A comparison of cold strained and solution annealed bolts in super duplex stainless steel in regards to stress corrosion cracking and pitting resistance
(Masteroppgave/UIS-TN-IKM/2016;, Master thesis, 2016-06-08)Corrosion place a high cost on the society and selecting the wrong materials in certain environments may have catastrophic consequences. When selecting materials there is also the different manufacturing methods to consider ... -
Analysis of Jacket type fixed platforms – Effect of various mass modelling approaches for Topsides on structural response
(Masteroppgave/UIS-TN-IKM/2016;, Master thesis, 2016-06-15)A fixed platform in shallow waters is supported on a Jacket structure with a heavy Topside over it. The Jacket design is designed for various limit states including the ultimate limit state (ULS), serviceability limit ... -
CFD Modelling of Turbulence around Offshore Structure
(Masteroppgave/UIS-TN-IKM/2016;, Master thesis, 2016-06-15)Leakages of methane from the seabed is a common problem for oil companies, and they are held responsible for leakages surrounding the platforms at sea. These leakages has to be monitored in some way, and Stinger Technology ... -
Life extension of ship-shaped floating production units
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-06)In the last two decades, the number of floating, production, storage, and offloading units (FPSOs) deployed internationally has increased rapidly. Many of them are still young but have already started ageing. The objective ... -
Mechanical and microstructual investigation of 3D-printed Alloy 625
