Parametric Resonance of a Fishing Vessel With and Without Anti-Roll Tank: An Experimental and Numerical Study
(Chapter; Peer reviewed, 2017)Parametric resonance (PR) in roll is of concern for fishing vessels, especially in head-sea waves. Here the effect of passive anti-roll free-surface tank is investigated experimentally and numerically on realistic ... -
Parametric Roll Resonance of a Fishing Vessel as function of Forward Speed and Sea State
(Master thesis, 2011)The subject of this thesis is sea keeping and stability of a fishing vessel in regular waves, with focus on parametric roll resonance. Parametric roll resonance is resonance in roll due to time variation of a parameter, ... -
Parametric Studies of Dynamic Response for a Workover Riser
(Master thesis, 2014)A workover riser is a top tensioned riser, in essence similar to a marine riser. Workover risers differ from marine risers mainly by smaller dimensions, as well as simpler solutions at the riser ends. For instance, the ... -
Parametrisation of aquatic vegetation in hydraulic and coastal research: The importance of plant biomechanics in the hydrodynamics of vegetated flows
(Doctoral thesis at NTNU;2016:138, Doctoral thesis, 2016)Understanding the complexity of the interactions between aquatic biological systems and their physical environment is a critical condition for the sustainable management of aquatic environments. In such ecosystems, aquatic ... -
