• Effect of long periods of corrosion on the fatigue lifetime of offshore mooring chain steel 

      Qvale, Paul; Nordhagen, Håkon Ottar; Ås, Sigmund Kyrre; Skallerud, Bjørn Helge (Peer reviewed; Journal article, 2022)
      R4-grade mooring chain steel specimens were subjected to alternating phases of saltwater corrosion and air fatigue to replicate seasonal load variations on chains in service. No significant difference in fatigue lifetimes ...
    • 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 ...
    • Low-velocity impact behaviour and failure of stiffened steel plates 

      Gruben, Gaute; Sølvernes, S; Berstad, Torodd; Morin, David; Hopperstad, Odd Sture; Langseth, Magnus (Peer reviewed; Journal article, 2017)
      The behaviour and failure of stiffened steel plates subjected to transverse loading by an indenter is studied in this paper. Low-velocity dynamic and quasi-static tests of stiffened plates with geometry adopted from a ...
