• 3D Scanning of Corroded Mooring Chain 

      Hoel, Alexander (Master thesis, 2016)
      This thesis is concerned with mooring line failure and 3D representations of corroded chain surfaces. Equipment for making such representations have been evaluated through a feasibility study carried out at NTNU. An ATOS ...
    • Analysis of fatigue test data of retrieved mooring chain links subject to pitting corrosion 

      Mendoza Espinosa, Jorge; Haagensen, Per Jahn; Kohler, Jochen (Peer reviewed; Journal article, 2021)
      Fatigue is one of the main failure mechanisms of catenary type mooring lines. Fatigue resistance is affected by a large number of factors. In this paper, the effect of pitting corrosion on the fatigue resistance of mooring ...
    • Chains in Mooring Systems 

      Bjørnsen, Evy (Master thesis, 2014)
      Mooring systems of floating structures consist of long lengths of chain, rope or wire, or a combination of these elements. As part of a station-keeping system, the mooring lines have to keep the movements of the structure ...
    • Degradation Mechanisms of Chain Links in Offshore Mooring Lines 

      Tømmervåg, Kristin Hanem (Master thesis, 2016)
      Degradation mechanisms contributing to mooring line failures are identified and discussed with respect to the service conditions for the defined mooring line segments. Corrosion, environmental assisted cracking (EAC) and ...
    • Growth of Fatigue Cracks in Mooring Line Chains 

      Hove, Martin (Master thesis, 2016)
      This master thesis is the continuation of a project work conducted during the fall of 2015, and is part of a series of studies investigating the effect of surface condition on the fatigue life of mooring chains. The study ...
    • Multiaxial fatigue analysis of offshore mooring chains, considering the effects of residual stresses and corrosion pits 

      Zarandi, Ershad P. (Doctoral theses at NTNU;2020:337, Doctoral thesis, 2020)
      The integrity of the mooring lines used to anchor offshore facilities and floating platforms has been always desired while its continuous achievement has been challenging. Many mooring line failures have occurred in the ...
    • Numerical Investigation of 3D Scanned Mooring Chains - Effects of Stress Concentrations from Corrosion Pits 

      Bache, Truls Johan Martin Braut (Master thesis, 2017)
      This thesis aims to numerically evaluate severe corrosion pits on offshore mooring chain. Pitting corrosion is considered a significant degradation mechanism as cracks tend to nucleate and propagate in areas of high stress ...
