Hydrodynamic design of high pull ROV
(Master thesis, 2010)This paper is a study of the design of a ROV with high pull force. The focus is the hydrodynamic design, but several other aspects had to be included to set feasible boundaries for the hydrodynamic design. The work is ... -
Hydrodynamic Design Principles and Structural Verification of a Hydrofoil Concept for Kiteboarding
(Master thesis, 2022)Bruken av hydrofoiler i kiteboarding har de siste ˚arene blitt stadig mer populært og vil for første gang bli inkludert i de olympiske leker i 2024. Siden oppstarten har den primære utviklingsinnsatsen vært˚a optimalisere ... -
Hydrodynamic development of a bionic pectoral fin for undersea monitoring platform
(Journal article; Peer reviewed, 2018)Bionic pectoral fins play an essential role in achieving the superior swimming ability of the bio-inspired undersea monitoring platform by producing desired movements and propulsion forces. This paper discusses the ... -
Hydrodynamic effects regarding free-fall lifeboat for compressible air in CFD simulations
(Master thesis, 2017)Free falling lifeboats are often used as a last resort evacuation system for fixed or floating offshore installations. Lifeboats are normally resting at a skid which is mounted at the mother vessel, until the hook holding ... -
Hydrodynamic effects relevant for free-falling lifeboats in wave conditions
(Master thesis, 2017)A free- falling lifeboat is a last resort evacuation system, installed on many rigid and floating offshore structures. The diving process of a free-falling lifeboat is a complex matter, as the external forces varies through ... -
Hydrodynamic Force Identification from Stochastic Vortex Induced Vibration Experiments with Slender Beams
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:179, Doctoral thesis, 2011)As offshore industry goes to deeper waters, vortex induced vibrations (VIV) becomes an increasingly challenging factor in riser design. However, VIV is still not fully understood. This thesis studies the hydrodynamic forces ... -
Hydrodynamic Interaction Among the Pontoons of a Floating Bridge: Effect of Global Responses
(Master thesis, 2018)The National Public Road Administration has made a plan to establish a ferry-free road connection between Kristiansand and Trondheim. Bjørnafjorden is one of these fjords that have to be crossed, and several solutions are ... -
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 ... -
