Analysis of an offshore lifting operation according to DNV - How to find the characteristic load by repeated dynamic simulations in the time domain
(Masteroppgave/UIS-TN-IKM/2016;, Master thesis, 2016-06-08)In order to analyze a lift offshore performed from a vessel, focus is often put on preparing a good model of the main lifted object, the vessel motions (RAOs), the crane characteristics plus the sea state characteristics. ... -
Analysis of cable vibrations at Stavanger City bridge
(Masteroppgave/UIS-TN-IMBM/2019;, Master thesis, 2019-06-14)After the opening of the cable-stayed bridge Stavanger City Bridge in 1978 there have been reports of vibrations of the stay cables. The bridge is 1066,6 m long, and has a main span of 185 m. The main span is supported by ... -
Analysis of drilling wastes disposal methods effectiveness in Russian arctic offshore fields
(Masteroppgave/UIS-TN-IKM/2017;, Master thesis, 2017-06)Oil and gas wells have been drilled for over a century. In the early years of the industry, little attention was usually given to suitable management of drilling wastes. In accordance with the legislation of the Russian ... -
Analysis of field measurement data from the Lysefjord bridge in relation to main cables wire fracture
(Master thesis, 2022)A 637-meter suspension bridge located in Rogaland county, Norway, which connects the two municipalities of Strand and Sandnes, is known as the Lysefjord Bridge. The bridge is located in Rogaland county, and the bridge ... -
Analysis of forces in a subsea wellhead system supported by NeoDrill conductor anchor node
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-15)During drilling operations the marine drilling riser is exposed to environmental loads like waves and currents, as well as loads from the rig. These environmental loads are transferred from the riser to the wellhead system. ... -
Analysis of global forces in the wellhead/wellhead connector as a function of wellhead lateral support and stiffness
(Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2014-06-16)During the life of a well (typically 20 years), a number of operations need to be performed that requires the wellhead/wellhead connector to connect directly to a rig through a riser system. While connected to the vessel ... -
Analysis of Greenhouse Gas Emissions from Offshore Wind Turbines
(Master thesis, 2022)Renewable energy resources such as offshore wind turbines are considered as if they do not emit greenhouse gas emissions, as greenhouse gases are not emitted from these resources during electricity generation. However, ... -
Analysis of Jacket type fixed platforms – Effect of various mass modelling approaches for Topsides on structural response
(Masteroppgave/UIS-TN-IKM/2016;, Master thesis, 2016-06-15)A fixed platform in shallow waters is supported on a Jacket structure with a heavy Topside over it. The Jacket design is designed for various limit states including the ultimate limit state (ULS), serviceability limit ... -
Analysis of mooring systems for offshore vessels in deep waters
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012-06)This thesis is centered on the study and comparison of different mooring/anchoring systems for offshore vessels in deep waters. FPSO’s (Floating, Production, Storage and Offloading platforms), Light Weight Intervention ... -
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 ... -
