Description and Structural Analysis of a Marine Bridge for the Digernessund crossing
(Master thesis, 2018)The relevance of marine bridges have increased during the past years due to the plans of renewing route E$39$. Different types of marine bridges have been described in this thesis, with focus on the concepts proposed for ... -
Development of a Frequency-domain Model for Dynamic Analysis of the Floating Wind Turbine Concept - WindFloat
(Master thesis, 2016)In this master thesis a frequency domain method for dynamic response analysis of the floating wind turbine, WindFloat, has been established. The topic of response analysis in frequency domain is important for reducing ... -
Dynamic Analysis and Verification of the Universal Buoyancy System
(Master thesis, 2014)Liquefied Natural Gas (LNG) is becoming an increasingly popular alternative to traditional marine fuels, as it is a cost-effective solution so comply with the new Emission Control Area (ECA) sulphur emission regulations ... -
Dynamic Analysis of Connected Jackets
(Master thesis, 2018)The dynamic behavior of jacket platforms connected by a bridge has been studied by time-domain simulations in USFOS, which is a nonlinear finite element program. The main motivation behind studying this, is to be able to ... -
Dynamic Analysis of Floating Dock Structures
(Master thesis, 2015)This paper concerns a dynamic analysis preformed on a floating dock structure. The structure was installed by Bi-Brygga AS and failed in 2013 during a winter storm. Bi-Brygga AS offered this structure as a case study for ... -
Dynamic Load Effects on a Submerged Floating Tube Bridge with emphasis on Vortex-induced Vibrations
(Master thesis, 2017)A ferry-free highway is under planning of the Norwegian Public Roads Administration on the south-west coast of Norway. Many of the fjords are characterized as very deep and wide, resulting in a need for innovative, new ... -
Evaluation and Design of Large Precast Concrete Panels as Modules of Tanks for Smolt Breeding
(Master thesis, 2015)With increasing permissions for onshore smolt breeding, the industry may long for solutions that are competitive and robust. A part of this demand relates to breeding tanks that should be able to handle the given quantity ... -
Evaluation of Wellhead Fatigue for Drilling Risers - A Study on the Effect of Tension
(Master thesis, 2015)In the oil and gas industry today, there is a renewed focus on structural integrity of the well- head. There exists no codes or standards on how to calculate wellhead fatigue today. However, a Joint Industry Project (JIP) ... -
Fabrication of the Hywind Substructure
(Master thesis, 2016)As the technological feasibility of the Hywind has been proven through the Hywind demo project, the way forward is to check the technological and economic feasibility of upscaling the fabrication. In the last years, several ... -
Fatigue Analysis of Column-Pontoon Connection in a Semi-submersible Floating Wind Turbine
(Master thesis, 2014)In a world with ever increasing energy demands, there is a need to find new ways to harvest renewable energy. Floating offshore wind turbines could be an important energy source in the future. To make this possible a better ... -
Fatigue Analysis of Mooring Lines on the Floating Wind Turbine Hywind Demo
(Master thesis, 2013)In the last decades the focus on developing renewable energy has increased tremendously. The main reason for this is the rapid increase of population, which requires enormous amounts of energy. Eventually we will run out ... -
Fatigue Considerations based on Measurements from an Offshore Wind Turbine
(Master thesis, 2017)This thesis analyses full scale measurements from a 5 meter diameter, monopile supported, 3.6 MW Siemens offshore wind turbine, standing at about 20 meters water depth at Sheringham Shoal offshore wind farm. Strain ... -
Fatigue loads on large diameter offshore wind monopile foundations in non-operational situations
(Master thesis, 2016)The objective of this master thesis is to perform fatigue analysis on a large diameter offshore wind turbine with monopile foundation in non-operational situations. Offshore wind turbines are fatigue dominated structures, ... -
Floating Production in general, and a Parameter Study of a Flexible Riser for the Goliat FPSO in specific
(Master thesis, 2017)A floating production system (FPS) consists of a floating structure, a mooring system, anchors and risers. Such systems enable production for larger ocean depths. Risers are vertical pipes used for transportation of ... -
Fluid Structure Interaction Analysis of Abnormal Wave Slamming Events
(Master thesis, 2018)In critical sea states, slamming wave loads may cause severe structural damage to marine structures. The slamming loads are associated with fluid-structure impacts with high pressures and short durations. The structural ... -
Frequency-domain Roll Motion Analysis of a Transportation Barge Using Stochastic Linearization of Viscous Roll Damping
(Master thesis, 2018)This thesis is proposed by DNV GL, and presents a comparative study of frequency-domain and time-domain analysis of the roll motion. The goal is to perform a roll motion analysis of a barge-cargo system considering linearized ... -
Global Analysis of a Shipping Lane for a Floating Bridge
(Master thesis, 2015)The main objective of this thesis is to conduct a global analysis of a proposed shipping lane for a floating bridge that in future will operate in Halsafjorden. The model is simplified as only the shipping lane will be ... -
Hull Monitoring and Assessment of Hatch Corners and Hatch Opening Distortion
(Master thesis, 2015)Torsion is highly important for large container carriers. In order to maximize the container capacity, a large deck area is essential, which often leads to a big bow are. To simplify loading and ooading, each cargo hold ... -
