Feasibility Study of the “Launch and Forget” Installation Method for Deep Water Marine Operations
(Master thesis, 2019)Formålet med denne masteroppgaven er å bidra med å utforske gjennomførbarheten i metoden "Launch \& Forget", ved å undersøke egenskapene til en modellskala brønnramme når den beveger seg nedover i vannkolonnen. Eksperimenter ... -
Feasibility Study on Active Wave Compensation of ROV - Modelling, Analysis and Simulation
(Master thesis, 2014)The aquaculture industry is using remotely operated vehicles (ROVs) for maintenance tasks on fish farms. These tasks include, among others, washing of the netpen and visual inspections. These are tedious tasks, and it would ... -
Feil-tolerant dynamisk posisjonering for den autonome testplattformen ReVolt
(Master thesis, 2019)Eit feiltolerant kontrollsystem for dynamisk posisjonering av DNV GLs modellskip ReVolt har vorte utvikla, med mål om å kunne diagnostisere og handtere sensor- og aktuatorfeil som kan oppstå. Delar av implementasjonen ... -
Fidelity of Cyber-Physical Empirical Methods Application to the active truncation of slender marine structures
(Doctoral theses at NTNU;2018:405, Doctoral thesis, 2018)Cyber-physical empirical methods (CPEMs) are empirical methods in which a dynamical system under study is partitioned into physical and numerical substructures. While the numerical substructures are described by validated ... -
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 a Protective Cover Subjected to Impact from a Dropped Container and Comparison of Implicit and Explicit Solvers
(Master thesis, 2024)Denne masteroppgaven ved Norges teknisk-naturvitenskapelige universitet utforsker den dynamiske responsen til marine strukturer ved høyenergi-sammenstøt ved hjelp av Finite Element Analysis (FEA). Fokuset ligger på effekten ... -
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
