(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-06-29)In this thesis, numerical simulation of ultrasonic testing is developed by modeling three different materials including Perspex, water, and steel in each model. Procedures of calibration of An angle probe including timebase ... -
Numerical Simulation of VIV of Risers with Staggered Buoyancy Elements
(Masteroppgave/UIS-TN-IKM/2016;, Master thesis, 2016-06-15)Steel Lazy Wave Riser (SLWR) is an attractive deep water riser system design, which allows the platform motion to be decoupled from the touchdown point (TDP) of the riser. When subjected to external flow, both buoyancy ... -
Numerical Simulations of Flow Over Bottom-Mounted Structures at High Reynolds Number
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2019-06)A common challenge in on-bottom stability design is to select accurate hydrodynamic quantities, such as drag and lift coefficients, to compute the forces on structures subject to fluid flow. The objective of the present ... -
Numerical simulations of gas-liquid two-phase flow induced forces on 90-degere elbow structures
(Master thesis, 2023)90-degree elbow structures such as pipelines with bends and rigid jumpers, are commonly used for flow transportation in subsea systems. The produced flow from the subsea wells is normally a multiphase flow which is a mixture ... -
Numerical Simulations of Near-Wall Vortex-Induced Vibrations of two Circular Cylinders in Tandem
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-15)Free-spanning subsea pipelines may experience vortex-induced vibrations (VIV) when exposed to fluid flow. These resonant motions can cause fatigue-related problems and in some cases failure of the pipe. A common configuration ... -
