Formation control of marine vessels
(Master thesis, 2011)As an enabling technology of coordinated multi-vessel operations, formation control has received considerable attention in recent times, with specific applications ranging from satellites in space to wheeled robots on the ... -
Installation of Offshore Wind Turbine
(Master thesis, 2011)Ingenium AS is developing a new concept for transporting and installing fixed wind turbines, mainly jacket structures. As a part of the installation the jacket is lowered down to the seabed from a free hanging configuration, ... -
Simulator Studies on the Effectiveness of a Collision Avoidance Display in True Motion
(Master thesis, 2011)A major concern for the navigator during a voyage is collision avoidance. The IBS (Integrated Bridge System) has a large quantity of marine traffic data available. Complicated and congested traffic may challenge the ... -
Coupling of marine riser and tensioner system
(Master thesis, 2011)A coupled model of a marine riser and a tensioner system is built. The riser is modeled using the multi-body dynamics program MSC Adams, and the tensioner system using the powerful controls and systems simulation tool, MSC ... -
Development of a DP system for CS Enterprise I with Voith Schneider thrusters
(Master thesis, 2011)A model ship named CS Enterprise 1 (CSE1) has been purchased by the Norwegian University of Science and Technology (NTNU) to be used for demonstrations and student experiments at the Marine Cybernetics Laboratory (MC ... -
Decision Models related to Ageing and Life Extension
(Master thesis, 2011)Ageing is a process in which the characteristics of a Structure, System or Component (SSC) gradually change with time or use. Several installations tied to the Norwegian petroleum industry are ageing. They have reached ... -
Prediction of ice loads of an Arctic SPAR
(Master thesis, 2011)Asubstantial amount of the world’s hydrocarbon deposits is assumed to be found in the Arctic. The Arctic region differs from other regions mainly due to the climate and presence of sea ice features. In order to minimize ... -
High energy ship collisions with bottom supported offshore wind turbines
(Master thesis, 2011)Offshore wind farming is an industry under development and involves challenges. The farms might be located close to ship trading routes. This increases the risk of ship-wind farm impact, causing economic losses, environmental ... -
The importance of added resistance and speed of ships due to waves for ships designed for slow-steaming
(Master thesis, 2011)In the recent years the greenhouse effect in the atmosphere has become much stronger because of emissions of greenhouse gases on the earth. One of these gases is CO2. This may come from combustion of fossil fuel. The ... -
Pipeline Accidental Load Analysis
(Master thesis, 2011)Ship interaction in terms of anchor hooking on a subsea pipeline has been investigated in this thesis. An attempt has been made to predict the most probable anchor interaction loads on the Kvitebjørn gas pipeline in the ... -
Interaction between bodies in a viscous flow
(Master thesis, 2011)Using the open-source CFD-solver OpenFOAM with a numerical scheme which is first order in time and second order in space, calculations of unsteady 3D flow around two cylinders in tandem arrangement at low Reynolds number ... -
System design for rapid cargo change on liquefied gas carriers
(Master thesis, 2011) -
AIS Technology as Support for the Risk Picture in Naval Transport
(Master thesis, 2011)This thesis investigates the feasibility of using AIS technology as a support for determining the risk picture in naval transport. Traffic data is gathered from the AIS interface and compared with accident data from NMD ... -
Meshfree Least Square-based Finite Difference method in CFD applications
(Master thesis, 2011)Most commercial computational fluid dynamics (CFD) packages available today are based on the finite volume- or finite element method. Both of these methods have been proven robust, efficient and appropriate for complex ... -
Mixing in the stratified interface of the Faroe Bank Channel overflow: the role of transverse circulation and internal waves
(Journal article; Peer reviewed, 2011)The overflow of cold water across the Faroe Bank Channel sill is a significant volume flux of dense water to the North Atlantic Ocean. Using observations of hydrography, current and microstructure from a 1 week cruise and ... -
Analysis and Design of Columns in Offshore Structures subjected to Supply Vessel Collisions
(Master thesis, 2011)The assessment had been conducted for shipside collision against unstiffened, inclined jacket leg segment (column). The inclined column has been modelled with horizontal-to-vertical ratio of 1/7. Two types of boundary ... -
Hydrodynamiske beregninger med bølgeoverflater
(Master thesis, 2011)Innledningsvis ble noe av det teoretiske grunnlaget for oppgaven gitt. De viktigste antagelsene var at strømningen er isotermisk og at fluidene er antatt å være inkompressible. Videre er det gått igjennom hvodan man setter ... -
Comparison study of measured stresses, and stresses from a global analysis model in an offshore structure member
(Master thesis, 2011)The first part of the thesis is related to theory of concern to the thesis and to fatigue life estimation in general. Secondly an investigation of which parameters that introduce uncertainty is investigated. And thirdly a ... -
Modeling and analysis of ship traffic by observation and numerical simulation
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:136, Doctoral thesis, 2011)The continuing losses of vessels and the ever increasing volume of cargo carried by ship marks marine traffic as a high risk activity where a single accident has the potential to incur large human, environmental and economic ... -
Mathematical Modeling for Marine Crane Operations
(Master thesis, 2011)As mathematical models for marine vessel dynamics are frequently used for several different purposes there is a need for finding ways of facilitating connection of sub models to extend these models to include various ...
