Analyses of Jacket Platforms under Ship Collisions
(Masteroppgave/UIS-TN-IMBM/2018;, Master thesis, 2018)Ship collisions with jacket platforms constitute a risk to the facility integrity, the personnel and the environment. Visiting vessels are used in the Norwegian Continental Shelf to handle different goods and materials for ... -
Analysis and Optimization of rigid pipeline with inline structures
(Masteroppgave/UIS-TN-IKM/2013;, Master thesis, 2013-06-17)Advanced modern technologies and growing demand for oil and gas has led to the discovery and development of smaller and remote fields that were once considered uneconomical. They are made economically more viable by employing ... -
Analysis and the possibility of application of the technologies of capture and storage of carbon dioxide used in Norway for Russian offshore
(Masteroppgave/UIS-TN-IKM/2017;, Master thesis, 2017-06-15)Global climate change is long-term risk related to the accumulation of carbon dioxide (CO2) and other greenhouse gases in the atmosphere. Development and use of capture and storage technology in the underground formations ... -
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 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 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 ... -
