The effect of local wake model on collision probability for risers subjected to current and random waves
(Journal article; Peer reviewed, 2018)The present paper provides a method to estimate the clearance between two flexible risers in tandem arrangement by taking into account the hydrodynamic wake interference when subjected to a current flow and a combined ... -
The Effect of Low Temperatures on Energy Dissipation in Accidental Collisions on Marine Structures
(Master thesis, 2017)The effect of low temperatures on impacts between ships and icebergs have been investigated. A material model developed by Woongshik Nam has been used for modelling the effect of brittle fracture. To test the model, an ... -
The Effect of Turbulence Model on the Response of a Large Floating Wind Turbine
(Chapter; Peer reviewed, 2017)The wind turbine design standards advise choosing one of two recommended turbulence models for load simulations of offshore wind turbines. The difference in fatigue loads for the two turbulence models is relatively small ... -
The effect of waves on engine-propeller dynamics and propulsion performance of ships
(Journal article, 2016)This paper investigates the effect of waves on the propulsion system of a ship. In order to study the propulsion in different wave conditions, a procedure for wake estimation in waves has been implemented. A clear drop in ... -
The Effect of Waves on Marine Propellers and Propulsion
(Doctoral theses at NTNU;2017:106, Doctoral thesis, 2017)Ship design is evolving around ever-increasing market demands in quest of competitive and cost-effective solutions. The global increase of shipping activities has raised concerns regarding the environmental impact of sea ... -
The effects of coherent structures on the global response of floating offshore wind turbines
(Journal article; Peer reviewed, 2018)The global dynamic response of floating wind turbines is commonly simulated using aero‐hydro‐servo‐elastic tools that consider numerically generated wind files as input. Based on the guidelines given in existing standards, ... -
The Effects of Human Fatigue on Risk at Sea
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:340, Doctoral thesis, 2014)The main purpose of this PhD thesis is to improve the current international knowledge pool regarding the circumstances in which human fatigue develops on board a vessel and its effect on the probability of maritime grounding ... -
The Effects of Surface Waves and Submergence on the Performance and Loading of a Tidal Turbine
(Chapter; Peer reviewed, 2017)Tidal energy has the advantages of high predictability, high energy density, and limited environmental impacts. As tidal turbines are expected to be used in the most energetic waters where there might be significant waves, ... -
The Efficiency of a Mewis Duct in Waves
(Master thesis, 2013)In this thesis, the efficiency of a Mewis Duct in waves has been investigated with the use of model tests in the large towing tank at MARINTEK in Trondheim. A ?load-varying? self-propulsion method was used, allowing for ... -
The Environmental Impact of Capacity Utilisation on RoRo Shipping - A Life Cycle Assessment
(Master thesis, 2016)The focus on reducing global emissions has increased over the last decades, and has resulted in stricter environmental requirements for the shipping industry. New regulations focus on reducing the pollution of ships to sea ... -
The feasibility of all-electric coastl fishing vessels based on AIS data
(Master thesis, 2020)For å redusere utslepp og stoppe aukinga av den globale temperaturen, handling er nødvendig. Ein teknologi som kan erstatte forbrenningsmotoren som er brukt i dag, er batteriteknologi. Tal frå Sintef, seier at det er ein ... -
The Fishing Vessel - Optimising Design and Functionality Based on Profit Optimisation of Fishery Selection, Routing and Change of Equipment Configuration
(Master thesis, 2020)Norsk fiskerinæring har de siste årene hatt en jevn økonomisk vekst, men en øvre grense på hvor mye havområdene tåler har blitt nådd. Norske myndigheter har derfor gitt norske fartøy større muligheter til å ta i bruk nye ... -
The harmonic polynomial cell method for moving bodies immersed in a Cartesian background grid
(Chapter; Peer reviewed, 2015)In numerical simulations with moving bodies, and often with complex geometries, generation of high-quality body-fitted grids is a cumbersome and time-consuming task. An alternative is to use a fixed (Cartesian) background ... -
The impact of a passive tuned mass damper on offshore single-blade installation
(Journal article; Peer reviewed, 2018)Single-blade installation is a method suitable for the installation of blades on large wind turbines. For single-blade installations on offshore monopile-type wind turbines, a jack-up vessel is often involved, and each ... -
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 ... -
The Importance of Friction Reduction in Boundary Layers
(Master thesis, 2019)The modification of boundary layers for the purpose of drag reduction and overall propulsive efficiency for marine vehicles is an interesting concept, one which has been studied through swimming fish, which can alter the ... -
The influence of fish on the mooring loads of a floating fish farm
(Chapter, 2015)The influence of fish on the mooring loads of a floating fish farm is studied numerically and experimentally. Two experimental series were conducted. One case was model tests with artificial fish. Nine rigid fish models ... -
