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 ... -
Analysis of new titanium modular stress joint (MSJ) for subsea completion and workover operations
(Masteroppgave/UIS-TN-IKM/2011;, Master thesis, 2012-06)A stress joint is a transitional joint that when used can be located both at the top and bottom of an offshore riser string. The main idea of the stress joint is to have a tapered section between the movement in the riser ... -
Analysis of operability in installing heavy subsea modules
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-09)Today (2015) subsea technology is a big part of the oil and gas industry. New subsea solutions are developed rapidly and large components that previously were placed on a platform are now being moved subsea towards the ... -
Analysis of post-tensioned concrete bridge constructed using incremental launching method
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06)The aim of this thesis is to gain a broader understanding of bridge construction methods and to analyse a bridge constructed in stages. To do so, a model is created for analyses in the frame software NovaFrame. The ... -
Analysis of predicting terminal velocities and impact energies of dropped objects falling through sea column
(Master thesis, 2023)Many offshore operations include risks that might lead to catastrophic consequences. One of the most common offshore risks is the unintentional drop of objects during various marine operations. This work is divided into ... -
Analysis of ROV thrusters and small marine propellers at specific rotational speeds
(Masteroppgave/UIS-TN-IMBM/2018;, Master thesis, 2018)Thrusters are vital for the functionalities of remotely operated vehicles (ROVs). The development of thruster design is a trade-off between cost, thrust force, physical weight and size. Furthermore, it is known that problems ... -
Analysis of the applicability of LNG production as exemplified by the Shtokman gas condensate field
(Master thesis, 2021)In the modern world, liquefied natural gas plays an increasing role; its consumption grows from year to year. Liquefied natural gas is relevant since liquid form gas occupies 600 times less volume, is environmentally ... -
Analysis of the Life of Field concept and its fitness to the future subsea asset maintenance on Norwegian Continental Shelf
(Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2014-06-15)The main scope of this master thesis is to analyse subsea asset maintenance on Norwegian Continental Shelf (NCS) and to evaluate the fitness of the Life of Field (LoF) concept to the future subsea asset maintenance on NCS. ... -
ANALYSIS OF THE METHOD OF UTILIZATION OF ASSOCIATED OF ASSOCIATED PETROLEUM GAS ON OFFSHORE PLATFORMS BY MEANS OF WATER-GAS EJECTION
(Master thesis, 2023)This master's thesis is devoted to the analysis of the efficiency of utilization of associated petroleum gas by means of water-gas ejection. Associated petroleum gas is a significant source of greenhouse gas emissions into ... -
Analytic Hierarchy Process Based Prioritization of Bending vs. Welding of piping Bends: a Technical and Economically Comparison of the Methods
