Experimental and Numerical Investigation of Residual Stress for Structural Integrity Assessment of Proximity Girth Welds
(PhD thesis UiS;, Doctoral thesis, 2023-01)Over the last decade, there has been a growing interest in the life extension of existing welded structures in offshore and renewable industry. During this phase of extension, repair of welded structures is a common practise ... -
Experimental and numerical investigation of residual stresses in proximity girth welds
(Peer reviewed; Journal article, 2023)International fabrication codes and standards provide minimum distance criteria for proximity welds, although rigorous justification is lacking. These distances are either based on practical experience or mutual agreement ... -
Experimental and numerical simulation of the recovery of oil and the effect of light oil components on CO2 flooding mechanism using sandstone reservoir.
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-29)Carbon dioxide (CO2) flooding is considered as an efficacious method of EOR. It is a complicated process as it involves phase behavior. In order to master the performance of CO2 flooding, a comprehensive investigation of ... -
Experimental and Numerical Studies of Stress Distribution in an Expanding Pin Joint System
(Peer reviewed; Journal article, 2022)Pin joints are widely used mechanisms in different industrial machineries such as aircrafts, cranes, ships, and offshore drilling equipment providing a joint with possibility of relative rotation about one single axis. The ... -
Experimental and numerical study of Bondura® 6.6 PIN joints
(Journal article; Peer reviewed, 2017)Pin joints are widely used in heavy-duty machinery such as aircrafts, cranes and offshore drilling equipment to transfer multi-dimensional shear forces. Their strength and service life depend on the clamping force in the ... -
Experimental and numerical study of the elastic SCF of tubular joints
(Peer reviewed; Journal article, 2021-07)This paper provides data on stress concentration factors (SCFs) from experimental measurements on cruciform tubular joints of a chord and brace intersection under axial loading. High-fidelity finite element models were ... -
Experimental and Numerical Study on the Slug Characteristics and Flow-Induced Vibration of a Subsea Rigid M-Shaped Jumper
(Peer reviewed; Journal article, 2023)The subsea jumper has become an essential part of subsea production systems as a gas–liquid mixing pipeline connecting the pipeline end manifold (PLEM) to the Christmas tree. During oil and gas transportation, as a common ... -
The experimental and theoretical investigation of single-crystal diamond compound refractive lenses (CRLs)
(PhD theses (TN-IMF);527, Doctoral thesis, 2020-06)In the field of X-ray optics, compound refractive lenses (usually termed CRLs) function as a focusing device for hard X-rays and they are believed to possess a lot of prominent advantages over other focusing devices, such ... -
Experimental and theoretical investigation of the mechanisms of drying during CO2 injection into saline reservoirs
(Peer reviewed; Journal article, 2023)A viable CO2 storage resource must have sufficient storage capacity, reliable containment efficiency and adequate well injectivity. Deep saline formations stand out in terms of storage capacity and containment efficiency. ... -
Experimental and Theoretical Modelling of CO2 Injectivity : Effect of Fines Migration and Salt Precipitation
(PhD thesis UiS;, Doctoral thesis, 2017-11)Adequate well injectivity is required to inject large volumes of CO2 at acceptable rates through a minimum number of wells. Mineral dissolution and salt precipitation could impair CO2 injectivity and reduce the quality and ... -
Experimental assessment of cracked tubular joints repaired with crack-deflecting holes and weld-toe grinding
(Peer reviewed; Journal article, 2023)Tubular joints in offshore structures for energy production are exposed to cyclic loading and may experience fatigue cracking. Presently, the inspection method commonly used for such structures will primarily detect whether ... -
Experimental Bench-Scale Study on Cuttings-Bed Erosion in Horizontal Wells
(Peer reviewed; Journal article, 2022)Cuttings-beds formation while drilling wellbores is a common challenge, especially for horizontal wells, as drilled particles have higher area to be deposited and form cuttings-beds, which can cause several problems such ... -
