Hydrodynamic interaction between a small autonomous ship and an ROV
(Master thesis, 2021)The fully autonomous surface ships will be a reality and the ongoing construction of ships like "MV Yara Birkeland" is promising. In this context, the ongoing research project "ROV Revolution" aims to design and develop a ... -
Hydrodynamic interaction between floating bodies
(Master thesis, 2010)This thesis is written in collaboration with WindFlip AS in order to investigate the behavior of Hywind and WindFlip after the release of Hywind from the WindFlip vessel. Potential theory has been applied, and no viscosity ... -
Hydrodynamic interaction of floating bridge pontoons and its effect on the bridge dynamic responses
(Peer reviewed; Journal article, 2022)As pontoons of floating bridges respond to the dynamic actions of the wind and wave loading, additional forces are imposed on the pontoons due to the hydrodynamic interaction of these floating bodies. The wave forces on a ... -
Hydrodynamic Investigation of Central Hauling Pools for Longline Vessels
(Master thesis, 2019)Dragerbrønnen har nå blitt en industristandard for linefartøy, men der har ikke vert mye forsking og utvikling på dragerbrønnen siden det første fartøyet ble sjøsatt i 1998. Skipsredere og designere har nå funnet rom for ... -
Hydrodynamic load modeling and analysis of a floating bridge in homogeneous wave conditions
(Journal article; Peer reviewed, 2018)The Norwegian Public Road Administration (NPRA) is currently developing the E39 ferry-free project, in which several floating bridges will be built across deep and wide fjords. In this study, we consider the floating bridge ... -
Hydrodynamic loads on an inclined monopile in the splash zone
(Master thesis, 2018)The thesis is about a relatively new installation method for monopile foundations for offshore wind turbines. For this method, the monopiles are upended from horizontal to vertical position using an upending tool and a ... -
Hydrodynamic Loads on Complex Structures in the Wave Zone
(Doctoral theses at NTNU;2020:159, Doctoral thesis, 2020)The hydrodynamic loads on simplified structures relevant for deployment of subsea modules are studied in a two-dimensional setting. Experimental investigations and numerical simulations are performed. In the experiments, ... -
Hydrodynamic Loads on Marine Propellers Subject to Ventilation and Out of Water Condition
(Doctoral theses at NTNU;2019:86, Doctoral thesis, 2019)Traditionally ships and propulsion units have been optimised for operation in calm water. Consideration of hydrodynamic loads in calm water might not be enough since the propeller always operate in heavy seas subject to ... -
Hydrodynamic Loads on Net Panels With Different Solidities
(Journal article; Peer reviewed, 2020)Drag forces on nets represent the largest contribution to hydrodynamic loads on traditional fish farms, and will have a large impact on total loads on new designs utilizing netting as containment method. Precise methods ... -
Hydrodynamic Modeling of Tension Leg Platform Wind Turbines
(Chapter, 2013)In order to compute the system response of tension leg platform wind turbines (TLPWTs), it is important to accurately capture the hydrodynamic loading not only at the wave frequency, but also in the low (difference) and ... -
Hydrodynamic modelling and estimating response of a glacial ice near a drilling rig
(Chapter, 2019)Impact scenarios involving a typical drilling rig and glacial ice are studied. The goal is to better identify the important physical effects in modelling the dynamics of glacial ice in presence of waves and a floating ... -
Hydrodynamic Modelling Effects on Fatigue Calculations for Monopile Offshore Wind Turbines
(Master thesis, 2016)For shallow and intermediate water depths, monopile foundations are the most commonly used concept, and is considered the most promising with respect to the cost of energy. The typical highest structural eigenperiods of ... -
Hydrodynamic modelling of physical habitat conditions for fish in the Ekso river near Flatekval
(Master thesis, 2018)In this study, a 2D hydrodynamic model HEC-RAS is used to simulate the flood inundation, water depths and flow velocities of the river reach in the Eksingedal watercourse near Flatekval in western Norway. The objectives ... -
Hydrodynamic optimization of bulk and tank ship hulls
(Master thesis, 2016)International shipping transports more than 80 percent of global trade. Traditionally bulk carriers have been built to minimize construction cost and maximize cargo-carrying capacity, neglecting hydrodynamic characteristics. ... -
Hydrodynamic Optimization of Trimaran Workboat Hulls
(Master thesis, 2017)The object of this master thesis was to perform an initial design optimization for a trimaran concept, with the goal of minimizing the hydrodynamic resistance for a speed of 30 knots. The thesis is written in cooperation ... -
Hydrodynamic optimization of wetland restoration measures at the Storelva river floodplain with its meanders and oxbow lakes in Southern Norway
(Master thesis, 2019)The “Fellesprosjektet Ringeriksbanen og E16” is an infrastructure project in the south of Norway connecting Oslo and shortening the travel time with the new housing and develop-ment area of Ringerike. For the connection ... -
Hydrodynamic performance of sail-assisted merchant vessels
(Master thesis, 2014)The main goal of this project was to explore the different physical effects that are involved when a ship is using the technology of wing sails as propulsion. The wing sails can provide a lot of thrust, but they also create ... -
Hydrodynamic rainfall-runoff modelling for flash floods in small and steep catchments
(Doctoral theses at NTNU;2024:261, Doctoral thesis, 2024)Global warming and climate change lead to more frequent and extreme weather events. These include sudden and intense rainfall and rising temperatures which cause flash floods. In steep terrains, flash floods with high-flow ... -
