Analyse og dimensjonering av Halsafjordens strekkstag understøttede hengebro utsatt for støt fra store skip
Holm, Jørgen Thode Gryteland (Master thesis, 2016)I 2014 la Stortinget frem ambisjonen om å bygge broer for å erstatte fergesambandene på alle fjordkrysningene langs E-39 mellom Kristiansand og Trondheim. Flere av fjordene er så dype og brede at det ikke er gjennomførbart ... -
Analysis and Design of Ship Collision Barriers on a Submerged Floating Tunnel subjected to Large Ship Collisions
Rødland, Sindre (Master thesis, 2017)In this thesis, the global response of a floating bridge, with a submerged floating tunnel at the midspan, is studied when subjected to high energy ship impacts. The bridge is a concept pro- posed for use when crossing ... -
Analysis Methods for Mooring Systems with focus on Viscous Drift Force Modelling
Uddin, Mohammad Irfan (Master thesis, 2015)For analyzing mooring systems, like other structural response analysis, simulation in both Frequency domain and Time domain has been carried out. Frequency domain approach uses load spectrum and transfer function to ... -
Analysis of Innovative Mooring Systems for Floating Semi-Submersible Offshore Wind Turbines
Danielsen, Oda Emilie Nilseng (Master thesis, 2017)This thesis considers the possibilities of cost reduction of the mooring system for a floating semi-submersible wind turbine by inclusion of fibre rope instead of, or together with, chain mooring lines. Polyester fibre ... -
Analysis of Ocean Farming's Steel Cage Concept in Very Exposed Waters
Hanevik, Nikolai (Master thesis, 2017)The behaviour of the offshore fish farm concept developed by Ocean Farming, a subsidiary of the salmon company SalMar ASA, has been investigated for very exposed waters. A finite element model created by Bore and Fossan ... -
Analysis of Ocean Farming's Steel Cage Concept Subjected to Environmental Loads
Eide, Arne Jakob (Master thesis, 2017)For marine structures with significant dynamics, the extreme responses are determined by time domain analyses of extreme sea states. These are based on the short-term extreme sea state selected from environmental contour ... -
Analysis of the Parametric Instability of the STC Combined Wind and Wave Energy Concept
Appiah, Sevyllen Kistnen (Master thesis, 2017)The purpose of this study is to numerically predict such unstable motions for regular and irregular wave conditions and to compare the results with the experimental observations. First, a literature study on Mathieu ... -
Analysis of Transportation and Installation of a Component of an Artificial Sea Bed
Kjelsaas, Camilla (Master thesis, 2016)The purpose of this Master's Thesis was to study the transportation and installation of a bundle component to be used in an Artificial Seabed. The bundle, which is composed of three pipes and close to 4 km in length, is ... -
Application of Data Driven control in Dynamic Positioning
Onstein, Tord Fjordheim (Master thesis, 2017)This master thesis examines the motivation of studying adaptive control, presents the framework of Unfalsified Adaptive Control (UAC) and its theoretical background. Detailed explanation is given for key features that make ... -
Assessment and Numerical Simulation of Subsea Equipment Installation in Deep Water using a Fiber Rope Deployment System
Refsnes, Emil Sund (Master thesis, 2017)The past decade has shown a fast growing subsea production market tending to complete factories on the seabed involving even more complicated infrastructure, increasing size and weight of components to be installed. Deep ... -
Assessment of Marine Riser Joints During Offshore Drilling Operation
Bay, Martine Gripp (Master thesis, 2016)Riser technology is pushed to its limits as the demand for deeper drilling operations increases. There exist no standards for the mechanical assessment of marine riser joints today, however new standards are under development ... -
An Assessment of the Current Schedule Risk Analysis Practice at Aker Solutions AS
Shetelig, Marte (Master thesis, 2016)In today s oil and gas market contractors are experiencing increased scrutiny from clients to deliver according to success criteria such as cost, time and quality. A study made by EY (2014) revealed that 64% out of 365 ... -
Assessment of wave power for sea states at different sites
Lothe, Marie (Master thesis, 2018)The aim of this thesis is to investigate available and captured wave power at five different locations on the Norwegian continental shelf; Haltenbanken, North Sea Center, Ekofisk, Utsira and Tromsøflaket. A literature ... -
