    • Experimental evaluation of the axial capacity of cracked tubular member 

      Riise, Simen (Bachelor thesis, 2021)
      This thesis experimentally investigated the compressive axial capacity of cracked tubular members. Then compared it to NORSOK N-004 (Standard Norge 2004) formulae. Further, the test results were compared with other analytical ...

    • 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 ...

    • Momentkapasitet av slakkarmerte og spennarmerte betongkonstruksjoner med korrosjonsskader 

      Sigvaldsen, Marie (Master thesis, 2021)
      I Norge finnes en rekke kystnære bruer med varierende grad av korrosjon. I kapasitetsberegninger av disse eldre konstruksjonene er normalt bare prosentvis reduksjon av bærekapasiteten tilsvarende prosentvis korrosjonstap ...

    • Remaining capacity of deteriorated I-section structural steel members 

      Yared, Ermias (Masteroppgave/UIS-TN-IMBM/2018;, Master thesis, 2018-06)
      Abstract Steel have many design and functional advantages as a material in the construction process and in structures in use. However, deterioration of steel e.g. due to corrosion is one of the drawbacks for steel ...

    • Sprekkvekst og inspeksjonsplanlegging 

      Neraas, Håkon (Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019)
      Hensikten med denne oppgaven er å undersøke behovet for inspeksjoner for å oppdage sprekkvekst i et kritisk knutepunkt på en offshore jacket underlagt syklisk bølgebelastning. Det er studert hvor ofte det er nødvendig med ...

    • Statistical evaluation of fatigue lives of offshore tubular joints. 

      Alvarez, Alejandro (Master thesis, 2021)
      Fatigue design in offshore structures is based on S-N curves derived from tests on tubular joints where failure is defined as penetration of wall thickness. However, in practice, fatigue cracks are likely to continue to ...

    • Structural reliability and optimal design of fixed jacket of offshore wind turbine 

      Alalawi, Hamad (Master thesis, 2021)
      The assessment of structural reliability for offshore wind turbines (OWTs) is challenging. The environmental conditions and loads on a wind turbine have large variability. Wind and wave act simultaneously on the structures, ...
