Streamlined semi-automatic data processing framework for ship performance analysis
(Peer reviewed; Journal article, 2023)The hydrodynamic performance of a sea-going ship can be analyzed using data from different sources, like onboard recorded in-service data, AIS data, and noon reports. Each of these sources is known to have its inherent ... -
Pile design for X-rotor offshore wind turbine
(Peer reviewed; Journal article, 2023)For the foundations of traditional offshore structures in oil and gas industry, the dominant load is in vertical direction. For wind turbines, especially for vertical axis wind turbines, the lateral loads are increased ... -
VAWT support structure mass sensitivity due to aerodynamic load scaling
(Peer reviewed; Journal article, 2023)The X-rotor wind turbine is an X-shaped hybrid vertical axis wind turbine whose power take-off is done by horizontal axis rotors located at the tip of the lower blades. Based on an initial basic study, the present study ... -
Selective recovery of silver from copper impurities by electrodialysis: Tailoring monovalent selective cation exchange membranes by monomolecular layer deposition
(Peer reviewed; Journal article, 2023)Selective recovery of silver from secondary resources enriched with copper impurities is a well-known challenge but is urgently needed by the industry. This study addresses the challenge by developing a highly efficient ... -
Evaluating natural degassing in a river to create a baseline for comparison to technical degassing methods.
(Peer reviewed; Journal article, 2023)In Norway, a recent project used a risk matrix to identify about 200 hydropower plants ( 11 % of the total number) of being in high risk of producing air-supersaturated water. The combined installed capacity of these ... -
Challenges faced by the stakeholders during a phase transition in a collaborative delivery project
(Master thesis, 2023)Formålet med denne masteroppgaven er å undersøke utfordringene og de bakenforliggende årsakene til disse utfordringene, samt å finne mulige løsninger for å løse disse utfordringene som aktørene står overfor under en ... -
A Decentralized Droop-Based Power Management System for Ship Power Systems Using Hybrid Dynamical Systems Framework
(Chapter, 2023)In maritime transport, inspired by the automobile sector, autonomy is gaining traction in parallel with decarbonization. One of the numerous challenges in realizing fully autonomous operation in shipping is to design a ... -
Key Lesson Regarding Project Delivery Model(PDM) in Mega Suspension Bridge Projects, Case Study: PPP in 1915Çanakkale Bridge Project
(Master thesis, 2023)This master’s thesis explores the realm of mega infrastructure projects, specifically examining the 1915 Çanakkale Bridge project in Turkey as a case study. The study’s motivation arises from the Norwegian Public Road ... -
Investigating the Interaction between Degradation and Thermal Behaviour in Lithium-Ion Batteries
(Doctoral theses at NTNU;2023:446, Doctoral thesis, 2023)The overall aim of this thesis is to generate knowledge on the interplay of battery degradation and thermal behaviour. We focused on the temperature dependency of degradation on the one hand and on the effect of degradation ... -
Buckling and Post-Buckling Behaviour of Extruded Aluminium Panels Subject to the Combined Effects of Welding and Pitting Corrosion
(Chapter, 2023)The present study investigates the effects of pitting corrosion and welding, both independently and combined, on the buckling and post-buckling behaviour of extruded aluminium panels. For this purpose, a finite element ... -
Flexible operation of Francis turbines
(Doctoral theses at NTNU;2023:387, Doctoral thesis, 2023)With the planned cuts in emissions, more of the electric energy will have to come from renewable sources. Two of the largest potential sources are wind- and solar, which have the downside of also being intermittent and ... -
Deep learning-based building detection from oblique aerial images
(Master thesis, 2023)I de senere årene har fremskritt innen dyp læring og tilgjengeligheten og kvaliteten på høyoppløselige flyfoto presset grensene for hva som er mulig når det gjelder nøyaktighet og pålitelighet i automatisk bygningsdeteksjon. ... -
How Loads Interact? A Numerical Investigation of Aluminum Stiffened Panels Under Bi-Axial and Lateral Loads
(Chapter, 2023)Due to low weight, aluminum alloys are commonly used to build ferries, working boats and high-speed ships. The hull of such vessels can be designed as catamaran and trimaran for favorable hydrodynamical behavior and ... -
Biases From Spectral Leakage in Remote Sensing of Near-Surface Currents
(Journal article; Peer reviewed, 2023)Remotely measuring subsurface water currents from imagery of the wave field has become a much-used technique. We study the biases and errors in such measurements due to spectral leakage and suggest mitigating procedures. ... -
Ammonia in Dual-Fueled Internal Combustion Engines: Impact on NOx, N2O, and Soot Formation
(Peer reviewed; Journal article, 2023)The combustion of ammonia in internal combustion engines (ICE) releases nitrogen-related exhaust emissions. Numerous studies have shown that the increased formation of nitrous oxide (N2O) may offset ammonia’s carbon-free ... -
Leveraging opportunity of low carbon transition by super-emitter cities in China
(Peer reviewed; Journal article, 2023)Chinese cities are core in the national carbon mitigation and largely affect global decarbonisation initiatives, yet disparities between cities challenge country-wide progress. Low-carbon transition should preferably lead ... -
Grain refinement of Ti6Al4V by incorporating in-situ TiB nanowhiskers in laser melting deposition
(Journal article; Peer reviewed, 2023)One of the known problems in laser melting deposition (LMD) of alloys is columnar grain morphology and large grain size. Adding reinforcements is generally suggested as a viable approach to tailor the microstructure and ... -
Modular Collision Avoidance Using Predictive Safety Filters
(Chapter, 2023)The number of maritime projects is increasing yearly, including offshore applications, underwater robotics for ocean condition monitoring, and autonomous ship transport. Many of these activities are safety-critical, making ... -
