Integrity Assessment of Mechanical Properties and Microstructure in Aging Railway Bridge in Norway
(Master thesis, 2023)There is a lack of documentation about the material in century-old railway bridges in Norway, with many of which are still in operation, approaching what is conventionally deemed as their design working life. Along with ... -
Intelligent oilfield work processes - turning data into effective decision and actions
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013)The oil and natural gas, due to its important role in the economic construction society development, are sought vigorously by the Governments and oil enterprises. However, as a fossil energy, oil and gas resources were ... -
Investigating the effect of Molybdenum on Pitting Corrosion Resistance of type AISI 316L Stainless Steel in Seawater
(Master thesis, 2021)This master thesis focuses on how long it is possible to expose AISI 316L stainless steel to seawater before pitting corrosion occurs. Exposure time is of interest because seawater ingress can cause pitting corrosion in ... -
Investigation of condition based maintenance practice within Norwegian oil and gas
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)The Oil and Gas industry’s increasing demands within risk management, cost efficiency, plant availability and the technology development have led to an increased interest for monitoring of equipment for performance and ... -
Investigation of Corrosion Resistance of Duplex, Lean Duplex and Austenitic Stainless Steels in Simulated Offshore Environment
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-14)Some duplex grades are developed to replace the 300 series of austenitic stainless steels in harsh chloride applications due to superior mechanical and corrosive properties. Since the market price for nickel and molybdenum ... -
Investigation of critical time and temperature for pitting corrosion on 316SS cladding
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-06-30)The austenitic stainless steel 316L is a very common and low carbon stainless steel grade. 316L has great corrosion characteristics under harsh conditions such as seawater, acidic medias etc. The presence of molybdenum ... -
Investigation of Material Property changes in HSLA Steel due to Weld Proximity
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-09-15)Standards and specifications apply a rule of thumb when determining the distance of two adjacent weld joints, but they rarely give any clear technical justification for the predetermined values. It is vital to understand ... -
Investigation of materials which reduce CO2 in long term.
(Bachelor thesis, 2021)About one quarter of global energy use is for production of materials. The more efficient we are in the use of these materials, the better it is for the long-term reduction of CO2 and other GHG emissions. Concrete is the ... -
Investigation of necessary subsea structure modifications prior to installation of new offloading system at Gullfaks
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)Due to the extension of the Gullfaks license, Statoil needs to perform several upgrades to systems to satisfy today’s regulations. Today`s system consist of two large single point moored offloading buoys, SPM 1 and SPM ... -
Investigation of smoothing in the actuator line model for single and multi-rotor wind turbines
(Master thesis, 2022)The state-of-the-art actuator line modeling (ALM) method has been used extensively in the past decade to perform large-eddy simulations (LES) of wind turbines as fully resolved blade simulations require complex rotating ... -
Investigation of suction anchor pullout capacity under undrained conditions
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)Floating units are dependent on reliable mooring systems to ensure safety during marine operations. Suction anchors have proved to be a technologically viable and cost-effective concept. They are capable of precision ... -
An Investigation of Sustained Casing Pressure Occurring on the NCS
(Masteroppgave/UIS-TN-IKM/2017;, Master thesis, 2017-12-15)Reports from the Gulf of Mexico (GoM) show that thousands of wells exhibit sustained casing pressure (SCP), however the extent of this phenomena and its driving factors have yet to be studied in detail on the Norwegian ... -
