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 Influence of Adjustments in Cyclist Arm Position on Aerodynamic Drag Using Computational Fluid Dynamics
(Peer reviewed; Journal article, 2020-06)In professional cycling, even small adjustments in position could mean that valuable seconds are gained over the course of a time-trial race. This study investigates the influence of arm position on the aerodynamic drag ... -
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 mechanical properties of false banana/glass fiber reinforced hybrid composite materials
(Peer reviewed; Journal article, 2020)The objective of the work presented in this article is to investigate the mechanical properties of false banana/glass fiber reinforced hybrid composite materials at different fiber volume fractions and orientation of hybrid ... -
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 Rotor Efficiency with Varying Rotor Pitch Angle for a Coaxial Drone
(Peer reviewed; Journal article, 2022-04)Coaxial rotor systems are appealing for multirotor drones, as they increase thrust without increasing the vehicle’s footprint. However, the thrust of a coaxial rotor system is reduced compared to having the rotors in line. ... -
