Characterization of annulus well cement quality to estimate the leakage potential in cement well barriers
(PhD Theses;676, Doctoral thesis, 2022-11)Cement is nowadays the most used material that is placed inside of wells as a barrier element to ensure zonal isolation and avoid migration of fluids between the reservoir and surface. Sometimes the well integrity can be ... -
A Critical Look at the Evaluation of Knowledge Graph Question Answering
(PhD thesis UiS;, Doctoral thesis, 2022-11)The field of information retrieval (IR) is concerned with systems that “make a given stored collection of information items available to a user population” [111]. The way in which information is made available to the user ... -
En casestudie: Utfordringer med å implementere Lean Startup, Design Thinking og Scrum
(Master thesis, 2022)Motivasjon: Lean Startup, Design Thinking og Scrum er tre metoder med økt bruk i programvareutviklingsprosjekter. Selv om de er velkjente metoder, er det risiko for å støte på problemer når de implementeres. For å lære mer ... -
Bridge aerodynamics in skew winds: Generalized buffeting load modelling and response analysis
(PhD thesis UiS;, Doctoral thesis, 2022-11)This thesis deals with the modelling of wind loads on bridges. When turbulent wind blows past a bridge deck, the deck experiences fluctuating loads, i.e., buffeting loads. Most buffeting theories concern straight bridge ... -
Classifying Complexity in Oil and Gas Brownfield Projects
(Master thesis, 2022)It is widely recognized that research regarding complexity in projects has been inspired by Baccarini through his publication in 1996. Since then, research on this topic has been developing to other areas such as healthcare, ... -
Prediction, interpolation and extrapolation of drilling data with Deep Learning
(Doctoral thesis, 2022-11)Directional drilling is an established technology within the petroleum industry. In this traditionally conservative and risk averse environment application of artificial intelligence encounters difficulties at various ... -
Power Performance and Response Analysis of a Semi-Submersible Wind Turbine Combined with Wave Energy Converters in Intermediate and Deep Water
(Master thesis, 2022)Renewable energies are the forefront against environmental pollution and the leading technology in sustainable energy sources. Power produced by wind energy is a well established technology. There is a lot of space for ... -
Risk Assessment of Utilising an Extra-Large Autonomous Underwater Vehicle for Liquid CO2 Transportation
(Master thesis, 2022)The development of autonomous maritime systems has been proliferating in recent years. One of these systems is a subsea shuttle tanker (SST) concept proposed as a potential alternative to pipelines and tanker ships for ... -
Smart Building Data Collection and Ventilation System Energy Prediction
(Master thesis, 2022)Data has the potential to transform our environments for the better if utilized to its full potential. A highly interesting use case of data is in relation to Smart Buildings, where IoT technology presents new possibilities. ... -
Understanding the Barriers to Reuse: A Qualitative Study of Reuse Potential in the Norwegian EE Industry
(Master thesis, 2022)The rapid growth in consumption and use of electronics has resulted in E-waste becoming one of the most accelerated global waste streams. Despite high rates of electrical and electronic (EE) recycling, Norway is one of the ... -
A study on ship-bridge collisions and the significance of the collision energy and impact angle for the probability of collapse
(Master thesis, 2022)Bridges are a necessity for transportation across waterways in modern society, and the passing of large ships below bridges poses the risk of ship-bridge collision, which can, in the worst case, lead to the total collapse ... -
