Wet Gas Compressor Transient Operation
(Master thesis, 2018)Over the past years, the oil and gas industry has directed its attention towards subsea wet gas compression. Previous research has demonstrated that the operation of subsea wet gas compressors represents challenges related ... -
Wet Gas Compressor Transients
(Master thesis, 2014)This master thesis considers three subtasks related to transient operation of wet gas compressors.HYSYS Dynamics is used to establish a dynamic simulation model in the first subtask. The model is designed to predict transient ... -
Wet Gas Compressors - Stability and Range
(Doctoral thesis at NTNU;2016:230, Doctoral thesis, 2016)The oil and gas industry is a large user of turbomachinery. The demand for oil and gas is consistently growing, and changing market conditions require innovative solutions. Operation and optimization of turbomachinery ... -
Wet Torrefaction of Biomass – Production and Conversion of Hydrochar
(Doctoral thesis at NTNU;2015:20, Doctoral thesis, 2015)Biomass is a renewable and carbon neutral energy resource which has a high potential for replacing fossil fuels. However, the use of biomass for energy applications is not straightforward. It is because native solid ... -
Wettability Alteration Measurement Using Zeta Potential
(Master thesis, 2021) -
Wettability Variations within the North Sea Oil Field Frøy
(Master thesis, 2012)Wettability is one of the most important parameters governing the rate of oil recovery from a porous medium. This thesis is a study of the wettability variations within the Frøy field in the North Sea, and its effect on ... -
Wetting Properties of Springtail Cuticles: A Quantitative Analysis
(Master thesis, 2012)With the prospect of producing superhydrophobic and mechanically stable biomimetic surfaces, the water repellent properties of springtail cuticles are investigated quantitatively. The analysis is based on apparent contact ... -
Wetting State Transitions over Hierarchical Conical Microstructures
(Journal article; Peer reviewed, 2018)Advancing in a better understanding of the physics of wetting requires to be able to develop surfaces with well‐controlled roughness by controlling the microstructure morphology. In this study, patterned truncated cones ... -
What Are Demanding Operations In Subsea Work?
(Journal article; Peer reviewed, 2018)In recent years, offshore operations have changed from a focus on anchor handling and rigging to more subsea installation and IMR (inspection, maintenance, repair). Situations where large and heavy modules are placed on ... -
“What are the carrier advantages and disadvantages of IoT cargo tracking?”
(Bachelor thesis, 2020)Teknologi utvikler seg kontinuerlig og tar en større rolle i hver dagen vår. Teknologiendringene de siste årene har har vært bratt seg og forventes å fortsette. Bransjer har blitt presset mot nytenking, og skipsfartsmarkedet ... -
What Causes Schedule Overrun in Complex Engineering Projects?
(Master thesis, 2021)Denne studien er et dypdykk i estimerte arbeidstimer til komplekse ingeniørprosjekter. Gjennom eksklusiv tilgang til detaljerte økonomiske arkiver og estimater fra tidligfase, analyserer denne studien estimeringsnøyaktigheten ... -
What Have We Learned from Ivar Aasen?
(Master thesis, 2017)This master thesis addresses the topics of lessons learned, success factors, and challenges or reasons for project failure. The aim of the thesis is to contribute to the lessons learned initiative at Aker BP by assessing ... -
What is and how to develop sustainable innovation?
(Chapter, 2017)Today the terms sustainable development and sustainable innovation are often used. But what is meant by these terms, other than that they in some ways are connected to the terms ‘green’ and ‘ecological’ seen in a long-term ... -
What is going on with fatigue of additively manufactured metals?
(Journal article; Peer reviewed, 2019)This brief communication gives an overview of fatigue behaviour and assessment of additively manufactured metals. The high cycle fatigue behaviour of as‐built and post‐processed additively manufactured superalloy 718, ... -
What Is the Impact of Accidentally Transporting Terrestrial Alien Species? A New Life Cycle Impact Assessment Model
(Peer reviewed; Journal article, 2024)Alien species form one of the main threats to global biodiversity. Although Life Cycle Assessment attempts to holistically assess environmental impacts of products and services across value chains, ecological impacts of ... -
What Makes an Alliance an Alliance – Experiences from Australian Infrastructure Projects
(Journal article; Peer reviewed, 2018)This research shows that alliancing can be identified by 25 hard elements. It seems the case that no single element is unique to alliancing, but rather it is the combination of elements that really makes the alliancing ... -
What services does the agency fee in the ARA region include, and how does it compare to other European regions?
(Bachelor thesis, 2023)Denne oppgaven prøver å finne ut hvordan byråer fra et shippingknutepunkt driver sin virksomhet sammenlignet med andre fra mindre regioner, og hvilke tjenester de inkluderer i byråhonoraret. Ved å sammenligne dem med ... -
When and How Should Chloride Profiles be Calibrated for Paste Fraction?
(Peer reviewed; Journal article, 2022)Due to stochastic and systematic variations in the paste fraction, data for total chloride content are occasionally calibrated using parallelly measured calcium content as a measure of the actual paste fraction − assuming ... -
When do allocations and constructs respect material, energy, financial, and production balances in LCA and EEIO?
(Journal article; Peer reviewed, 2016)Conservation of mass and energy are essential to physical accounting, just as price and market balances are essential to economic accounting. These principles guide data collection and inventory compilation in industrial ... -
When Thermodynamic Properties of Adsorbed Films Depend on Size: Fundamental Theory and Case Study
(Peer reviewed; Journal article, 2020)Small system properties are known to depend on geometric variables in ways that are insignificant for macroscopic systems. Small system considerations are therefore usually added to the conventional description as needed. ...
