(PhD thesis UiS;256, Doctoral thesis, 2015-06-11)Any organization whose business model is based on production relies, and is dependent, on providers of raw material which it transforms into products. Customers’ demand for products, and thus the producing firm’s demand ... -
Analysis and Modelling of the Bjørnafjorden Floating Bridge subjected to Earthquake and Tsunami loads
(Master thesis, 2022)The ferry free E39 project includes the crossing of several demanding straits at the Norwegian west coast. Among them is the 5km wide and 600m deep Bjørnafjord located south of Bergen. To construct a floating bridge over ... -
Analysis and Optimization of rigid pipeline with inline structures
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013-06-17)Advanced modern technologies and growing demand for oil and gas has led to the discovery and development of smaller and remote fields that were once considered uneconomical. They are made economically more viable by employing ... -
Analysis and the possibility of application of the technologies of capture and storage of carbon dioxide used in Norway for Russian offshore
(Masteroppgave/UIS-TN-IKM/2017;, Master thesis, 2017-06-15)Global climate change is long-term risk related to the accumulation of carbon dioxide (CO2) and other greenhouse gases in the atmosphere. Development and use of capture and storage technology in the underground formations ... -
Analysis for model verification of Torque, Drag and Hydraulic Modules in Oliasoft Welldesign Software
(Master thesis, 2022)Drilling through the subsurface is a complicated process that frequently results in technical challenges. Understanding and anticipating drilling problems, as well as their causes and planning remedies, are essential for ... -
Analysis of 3D post-stack data from offshore east Scotland
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012-06-29)This study concentrates on reprocessing a cube of post-stack 3D seismic data from offshore East Scotland to improve resolution of the data. The main application of the reprocessing is to allow for a better interpretation ... -
Analysis of a semi-submersible floating offshore wind turbine subjected to ship collisions
(Master thesis, 2021)Wind energy has enormous potential in reducing greenhouse emissions and curbing global warming. The number of installed offshore wind turbines has been continuously growing worldwide in recent years. Since offshore farms ... -

Analysis of a ship-bridge collision at Nordhordland Bridge
(Master thesis, 2023)The Nordhordland Bridge, a floating bridge located in Norway, spans a length of 1246 meters and was completed in 1994. Over the years, the bridge has experienced two instances of ship collisions so far, resulting in minor ... -
Analysis of an offshore lifting operation according to DNV - How to find the characteristic load by repeated dynamic simulations in the time domain
(Masteroppgave/UIS-TN-IKM/2016;, Master thesis, 2016-06-08)In order to analyze a lift offshore performed from a vessel, focus is often put on preparing a good model of the main lifted object, the vessel motions (RAOs), the crane characteristics plus the sea state characteristics. ... -
Analysis of borehole failure related to bedding plane
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Borehole instabilities during drilling are more common in shale formations than in most other rock formations. Shale make up more than 80% of sediments and rocks in siliciclastic environments and about three quarters of ... -
Analysis of by-products from XLPE Production for cable insulation
(Masteroppgave/UIS-TN-IMN/2009;, Master thesis, 2009)Polyethylene is used in the manufacturing of cables. Because of the amount of high voltages which is transmitted through the cables at elevated temperatures, crosslinking of PE is necessary for stabilizing the insulation. ... -
