(Masteroppgave/UIS-TN-IKM/2017;, Master thesis, 2017-12-15)Reports from the Gulf of Mexico (GoM) show that thousands of wells exhibit sustained casing pressure (SCP), however the extent of this phenomena and its driving factors have yet to be studied in detail on the Norwegian ... -
Investigation of the corrosion properties of 316L in marine atmosphere and assessment of the effectiveness of different surface repassivation products
(Masteroppgave/UIS-TN-IMBM/2018;, Master thesis, 2018)The major purpose of this thesis was to investigate and assess what effect of repassivation product has on corrosion resistance of 316L in marine atmosphere. Additionally, compare the chemical composition with the certificate. ... -
An investigation of the effects and consequences of combining Expanding Dual Pin with radial spherical plain bearings
(Peer reviewed; Journal article, 2022)An expanding pin locks the pin assembly to its supports and bearings and prevents any relative movements between the surfaces in contact. In this study, the diameter changes of the bearing inner ring as a function of the ... -
Investigation of the mechanical properties of Acacia tortilis fiber reinforced natural composite
(Peer reviewed; Journal article, 2020-10)The work presented in this paper is motivated by the fact that use of natural fiber materials for structural and non-structural applications have increased within the last two decades. In addition to the known benefits of ... -
Investigation of transitional turbulence models for CFD simulation of the drag crisis for flow over a sphere
(Peer reviewed; Journal article, 2019)The drag crisis is an interesting physical phenomenon for flow over bluff bodies, where the drag coefficient suddenly drops as the Reynolds number increases. This behavior is caused by the flow transitioning from laminar ... -
Investigation of transitional turbulence models to predict drag crisis for flow over spheres and cylinder
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-14)The current work performed experimental and numerical studies of flow over cylinders and spheres. The purpose is to investigate whether the drag crisis phenomenon can be predicted, and to gain insight into the transition ... -
Investigation of updating methods for probability-informed inspection planning for offshore structures
(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 ... -
Investigation of which sea state yield the dominating contribution to fatigue accumulation in offshore structures
(Masteroppgave/UIS-HF-IKM 2014;, Master thesis, 2014-06-23)Majority of the fatigue damage on offshore structures is generally assumed to be caused by relatively frequently occurring moderate sea states, i.e. sea states with significant wave height in the range of 4m - 8m.On the ... -
Investigation on The Mechanical Properties of CO2 Cured Concrete with Natural Aggregates.
(Bachelor thesis, 2021)Betongproduksjon er en av industriene med størst CO2 utslipp i verden. En liten reduksjon i CO2 utslippene fra denne industrien kan derfor være svært gunstig for å nå klimamålene. Herding ved akselerert karbonatisering ... -
