    • 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 (Peer reviewed; Journal article, 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 ...

    • Fatigue crack growth in mooring chain steel at different mean load levels 

      Hellum, Vidar; Gabrielsen, Øystein; Ås, Sigmund Kyrre (Peer reviewed; Journal article, 2023)
      The fatigue crack growth rates of R4 mooring chain steel at different R-ratios are investigated. Crack growth experiments are performed at three different R-ratios, 0.1, 0.3 and 0.7, utilizing compact tension specimens in ...

    • Influence of Mean Tension on Mooring Line Fatigue Life 

      Lone, Erling Neerland; Leira, Bernt Johan; Sauder, Thomas Michel; Aksnes, Vegard Øgård; Gabrielsen, Øystein; Larsen, Kjell (Chapter, 2020)
      Studies published in recent years have documented a significant mean load effect on fatigue capacity for offshore mooring chain, and show that a reduction of the mean load gives an increase in fatigue life. However, current ...
