Dynamic Collapse of the Hull Girder in a Container Ship in Waves
(Master thesis, 2016)The interest on the influence of dynamic effects on the hull girder loading has increased in the last years. Research shows a high influence of whipping and springing on the fatigue loading. The influence on the extreme ... -
Dynamic comparison of a railway catenary section upgrade by field measurement assessments
(Journal article; Peer reviewed, 2017)The pantograph-catenary interaction is crucial for running trains on electrical railway lines. The coupled dynamic problem of an in space stationary system, the catenary system, and a system in motion, the pantograph, is ... -
Dynamic Compensation System for Landing Objects on a Moving Ship
(Master thesis, 2016)The focus of this thesis is directed towards the difficulties that may occur during a ship-to-ship load transfer operation at sea conditions. Today few ships have the ability to exchange motion-data about the motion dynamics, ... -
Dynamic consequence analysis of marine electric power plant in dynamic positioning
(Journal article; Peer reviewed, 2016)Diesel-electric power and propulsion systems with electric thrusters are the industry standard for vessels with dynamic positioning (DP) systems. Diesel engines are paired with generators in generator sets and are used to ... -
Dynamic cruise ship contingency monitoring and risk assessment based on a fuzzy logic approach using AIS data
(Master thesis, 2020)Hensikten med denne masteroppgaven er å utvikle en modell for dynamisk beredskapsovervåkning av cruiseskip. Beredskapsovervåkning av skip forstås som en måte å observere et spesifikt skip og dens omgivelser, for å videre ... -
Dynamic domain decomposition strategy coupling lattice Boltzmann methods with Finite differences approximations of the Navier-Stokes equations to study bodies in current
(Chapter; Peer reviewed, 2015)A Domain-Decomposition (DD) strategy is proposed for problems involving regions with slow variations of the flow (A) and others where the fluid features undergo rapid changes (B), like in the case of steady current past ... -
Dynamic Efficiency Modeling of a Marine DC Hybrid Power System
(Chapter, 2021)With the share of high-power electronic converters, the emerging marine DC hybrid power systems have been increasingly attractive for ship designers because of their higher operational flexibility. The system efficiency ... -
Dynamic energy system with a local LTTG at Leangen
(Master thesis, 2020)Denne masteroppgaven er en fortsettelse av en tidligere prosjektoppgave og evaluerer bruken av spill-varmekilder for å lage varmtvann til et leilighetsområde. Hovedfokuset er på en oversvømmet fordamper og en CO2 varmepumpe ... -
Dynamic fault-detection in shipboard electric load sharing.
(Master thesis, 2013)The main contribution of this thesis is an investigation of dierent fault detection systems that canbe used for marine diesel electric power plants.The motivation of this thesis is to develop fault detection systems that ... -
Dynamic FE-Analysis of a Vibration Damping Tool

Dynamic Identification and Modelling of a Pantograph
(Master thesis, 2018)The main objective of this thesis is to measure and determine the dynamic properties of a measurement pantograph, and then create a numerical model with the same properties. The purpose of the model is to give a better ... -
Dynamic impact of heavy long vehicles with equally spaced axles on short-span highway bridges
(Journal article; Peer reviewed, 2018)Extremely large trucks with a weight exceeding the standard require a permit before they are allowed to cross the bridges of a specific route. For the purpose of safety, an escort is often ... -
Dynamic lift on an artificial static armor layer during highly unsteady open channel flow
(Journal article; Peer reviewed, 2015)The dynamic lift acting on a 100 mm × 100 mm section of a static armor layer during unsteady flow is directly measured in a series of physical experiments. The static armor layer is represented by an artificial streambed ... -
Dynamic Load Effects and Power Performance of an Integrated Wind–Wave Energy System Utilizing an Optimum Torus Wave Energy Converter
(Peer reviewed; Journal article, 2022)To increase the utilization of wave and other renewable energy resources, an integrated system consisting of an offshore wind turbine and a wave energy converter (WEC) could be used to harvest the potential energy. In this ... -
Dynamic Load Effects on a Submerged Floating Tube Bridge with emphasis on Vortex-induced Vibrations
(Master thesis, 2017)A ferry-free highway is under planning of the Norwegian Public Roads Administration on the south-west coast of Norway. Many of the fjords are characterized as very deep and wide, resulting in a need for innovative, new ... -
Dynamic load on a Francis turbine runner from simulations based on measurements
(Journal article; Peer reviewed, 2014)The frequency of the Nordic power grid has become more volatile during recent years. This gives rise to two effects in synchronous machines. Firstly, as grid frequency changes the rotational speed of synchronous machines ... -
Dynamic load on High Head Francis turbines during start/stop
(Master thesis, 2014)Pressure measurements were performed on the Francis runner in the Waterpower laboratory at NTNU. These measurements were divided into start and stop procedures, with the generator on or off. The suggested method that was ... -
Dynamic loads on Francis turbines
(Master thesis, 2016)New installations of unregulated power to the electrical grid have led to more fluctuations in the grid frequency. Hydropower plants with large reservoirs can provide services to balance the frequency by increasing or ... -
Dynamic Loads on Francis Turbines: An Experimental Study
(Doctoral theses at NTNU;2019:64, Doctoral thesis, 2019)There is an increasing need for stable and flexible renewable energy. This calls for better lifetime predictions for Francis runners, which in turn requires more knowledge on the dynamic loads on the runner blades. This ...
