Torque and drag analyses of North Sea wells using new 3D model
(Masteroppgave/UIS-TN-IPT/2011;, Master thesis, 2011)Deviated oil and gas wellbore sections keep getting longer. This is due to the fact that more fields are reaching their mature phase and due to the fact that the technical development allows us to. The number of platforms ... -
Torque and Drag Friction Model: Implemented Friction Factor Dependency of Temperature
(Masteroppgave/UIS-TN-IPT/2016;, Master thesis, 2016-06-15)We investigated the friction factor dependency of temperature. “Friction factor” is a parameter in the calculations of torque and drag. Increased well reach is dependent on accurate torque and drag modeling. We proposed ... -
Torque Transfer System for offshore Turret Production System
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2020-06)Turret production systems allow Floating Production Storage and Offloading (FPSO) units to weathervane and thus significantly reduce environmental loads on the mooring system. There are several different variants of such ... -
Torsional loaded towhead foundation
(Master thesis, 2022)Foundations are made to withstand and transfer loads to the soil layer beneath. Soil bearing capacity is defined as the soil's ability to support all acting loads. It is preferable to have a foundation with pure vertical ... -
Total synthesis of tubastrine and 3-dehydroxy tubastrine by microwave-assisted cross-coupling reactions
(Journal article, 2015-10)The first syntheses of tubastrine and 3-dehydroxy tubastrine are described. The target compounds were prepared in four consecutive steps from commercially available starting materials. The central scaffold was formed by a ... -
Totalentrepriser og tilrettelegging for vinterarbeider
(Masteroppgave/UIS-TN-IØRP/2011;, Master thesis, 2011)Byggebransjen i regionen er preget av stor aktivitet, både med utbygging av boliger, industribygg, offentlige bygg og infrastruktur. De økonomiske konsekvensene som fulgte av kuldeperiodene tilsier at noe bør gjøres for ... -
Totalforsvaret - Kjennskap og vennskap
(Master thesis, 2023)Totalforsvaret i Norge er en fellesbetegnelse for den sivile beredskapen og det militære forsvaret i landet, og omfatter den gjensidige støtten og samarbeidet mellom den sivile og militære siden for å forebygge, planlegge ... -
Totalforsvaret: Et Begrenset Samvirke
(Master thesis, 2023)I nyere tid har det globale, nasjonale og regionale sikkerhetsbilde vært under konstant endring. For å håndtere stadig mer komplekse kriser har den norske stat videreutviklet Totalforsvarskonseptet med et bevisst fokus på ... -
Toward Separation and Characterization of Asphaltene Acid and Base Fractions
(Peer reviewed; Journal article, 2021-08)Chemical inhibition of asphaltene deposition is considered a cost-effective way to prevent the harsh consequences of asphaltene instability in the produced crude. Thus, a careful screening of asphaltene inhibitors is crucial ... -
Towards a framework for environmental risk assessment of CCS: subsea engineering systems
(Master thesis, 2022)Nowadays, we are observing a continuous rise in trends of greenhouse gasses’ concentration in the atmosphere, especially of carbon dioxide, and this is, in great part, attributable to human activities. The first detrimental ... -
Towards a Low-Carbon Future for Offshore Oil and Gas Industry A Smart Integrated Energy Management System with Floating Wind Turbines and Gas Turbines
(Peer reviewed; Journal article, 2023)Decarbonizing offshore oil and gas fields is crucial in the global fight against climate change. To achieve this objective, the offshore oil and gas industry has embraced innovative energy systems, including microgrids ... -
Towards a risk-based decision support, parameterization of hindcast data to an offshore installation duration in offshore wind farm planning phase
(Masteroppgave/UIS-TN-IMBM/2020;, Master thesis, 2021-01)For the planning stage in any wind farm development, there are many concepts and locations to be analyzed at the point of cost, schedule, and project shareholders. Especially, the marine operation requires careful planning ... -
Towards a Taylor-Carleman bilinearization approach for the design of nonlinear state-feedback controllers
(Peer reviewed; Journal article, 2022)The Carleman bilinearization is an approach that performs an exact conversion of a finite-dimensional nonlinear system into an infinite-dimensional bilinear system. A finite-dimensional system is later obtained through a ... -
Towards an understanding of learning within the Norwegian fire and rescue services – focusing on tunnel fire safety
(Peer reviewed; Journal article, 2022)Purpose The purpose of this paper is to study how learning within the fire and rescue services may be conceptualized, with special attention paid to tunnel fire safety. Previous studies have developed a model to understand ... -
Towards Bayesian Estimation of Compartmental Models for COVID-19
