Field Measurements of Inhomogeneous Wave Conditions in Bjørnafjorden
(Journal article; Peer reviewed, 2018)Due to the complex topography in a fjord, wave conditions differ from those of ocean waves. In this study, characteristics of wave conditions in the Bjørnafjorden in Hordaland County, Norway were thoroughly investigated ... -
Field Report: Exploring Fronts with Multiple Robots
(Chapter, 2018)This paper presents a report from a cruise onboard the R/V Falkor oceanographic vessel from the Schmidt Ocean Institute. The goal of this cruise was to demonstrate a novel approach to observe the ocean with multiple ... -
Finite element analysis of marine umbilical
(Master thesis, 2011)Background: Marine umbilicals play a vital role in oil and gas production fields. The oil and gas industry is in constant change, as the resources in the reservoirs are ever decreasing. Today oil and gas exploration takes ... -
Finite element cable-model for Remotely Operated Vehicles (ROVs) by application of beam theory
(Journal article, 2018)Increasing autonomy, efficiency and safety for Remotely Operated Vehicles (ROVs) is crucial for future subsea operations and requires accurate models for optimal control, operations and design. This involves precise modeling ... -
Finite Element Modeling and Structural State Estimation of a Bottom Fixed Offshore Wind Turbine
(Master thesis, 2015)As a path to combine the world s growing energy demand with renewable green energy, in- creased use of offshore wind turbines has been seen as a viable solution. Unfortunately, the remote location and rough environment for ... -
Finite-time Backstepping of a Nonlinear System in Strict-feedback Form: Proved by Bernoulli Inequality
(Peer reviewed; Journal article, 2020)In this paper, we propose a novel state-feedback backstepping control design approach fora single-input single-output (SISO) nonlinear system in strict-feedback form. Rational-exponent Lyapunovfunctions (ReLFs) are employed ... -
First hyperspectral imaging survey of the deep seafloor: High-resolution mapping of manganese nodules
(Journal article; Peer reviewed, 2018)Hyperspectral seafloor surveys using airborne or spaceborne sensors are generally limited to shallow coastal areas, due to the requirement for target illumination by sunlight. Deeper marine environments devoid of sunlight ... -
The fish ability to accelerate and suddenly turn in fast maneuvers
(Peer reviewed; Journal article, 2022)Velocity burst and quick turning are performed by fish during fast maneuvers which might be essential to their survival along pray–predator encounters. The parameters to evaluate these truly unsteady motions are totally ... -
Fish Escape and Models to Assess Influential Factors
(Master thesis, 2019)Denne avhandlingen undersøker problemer relatert til fiskerømming og sikkerhetsstyring i havbruk. Grunnlaget denne avhandlingen bygger på er en litteraturstudie av akvakultur og to databaser som inneholder historisk ... -
Fish-Inspired Propulsion Study: Numerical Hydrodynamics of Rigid/Flexible/Morphing Foils and Observations on Real Fish
(Doctoral theses at NTNU;2023:7, Doctoral thesis, 2023)Many swimming fishes in nature have been endowed with high hydrodynamic efficiency and performance, such as low resistance, high speed, and good maneuverability, both when swimming individually and in groups, i.e., using ... -
Fishtailing behaviour of single point moored floating wind turbines
(Master thesis, 2020)The demand for clean energy is growing rapidly and the offshore wind industry is moving from shallow water to an intermediate depth. When the water is deep enough, the floating wind turbines are more feasible than the ... -
Fiskebåten som fremtidig arbeidsplass - Sluttrapport fra 3-årig tverrfaglig forskningsprosjekt rettet mot sikkerhet og arbeidsforholdene i ulike fartøy- og flåtegrupper
(SINTEF Rapport;, Research report, 2005)Personulykkesstatistikken viser at fiskeriet fortsatt må regnes som et av de mest risikofylte yrker i Norge. Det er i dette prosjektet spesielt gjort undersøkelser knyttet til arbeidsoperasjoner i fiskeflåten som er ... -
Flapping Foil Propulsion for Conventional Ships
(Master thesis, 2017)Feasibility of flapping foil propulsion was discussed with respect to design in the project thesis. The study showed that flapping foil propulsion is feasible for conventional ships, but the performance predictions were ... -
Fleet and Scheduling Optimization for Offshore Floating Wind Installation under Impact of Weather
(Master thesis, 2021)Elektrisitet som er produsert fra fornybare kilder vokser raskt ettersom verden må gå vekk fra fossile energi ressurser for å oppnå klima målet på 2 grader. For å oppnå klima målet, må det skje en kraftig overgang fra ... -
Fleet Scheduling of Service Vessels used in a more exposed Norwegian Aquaculture Industry
(Master thesis, 2017)This thesis studies a maritime transportation problem for service vessels used in the Norwegian aquaculture industry. We create an optimization model which try to find the most efficient fleet size and mix and associated ... -
Fleet Size and Mix in the Norwegian Aquaculture Sector - A stochastic fleet renewal problem with an uncertain future
(Master thesis, 2017)The aquaculture sector in Norway aims to increase the production five times by 2050. For this aim to be reached it is likely that new solutions relating to the future service needs of the sector need to be developed. To ... -
