Lifting analysis of integrated spool cover
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013)Large competition in the offshore industry requires innovative solutions to satisfy the demand. A new concept of spool installations is considered where three large spools are lifted in an integrated protection structure ... -
Lifting/Installation analysis of spool - Comparison between brace and spreader solution from a structural, operational and economical point of view
(Masteroppgave/UIS-TN-IKM/2011;, Master thesis, 2011)As large sections of production pipe are lifted and installed, forces act on the structure. If initial analyses of the structural integrity show that the pipe will fail, support elements have to be introduced. The two most ... -
Limiting operational wave criterion for spool installation lift - with emphasis on analysis and wind-wave modeling
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)Spools are rigid pipe sections which are parts of the infrastructure for transporting produced hydrocarbons and injection fluids subsea. Installing them includes a subsea lifting operation commonly carried out by use of ... -
Linear and nonlinear analyses of Røydalen bridge
(Master thesis, 2021)The aim of this thesis is to gain a broader understanding of bridge modeling and nonlinear analyses of structures. Røydalen bridge has been chosen as a case study and the modeling and analyses of the bridge has been performed ... -
Literature Review on Repair methods for Damaged Offshore Joints
(Master thesis, 2021)Offshore structures subject to severe environmental loading may exhibit fatigue damage over time. In particular, fatigue cracks are a significant concern in welded components. Previous work has been published regarding the ... -
Livssyklusanalyse av bygninger ved bruk av BIM: En case-studie
(Master thesis, 2021)A large proportion of the total emission from the building and construction industry are related to the production of building materials. In buildings with low energy needs, building materials make up a large percentage ... -
Load analysis on an offshore wind turbine structure
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)This report is written as documentation of a master thesis in the course constructions and materials at the University of Stavanger. The thesis was performed within January to June 2012 as a further research on an international ... -
Load capacity and structural response of CLT-concrete composite slabs with two different types of shear fasteners
(Master thesis, 2021)Abstract The subject of this Master thesis is to investigate the performance of the behaviour of Cross Laminated Timber-concrete composite slabs with two different types of shear fasteners by performing theoretical predictions ... -
Local joint flexibility of tubular offshore joints with eccentric brace to chord connections
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-06-30)Local joint flexibility of tubular offshore joints has been researched to be able to account for correct deflection and redistribution of member forces and moments. This has shown to improve design life prediction for ... -
Long term analyses of wave characteristics
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)The focus in this master’s thesis was to describe and compare the two long-term analysis methods: All Sea States and Peak-Over-Threshold. Both methods are equitable and commonly approved methods to estimate extreme waves. ... -
Long Term Response Analyses of a Jacket Structure with Focus on a Peak Over Threshold Approach
(Master thesis, 2022)This thesis investigates the use of long term analysis to estimate the q-probability responses of a non-linear problem. The structure subjected to the investigations is a realistic jacket found in the Norwegian Continental ... -
Loss of Integrity on Mooring Lines – Causes and Consequences
(Masteroppgave/UIS-TN-IKM/2016;, Master thesis, 2016-06-16)In the history of offshore industry, position keeping has been an essential part for allowing operations to be performed, and production to be maintained. This is often done by connecting mooring lines between the vessel ... -
Low cost deep water wells
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)A major cost-factor of drilling deep water wells today is associated with the high day rates of the larger rigs capable of drilling in such depths. Most subsea completions today are based on the 18-3/4” wellheads system. ... -
Low temperature thermomechanical treatment of corrosion resistant alloys
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013)Wear deteriorates materials and are a widespread problem in many areas of industry. To some extent, all physical materials experience wear in one form or another by moving gas, particles, fluids or a combination of these ... -
Luftinnføring i betong med Portland-flygeaske sementer – innvirkning av sementegenskaper
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2016-01-15)For å lage en frostbestandig betong tilsettes luftinnførende stoff. Dette danner et finfordelt luftporesystem som kan ta hånd om volumøkningen til vannet når det fryser. Å oppnå kravene til luftinnhold kan være krevende. ... -
