• Buckling capacity of simulated patch corroded tubular columns – laboratory tests 

      Vo, Tri Minh; Hestholm, Kristoffer; Ersdal, Gerhard; Oma, Narve; Sivertsvik, Matias (Peer reviewed; Journal article, 2019)
      This paper presents the experimental test results for the buckling capacity of tubular columns exposed to simulated unsymmetrical patch corrosion damage. These tests were performed to investigate how the results of these ...
    • Inspection planning for fatigue cracks in offshore structures by Monte Carlo simulations 

      Neeraas, Håkon; Ersdal, Gerhard; Oma, Narve; Hellevig, Nils-Christian (Peer reviewed; Journal article, 2019)
      Probability-informed inspection planning has traditionally a tendency to produce longer inspection intervals for older structures in contrast with the intuitive assumption that shorter inspection intervals are needed. In ...
    • Investigation of updating methods for probability-informed inspection planning for offshore structures 

      Ersdal, Gerhard; Oma, Narve (Peer reviewed; Journal article, 2019)
      The paper presents a novel process for probability-informed inspection planning based on the following principles. 1) A description of the strength of knowledge about a problem shall be included and be accounted for in the ...
    • Life extension of ship-shaped floating production units 

      Schøn, Iselin Violet Kjelland (Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-06)
      In the last two decades, the number of floating, production, storage, and offloading units (FPSOs) deployed internationally has increased rapidly. Many of them are still young but have already started ageing. The objective ...
