subjected to currents. The numerical model of this study is developed based on the Morison equation and the lumped-mass scheme in the time domain.
