A Survivability Analysis of Two Floating Offshore Wind Turbines in Intact and Damaged Conditions
(Master thesis, 2023)Vindenergi identifiseres som en del av løsningen for å tilby tilstrekkelig bærekraftig, trygg og sikker fornybar energi. Ettersom det er begrenset med passende områder på land eller nær kysten, er det et behov for flytende ... -
A techno-economic assessment of operating a deep-sea hydrogen-driven chemical carrier.
(Master thesis, 2021)For å møte FNs mål for bærekraftig utvikling så fokuserer stater og internasjonale organisasjoner på å gi insentiver til selskaper for å redusere utslippene sine. Et effektivt virkemiddel er å knytte utslippene opp mot ... -
A Temperature-dependent Model of Ratio of Specific Heats Applying in Diesel Engine
(Master thesis, 2017)Rate of heat release is a standard tool when engineers tune and develop new engines. The ratio of specific heats $\gamma$ is considered an essential parameter for achieving accurate rate of heat release calculation as it ... -
A Winkler Model for the Seismic Analysis of Monopile Foundations - An Exploratory Study on the Modelling of Soil-Structure Interaction during Earthquakes
(Master thesis, 2018)The growing interest in the development of offshore wind farms in seismic active areas demands a better insight into the requirements earthquakes impose on the design of wind turbine foundations. The complexity of the ... -
Accident Frequency Analysis for the Stad Ship Tunnel
(Master thesis, 2018)The objective of this thesis is to find a suitable method to update previous risk analyses on the projected fairways of the Stad Ship tunnel, which is planned to reduce coastal traffic exposure to severe weather in the ... -
Accidental Drop of Slender Cylindrical Bodies - A Numerical and Experimental Study of Velocity and Trajectory of Cylinders Falling Through Water
(Master thesis, 2018)The oil and gas industry is continuously working to improve safety and minimise risk. Numerous offshore activities involve risks that may lead to accidents with serious consequences. The risk of accidental dropped objects, ... -
Accidental Impact Resistance of non-disconnectable bouy type FPSO
(Master thesis, 2014)The surroundings of offshore structures consist of many components controlled by nature, but also some that are managed by people- ships. Due these factors, ship collisions are a constant threat to offshore installations ... -
Active Magnetic Radial Bearings Applied To Rotor Dynamics
(Master thesis, 2014)This thesis considers the development of a mathematical expression for actively controlled magnetic bearings and their influence on a flexible shaft with two disks supported by two bearings. Active magnetic bearings are a ... -
Actuation moments for hydrofoil flaps
(Master thesis, 2018)The following thesis investigates how the computer software STAR-CCM+ and Xfoil are used to determine the hydrodynamic loads on the two foil profiles EP- PLER E817 and NASA/LANGLEY LS(1)-0417 (GA(W)-1) with trailing ... -
Actuation of loads by using fans, and application to hydrodynamic testing
(Master thesis, 2023)Denne masteroppgaven hadde som mål å designe, bygge og teste et eksperimentelt oppsett ved hjelp av en viftebasert belastningsmetode for å påføre flere laster. Målet var å se på muligheten for å påføre aerodynamiske laster ... -
Adaptive Control of Underwater Snake Robot
(Master thesis, 2019)Ideen om bruk av slangeroboter til undervannsoperasjoner handler om dens fleksibilitet og fordelaktige evne til å bevege seg rundt og inne i installasjoner under vann. Slangeroboter er antatt mer egnet for komplekse ... -
Adaptive Stress Testing applied to a Maritime Object Detection System
(Master thesis, 2022)Med den stadig større rollen autonome systemer tar i den moderne verden, følger et stort fokus på verifisering av tilstrekkelig trygghet. Grundig verifisering av et autonomt system krever testing på alle nivåer av systemet, ... -
Adaptive Stress Testing of Situational Awareness for an Autonomous Passenger Ferry
(Master thesis, 2022)Maritime Autonomous Surface Ships (MASS) introduserer et nytt nivå av kompleksitet til marine kontrollsystemer. Zeabuz er et oppstartsselskap fra NTNU som jobber med MASS og som har som mål å utvikle autonome urbane ... -
Adaptive Vertical Motion Control System for a Surface Effect Ship
(Master thesis, 2018)In this thesis, an adaptive controller is developed, with the purpose of actuating the pressure of the air cushion of a Surface effect ship (SES), as means of reducing wave induced vertical vessel motions. The rise in the ... -
Added ship resistance from headboxes and transverse tunnels in full scale CFD
