Drill string oscillations during connections when drilling from a semi-submersible platform
(Masteroppgave/UIS-TN-IPT/2012;, Master thesis, 2012)As the operational window is getting narrower, pressure control is becoming more important. Drilling from a semi-submersible platform can in this context offer new challenges as the top of the drill string will follow the ... -
Dynamic analysis of gravity based fish cage
(Masteroppgave/UIS-TN-IKM/2017;, Master thesis, 2017-07-06)With the development of economy and growth of population, we are constantly facing the challenge of decreasing fish population and increasing needs in the fish market. Aquaculture is a practical way to fulfill this demand. ... -
Estimation of slamming coefficients on local members of offshore wind turbine foundation (jacket type) under plunging breaker
(Journal article; Peer reviewed, 2017-11)In this paper, the slamming coefficients on local members of a jacket structure under plunging breaker are studied based on numerical simulations. A 3D numerical model is used to investigate breaking wave forces on the ... -
Models for water flooding, imbibition and coupled fracture-matrix flow in a fractured reservoir
(Masteroppgave/UIS-TN-IPT/2013;, Master thesis, 2013-06-17)The study of reservoir performance during waterflooding is important to reservoir engineers. Numerous analytical, semi-analytical and numerical flow models with different assumptions have been submitted over the years, ... -
Numerical Simulation and Experimental Study of Reelwell’s Heavy over Light Solution in Vertical Well Sections
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06)Reelwell has developed the Reelwell Drilling Method (RDM), including the Heavy Over Light (HOL) solution. The HOL solution allows drilling with simultaneously use of two different drilling fluids, i.e. a near static ... -
Numerical Simulation of Industrial Ultrasonic Testing of Material
(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 temperature-dependent flow dynamics in drilling operations
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-15)This thesis is a description of the research and improvements on solving hyperbolic conservation laws by defining a hybrid explicit/implicit numerical scheme. Former researches have been done by (Evje and Flåtten 2005) on ... -
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 ... -
Optimization of jars
(Masteroppgave/UIS-TN-IPT/2014;, Master thesis, 2014-07-01)Stuck pipe is a major problem for the oil industry, and getting bigger as more complex horizontal and deviated wells are drilled. What causes this problem and the ways to avoid it are presented. The main tool to unstuck ...
