Systematic Analysis of Experiments on Sub-Carangiform Fish Hydrodynamics
(Master thesis, 2022)Målet med denne oppgaven er å undersøke om det er en måte å systematisk samle data fra fiskesvømmeeksperimenter slik at fremtidig datautvinning for påfølgende analyse kan foregå mye raskere. Det er gjort et forarbeid for ... -
Systematic Evaluation of VIV Prediction for Riser with Partial Strake Coverage
(Master thesis, 2019)Med utgangspunkt i doktorgradsavhandlingene til Mats J. Thorsen og Jan V. Ulveseter presenterer denne oppgaven en semi-empirisk tidsplan-modell som er i stand til å predikere virvelinduserte vibrasjoner (VIV) for stigerør ... -
A systems approach to hazard identification for solar-powered and wave-propelled unmanned surface vehicle
(Peer reviewed; Journal article, 2024)Decarbonization is a trend in the maritime industry and may include the use of alternative energy sources on ships. At the same time, autonomous ships are under development. In the future, the two technologies may be ... -
A systems-theoretic approach to hazard identification of marine systems with dynamic autonomy
(Peer reviewed; Journal article, 2020)Autonomous marine systems may switch between various operational modes with different levels of autonomy (LoA), due to a rapidly changing environment and the complex nature of tasks. The dynamic autonomy brings an additional ... -
Team and Research Based Learning Methods Applied in Multidisciplinary Marine Engineering Education
(Journal article; Peer reviewed, 2019)This paper presents an integrated team-based, and research-based learning approach utilized in lecturing multidisciplinary marine engineering courses. The approach is exemplified during one month Ocean Engineering Summer ... -
Technical and Economic Feasibility Analysis of a Conceptual Subsea Freight Glider for CO2 Transportation
(Peer reviewed; Journal article, 2022)This study analyses the technical and economic aspects of a novel subsea freight glider (SFG). The SFG is an excellent replacement for tanker ships and submarine pipelines transporting liquefied CO2. The main aim of the ... -
Technical Condition Indexes and Remaining Useful Life of Aggregated Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:278, Doctoral thesis, 2008) It is a challenge to determine the remaining useful life of items having several failure modes that are dependent on age and several condition monitoring sources. Remaining useful life has always been a wanted quantity ... -
Technical condition indexes for auxiliary marine diesel engines
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:108, Doctoral thesis, 2013)Knowledge about the technical condition of a ship is an important issue. It will help in improving the planning of the maintenance actions, and giving earlier alerts to the organization if there is any development that ... -
Technical Condition Indexes for Ship Engine Auxiliary Systems
(Master thesis, 2010)The topic of my individual Master Thesis study is the expansion of the Technical Condition Index (TCI) concept, developed at the Department of Marine Technology at NTNU, as to encompass the following Ship Engine Auxiliary ... -
Technical note: Turbulence measurements from a light autonomous underwater vehicle
