A comparison of various approaches for predicting extreme wave induced response for design of offshore structures
(Masteroppgave/UIS-TN-IKM/2014;, Master thesis, 2014-06-15)Offshore structures are exposed to environmental loads such as waves, wind, currents etc. and it is important to understand how the structures behave under different conditions. In this thesis the main focus has been on ... -
A comparison of working stress design and reliability based casing design
(Masteroppgave/UIS-TN-IEP/2019;, Master thesis, 2019-06-15)Working stress design is the most common design method used on the Norwegian continental shelf and its simplicity makes it easy to understand. However, other methods as the reliability based design gives a different view ... -
A comparison study of pressure vessel design using different standards.
(Masteroppgave/UIS-TN-IKM/2012;, Master thesis, 2012)Due to a recent pressure vessel design error (see chapter 1.2.7) the design methods used for pressure vessel design is investigated. Several codes are currently available for design and analysis of pressure vessels. Two ... -
A Comparison Study of Value at Risk and Expected Shortfall
(Master thesis, 2017-06-12)This thesis evaluates the performance of Value at Risk (VaR) and Expected Shortfall (ES) for four portfolios during different scenarios. Both historical VaR and normal VaR together with ES have been calculated for two ... -
A complete synthesis of an N-spirofused iminosugar from L-xylose; a potential cholinesterase inhibitor for treatment of Alzheimer’s disease
(Bachelor thesis, 2022)In this bachelor’s project we present a complete synthesis of an N-spirofused iminosugar II with a stable positive charge on the spirocyclic nitrogen atom that together with the hydroxyl groups are expected to establish ... -

A comprehensive drilling unit tender evaluation model based on value drivers for a mature project
(Master thesis, 2023)The selection of a drilling unit in a tender process has a significant impact on the total costs for a field development project. This impact affects both commercial, technical and non-technical aspects that goes beyond ... -
A comprehensive experimental investigation of MWCNTs in oil-well cementing and the development of a new empirical model for UCS estimation
(Masteroppgave/UIS-TN-IEP/2018;, Master thesis, 2018-06-15)Cement is the primary barrier in oil and gas wells and the NORSOK D-010 Standard have very specific requirements for said cement. Amongst others, it states that cement should be impermeable, ductile, strong and resistant ... -
A compressible two-phase model with pressure-dependent well-reservoir interaction
(Journal article; Peer reviewed, 2013)This paper deals with a two-phase compressible gas-liquid model relevant for modeling of gas-kick flow scenarios in oil wells. To make the model more realistic we include a natural pressure-dependent well-formation ... -
A computational model of DOPA regulation, dopamine synthesis in the presynaptic neuron, and release into the synaptic cleft
(Master thesis, 2022)Background: Neurotransmitters and the way neurons communicate with each other have received a lot of attention in recent decades. Dopamine is one of the most important neurotransmitters. Unbalanced levels of dopamine can ... -
A conversational framework for mulitple modalities
(Bachelor thesis, 2022)This paper is concerned with creating conversations around the ECIR conference with multiple modalities. We use a Furhat robot from Furhat robotics to have a physical presence and handle voice. Rasa addresses the AI component ... -

A Cost-Efficient Approach to Rigless P&A of Platform Wells
(Master thesis, 2021)The number of wells to be abandoned on the Norwegian Continental Shelf will increase in the forthcoming years. As a consequence, significant expenditures will be required paid by the individual companies, the state and the ... -
A Decision Analysis Framework for Offshore Green Ammonia Project Investments
(Master thesis, 2021)Ammonia has great importance to our daily lives – it is used in household cleaning products and to make agricultural fertilizers. Recently it has attracted attention from the energy sector, since it can be used as a ... -
A Decision Analysis Framework for Optimizing Electrification of Offshore Hydrocarbon Production Facilities for CO2 Emission Reduction
(Master thesis, 2021)The oil and gas industry has been increasingly focusing on sustainability and emissions in their offshore production facilities, where 80% of emissions come from the generation of electricity for powering their platforms ... -
A Decision Model for Executing Plant Strategy: Maintaining the Technical Integrity of Petroleum Flowlines
(Journal article; Peer reviewed, 2012-05)The ‘strategic’ management of technical integrity has become a high profile subject matter over recent years within inspection and maintenance of assets in the process industry. The assets such as production and ... -
A decision support system for multi-target geosteering
(Journal article; Peer reviewed, 2019-12)Geosteering is a sequential decision process under uncertainty. The goal of geosteering is to maximize the expected value of the well, which should be defined by an objective value-function for each operation. In this paper ...
