Analysis of S–N data for new and corroded mooring chains at varying mean load levels using a hierarchical linear model
Lone, Erling Neerland; Maincon, Philippe Emmanuel; Gabrielsen, Øystein; Sauder, Thomas Michel; Larsen, Kjell; Leira, Bernt Johan (Journal article; Peer reviewed, 2023)Results from full scale fatigue tests of offshore mooring chains are analyzed. The data set includes new and used chains, tested at a variety of mean load levels. The used chains have been retrieved after operation offshore ... -
Estimation of top tensions in mooring lines by sensor fusion
Sauder, Thomas Michel; Maincon, Philippe Emmanuel; Lone, Erling Neerland; Leira, Bernt Johan (Peer reviewed; Journal article, 2022)The paper describes a sensor fusion method that provides reliable, uninterrupted and bias-free estimates of the top tension in a mooring line. The method exploits the geometric nonlinearity of mooring systems installed in ... -
Fatigue reliability of mooring chains, including mean load and corrosion effects
Lone, Erling Neerland; Sauder, Thomas Michel; Larsen, Kjell; Leira, Bernt Johan (Peer reviewed; Journal article, 2022)A reliability formulation for mooring chain fatigue is developed, including the effects of mean load and degradation due to corrosion. They are included by starting from a S-N model with parameterized dependence to the ... -
Probabilistic fatigue model for design and life extension of mooring chains, including mean load and corrosion effects
Lone, Erling Neerland; Sauder, Thomas Michel; Larsen, Kjell; Leira, Bernt Johan (Peer reviewed; Journal article, 2022)A probabilistic model for mooring chain fatigue damage is developed based on the S–N approach. The effects of mean load and corrosion condition on the fatigue capacity of the chains are included by adopting a parameterized ...
