Modeling of Hybrid Marine Electric Propulsion Systems
(Master thesis, 2014)Energy storage devices integrated in diesel-electric power systems is believed to have impact also in marine applications, when it comes to emissions and fuel efficiency. For certain load conditions energy storage can act ... -
Modeling of Hydroelastic Response of Closed Flexible Fish Cages due to Sea Loads
(Master thesis, 2013)Norway is presently the worlds biggest producer of Atlantic salmon. The traditionally used open-net-structures are probably the most important reason for the Norwegian success.The very nature of aquaculture, where fish is ... -
Modeling of Seaborne Transport of Fresh Salmon - Inventory Routing with Continuous Time Formulation for a Perishable Product
(Master thesis, 2017)Norway produced 1,31 million tonnes of farmed salmon in 2015, and the production is expected to grow to 5 million tonnes in 2050. Every day, around 120 semi-trailers are on the roads, just with the mission of transporting ... -
Modeling of Technical, Human and Organizational Factors and Barriers in Marine Systems Failure Risk: Modeling of Stability Operations on a Semi-Submersible Unit with the use of Bayesian Belief Networks
(Master thesis, 2014)Offshore operations in the relatively harsh conditions on the Norwegian Continental Shelf requires a strict safety focus. In order to conduct safe operations, a range of risk analysis tools are needed to monitor the risk ... -
Modeling Operational Performance for the Global Fleet & Application of an Energy Saving Measure
(Doctoral theses at NTNU;2023:88, Doctoral thesis, 2023)In order to reduce greenhouse gas emissions (GHG) from ships at sea, various measures have been considered, such as alternative fuels with low carbon intensity, innovative ship technology, and new policies. To successfully ... -
Modeling, analysis and joystick control of the "AMV Oil Spill Fighter"
(Master thesis, 2011)The purpose of this thesis is to develop a control scheme for the Arctic Multipurpose Vessel Oil Spill Fighter vessel model using a joystick as the connection between vessel and operator. A mathematical model of the vessel ... -
Modeling, Parameter Identification and Thruster-Assisted Position Mooring of C/S Inocean Cat I Drillship
(Chapter; Peer reviewed, 2017)A thruster-assisted position mooring (TAPM) system includes different control functions for stationkeeping and motion damping for a moored offshore vessel with assist from thrusters. It consists of a conventional mooring ... -
Modeling, Simulation and Control of Hydraulic Winch System
(Master thesis, 2014)In this thesis a hydraulic low pressure winch system has been modeled using bond graph theory. The hydraulic winch system is assumed to be installed on an offshore vessel affected by environmental forces and disturbances ... -
Modelization and Analysis of Offshore Wind Support Vessels in the Scenario of the new Generation of Offshore Wind Farms
(Master thesis, 2018)The present thesis studies service operations vessels (SOV) working in operation and maintenance duties in the offshore wind industry. An analysis of the current industry situation has been carried out and then the vessel ... -

(Master thesis, 2021)Abstract will be available on 2024-11-01 -
Modelling and Analysis of a Cylindrical Flare Tower
(Master thesis, 2013)The study of a cylindrical flare tower concept proves that this novel flaretower design has great potential and could be a competetor to traditionaltruss-work flare towers. A design capable of withstanding wind and sealoads ... -
Modelling and Analysis of a Floating Bridge
(Master thesis, 2018)The Norwegian National Public Road Administration is working on a project to improve the coastal road E39, connecting the cities along the west coast of Norway. Today, this road has seven ferry crossings which are to be ... -
Modelling and Analysis of a Submerged Floating Tunnel for Crossing of the Sulafjord
(Master thesis, 2022)Fergefri E39 skal binde sammen vestkysten av Norge ved å erstatte sju ferger med bruer og tunneller. De fleste fjordkryssningene kan krysses ved bruk av kjent teknologi, men det kreves nye innovative løsninger for de ... -
Modelling and Analysis of Floating Bridge Concepts Exposed to Environmental Loads and Ship Collision
(Master thesis, 2018)The need for improving the infrastructure in Norway meets challenges when developing solutions to cross the wide and deep fjords along the coastline. The Norwegian Public Roads Administration (NPRA) is behind the ongoing ... -
Modelling and analysis of the gearbox in a floating spar-type wind turbine
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:128, Doctoral thesis, 2013)This thesis seeks to reveal and investigate important drivetrain dynamics in relation to offshore wind turbines. Emphasis is placed on drivetrains of the spar-type floating wind turbines (FWTs). FWTs are proposed to be ... -
Modelling and control of a pneumatic starting system for medium-speed gas engines
(Master thesis, 2011)This thesis investigates starting systems for marine gas engines. Large combustion engines are usually started by means of pneumatic starting arrangements. The most common ways of starting a combustion engine with compressed ... -
Modelling and Control of a Two-Body Offshore Wave Energy Converter - Evaluation of Passive Control Strategies
(Master thesis, 2015)The main motivation behind this thesis is using the renewable resource of wave energy to solve two of the most important challenges for sustainability; energy and freshwater. The DynOcean is a two-body offshore wave energy ... -
Modelling and Control of Thruster Assisted Position Mooring System for a Semi-submersible: Analysis and Model Testing
(Master thesis, 2014)For harsh weather, nonlinear effects dominate the dynamics to a larger extent than for calm weather. The low frequency dynamics of a moored vessel are excited by second order wave drift forces. To counteract the low-frequency ... -
Modelling and control of underwater inspection vehicle for aquaculture sites
(Master thesis, 2012)Underwater vehicles such as AUVs and ROVs with hovering capabilities is a promising method for inspection of net integrity in large scale, sea based, salmon farms. The location of the salmon farms cause underwater vehicles ... -
