Calculation of wave forces due to extreme events in the coastal region using REEF3D - Beregning av bølgebelastninger fra ekstrem vær i kyst områder med REEF3D
(Master thesis, 2018)The objective of this study is to validate that the Computational Fluid Dynamics (CFD) model REEF3D can capture the singularities of the structure-wave interaction in coastal regions. The two tasks established to achieve ... -
Fatigue Assessment of Offshore Wind Turbine Support Structures with the Frequency Domain Method
(Master thesis, 2015)Offshore wind energy has shown great potential and can be a great contributor when it comes to solving some of the climate challenges that the world faces today. However, both design and operational cost has been a limiting ... -
Finite Element Simulations of Unconsolidated Keel Actions from First-Year Ice Ridges. - A Comparison of a Numerical Model and Analytical Equations from ISO 19906:2010
(Master thesis, 2015)The thesis aimed for an assessment of the current standard for determination of the keel rubble actions from a first-year ice ridge. ISO 19906:2010 (2010) gives regulations for determination of these loads, based on the ... -
Numerical Modelling of Arctic Coastal Hydrodynamics and Sediment Transport
(Master thesis, 2016)Coastal areas are experiencing an increase in human population and activities, both in temperate and in Arctic areas. This change in the coastal areas requires that the areas are safe and reliable in order to not put human ... -
Sensitivities in fatigue analysis of offshore wind turbine support structures
(Master thesis, 2016)A fatigue analysis gives an answer to the question of whether a structure will resist fatigue throughout its lifetime or not. The hot spot stress approach is one of the methods used to find the solution, by looking at ... -
Simulation of floating bodies in waves using REEF3D
(Master thesis, 2017)The aim of this thesis is the validation of the 6 degrees of freedom (DOF) algorithm implemented in REEF3D for floating bodies. The 6DOF of a free-floating structure are three displacements in each axis and three rotations ... -
The Compliant Tower Concept for Offshore Wind Turbines
(Master thesis, 2018)Offshore wind turbines are getting larger and the water depths where they are located are getting deeper as well. This causes problems of eigen frequencies for rigid structures where a jacket structure could be too expensive ... -
Vortex Induced Vibrations of Slender Catenary Structures
(Master thesis, 2015)A wide range of offshore science and engineering applications utilize slender catenary-shaped structural elements in their design. These applications include moorings and steel catenary riser designs. The susceptibility ...
