Analysis of Factors Contributing to Long Term Shallow Gas Migration to Seabed in Surface Casing Annulus
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-07)A common observation is a low rate gas bubbling from the outside of the 20” surface casing on wells located in the Haltenbanken area on Norwegian Continental Shore. This phenomenon is known as long term shallow gas migration ... -
Analysis of field measurement data from the Lysefjord bridge in relation to main cables wire fracture
(Master thesis, 2022)A 637-meter suspension bridge located in Rogaland county, Norway, which connects the two municipalities of Strand and Sandnes, is known as the Lysefjord Bridge. The bridge is located in Rogaland county, and the bridge ... -
Analysis of filtering techniques for investigating landslide-induced topographic changes in the Oetz Valley (Tyrol, Austria)
(Peer reviewed; Journal article, 2020)Landslides endanger settlements and infrastructure in mountain areas across the world. Monitoring of landslides is therefore essential in order to understand and possibly predict their behavior and potential danger. ... -
Analysis of flame propagation using an imaging technique BOS (Background Oriented Schlieren) and PIV (Particle Imaging Velocimetry).
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06)An experimental and simulation work has been conducted to study premixed flame propagation using imaging technique BOS (background oriented schlieren) and PIV (particle imaging velocimetry). Flame images obtained from ... -
Analysis of forces in a subsea wellhead system supported by NeoDrill conductor anchor node
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)During drilling operations the marine drilling riser is exposed to environmental loads like waves and currents, as well as loads from the rig. These environmental loads are transferred from the riser to the wellhead system. ... -
Analysis of Gas Hydrate Growth Models
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-28)The kinetic behaviour of gas hydrate formation of pure methane have been studied and predicted based on different models. Experiments have been conducted at different temperatures and stirring rate, and the measured results ... -
Analysis of global forces in the wellhead/wellhead connector as a function of wellhead lateral support and stiffness
(Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2014-06-16)During the life of a well (typically 20 years), a number of operations need to be performed that requires the wellhead/wellhead connector to connect directly to a rig through a riser system. While connected to the vessel ... -
Analysis of Greenhouse Gas Emissions from Offshore Wind Turbines
(Master thesis, 2022)Renewable energy resources such as offshore wind turbines are considered as if they do not emit greenhouse gas emissions, as greenhouse gases are not emitted from these resources during electricity generation. However, ... -
Analysis of how the political parties Miljøpartiet De Grønne and Fremskrittspartiet use risk concepts regarding climate change
(Master thesis, 2023)Climate change is one of the biggest issues we are facing today, and the risks associated are many. If we don’t manage to reduce greenhouse gas emission quickly, the consequences can be severe. The risks related to climate ... -
Analysis of Jacket type fixed platforms – Effect of various mass modelling approaches for Topsides on structural response
