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 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 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 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 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 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. ... -
Analytical model for J-tube pull-in
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013)As long as J-tubes are installed during the platform installation, only minor thing can be changed after installation. The method implies pulling the pipeline through J-shaped tubes (J-tube). In spite of the all the ... -
Anchor damage assessment of subsea pipelines - optimization of design methodology
(Masteroppgave/UIS-TN-IKM/2015;, Master thesis, 2015-06-12)The world’s energy resources on land are getting depleted, and mush attention is given to the development of offshore fields. Over the past years, new reserves located offshore have been regularly discovered. Once the ... -
