Design of subsea spools: Investigating the effect of spool size
(Masteroppgave/UIS-TN-IKM/2015;;, Master thesis, 2015-06-15)Rigid horizontal spools provide the connection between flowlines and subsea structures. A typical subsea development may consist of a number of wells and subsea structures, which each need to be tie-in with the help of ... -
Design, modeling, analysis and caculation of offshore module structure
(Master thesis, 2015-06)The main object of this thesis is design, analyses and calculation of offshore module structure to ensure the required safety and the serviceability requirement against different loads and load combination (i.e dropped ... -
Dynamic analysis for the installation of offshore wind turbine foundations
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)This report looks into the possibility for using modified phased out shuttle tankers to install jacket foundations for offshore wind turbines. New massive wind mill farms are now being planned out in water depths of 40 ... -
Effect of localized corrosion on welded steel joints
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)With steel structures placed in ever increasing depths in the oil industry, inspection of the structures are increasingly more challenging. Loss of coating on a weld exposes the weld to a corrosive environment, where the ... -
Evaluation of SCFs for stiffened tubular joints
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06)In this thesis the field of stress concentration factors for use in fatigue analysis is explored. The focus is on stiffened tubular joints, which are common on offshore structures. An analysis methodology is established ... -
Forces on simplified offshore structures according to different wave models.
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)The reason for creating this thesis was because of the new and revised version of NORSOK N-003 standard. Therefore a comparison between the old and the revised version of NORSOK N-003 standard has been performed. This ... -
