Analysis of mooring wire rope termination with respect to bending fatigue
(Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2014-06-16)Mooring lines that are used on floating offshore units are subjected to bending at the end termination. Over-bending in some cases may cause the mooring line to suffer damage from fatigue. A countermeasure for this ... -
Controlled lateral buckling design of pipelines
(Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2014-06-16)Constrained high temperature and pressure pipelines (HPHT) are subjected to global buckling due to plane strain condition developed by virtual anchorage of soil friction resistance and subsea facilities. Any uncontrolled ... -
Design of subsea spools: Investigating the effect of spool size
(Masteroppgave/UIS-TN-IKM/2015;;, Master thesis, 2015-06-15)Rigid horizontal spools provide the connection between flowlines and subsea structures. A typical subsea development may consist of a number of wells and subsea structures, which each need to be tie-in with the help of ... -
Development concepts for the northern Caspian sea
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)Today the Northern Caspian Sea is considered to be a very perspective region for oil and gas growth. However, the challenges encountered in the Northern Caspian Sea are not usually met in such combination in another regions, ... -
Feasibility study of the Ayashkinskoye license block (Sakhalin offshore) development
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06)Despite several successful existing offshore Russian projects such as Prirazlomnoye, Arkutun-Dagi, Piltun-Astokhskoye, Chayvo and Kirinskoye, Russian continental shelf remains to be a unique perspective for future exploration ... -
Lateral-Torsional Buckling of Steel I-Beams - An Analytical, Experimental and Numerical Study
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06)This thesis compares results from experimental and numerical analyses of structural steel I-beams subjected to lateral-torsional buckling due to a vertical point load located at the mid-span. The aim is to find a suitable ... -
Modellering og Elementanalyse av Sandwichkomposittmaterialer for utriggere
(Masteroppgave/UIS-TN-IKM/2011;, Master thesis, 2011)Hovedformålet med oppgaven er å finne en metode for beregning av sandwichkompositter. Metoden som er utarbeidet skal brukes til å analysere en utrigger laget av Green Bay Systems. I tillegg skal enkelte stålkomponenter på ... -
Optimization of wiresheave
(Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2014-06-06)The objective of this thesis is to optimize a 72” (1828,8 mm) wire sheave with respect to weight and rotational inertia. The sheaves are used as pulleys on derrick structures. Seven different design concepts were designed ... -
Phenomenon of pipeline walking in high temperature pipeline
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013)The thesis describes the phenomenon of pipeline walking by specifically focusing on a short and high temperature pipeline and identifies key parameters of it in terms of the pipeline design. Moreover, a literature study ... -
Prediction of response and damaged length of a subsea pipeline after a full bore rupture
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)The combination of oil and gas reservoirs in sea areas with high shipping traffic brings some challenges for engineers. One of these challenges is related to subsea pipeline systems specially where water depth is classified ... -
Protection of subsea pipelines against ice ridge gouging in conditions of substantial surface ice
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)The development of Arctic offshore hydrocarbon fields involves transportation systems for oil and gas, which are represented either by tankers shipping or by pipeline systems. The later have sustained behavior with respect ... -
Vortex induced vibration (VIV) analysis of subsea jumper spools
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)Subsea rigid jumpers are usually rigid steel pipe sections that provide the interface between subsea structures, such as pipelines to manifolds, trees to flowlines and pipelines to risers. Each jumper shall be designed ...
