Design of Mooring Systems for Large Floating Wind Turbines in Shallow Water
(Master thesis, 2018)Hywind Scotland is the first operational floating wind turbine park in existence. It was developed by Equinor and is located off the coast of Scotland at a water depth of approximately 105m. In this thesis, a time domain ... -
Design optimization of offshore construction vessels
(Master thesis, 2016)The topic of this thesis is optimization of ship design with regards to operational performance. 4 VARD Offshore Subsea Construction Vessels are analysed to find the optimum compromise of operability versus required power, ... -
Development of a new Navier-Stokes Solver using a Generalized HPC method for the Pressure Poisson Equation
(Master thesis, 2016)The computational cost of solving the Navier-Stokes equations numerically is too high for most full-scale applications, especially within the marine field. Many marine structures are defined as large volume structures. For ... -
Development of a Simulation Model for Propeller Performance
(Master thesis, 2015)The simulation model PropSiM for simulation of propeller performance has been developed and implemented into Simulink. The simulation model generates a time domain solution to the six degree of freedom propeller forces in ... -
Distributed propulsion for ships
(Master thesis, 2017)It is anticipated that using distributed electric propulsion (DEP) on conventional ships will increase the total propulsive efficiency. This is mainly due to two reasons; firstly, because the total propeller disk area can ... -
Dynamic Analysis of ROV Operation

(Master thesis, 2015)The possibility to use Artificial Neural Network for estimating ship resistance and propulsion coefficients are investigated. Different ANNs are tested by varying input parameters, network size and complexity and division ... -
Estimation of Extreme Response - in a Jack-up Platform by Application of Stochastic Methods
(Master thesis, 2015)Abstract This thesis investigates different stochastic methods for estimating the extreme response on a jack-up platform in the North Sea. The extreme response of jack-ups is often heavily affected by dynamics and thus ... -
Estimation of Hydrodynamic Coefficients by CFD for Application to Subsea Protection Covers
(Master thesis, 2017)The background for this thesis is the limiting weather window experienced when deploying subsea structures. By following today's industry standard the allowable sea states for which structure deployment can take place is ... -
Evaluation of Seakeeping Capabilities of a Floating Solar Plant
(Master thesis, 2018)The Norwegian company Ocean Sun has proposed a concept of a floating solar plant as an alternative to conventional land-based installations. This thesis reports the results from a model test on the suggested concept, based ... -
Experimental and Numerical Investigation of Floating Solar Islands
(Master thesis, 2017)In this master thesis, the dynamical behavior of a floating solar island in waves and current has been investigated. The solar island consists of a torus were the inner part is covered with a membrane. Underneath the ... -
Experimental and Numerical Investigations of Global Motions and Slamming Loads on an Aquaculture Feed Barge
(Master thesis, 2018)Local slamming on an aquaculture barge will occur on a deck that is located lower than the main deck. The problem is dependent on the global motions of the structure. If the structure has decks that are located at the port- ... -
