Modelling and Control of Coalescence Based Gravity Separators in a Subsea Separation System - with Models of Produced Water Treatment
(Master thesis, 2018)Subsea separation of well fluids is a way to reduce the cost of topside processing, and to simplify and reduce the export of products. Subsea separation consist of bulk separators and purifiers, to separate the multi-phase ... -
Modelling and Control of Dry and Wet Gas Compressors
(Master thesis, 2017)Performing gas compression subsea is an important component for future realisation of complete subsea processing facilities. Gas compressors operating with raw well fluids, categorised as wet gas, enables an increase in ... -
Modelling and control of fluid flows and marine structures
(Dr. ingeniøravhandling, 0809-103X; 2002:45, Doctoral thesis, 2002)The contributions of this thesis fall naturally into two main categories: Part I: Feedback control of fluid flows, and; Part II: Modelling and control of marine structures. Main Con tributions of Part I Part I presents ... -
Modelling and Control of High Performance Medium Voltage Drives: - Simulation and analysis of the Programmed Modulation strategy
(Master thesis, 2012)In the master thesis the concept of Programmed Modulation is investigated for motor drives with Three-Level NPC inverter. Programmed Modulation operates with pre-calculated PWM switching-patterns, which enables the facility ... -
Modelling and control of horizontal gravity separator - Demulsification of Oil-Water Interface
(Master thesis, 2018)The project involves evaluation of the performance of crude-oil and water separation in an horizontal gravity separator. It considers the effect of crude-oil and water emulsion formation and subsequently the demulsification ... -
Modelling and control of obstacle-aided snake robot locomotion based on jam resolution
(Journal article; Peer reviewed, 2009)A snake robot can traverse cluttered and irregular environments by using irregularities around its body as push-points to aid the propulsion. This characteristic feature of snake locomotion, denoted obstacle-aided locomotion, ... -
Modelling and Control of Offshore Ploughing Operations
(Master thesis, 2007)Summary: In this thesis work, mathematical models required to simulate an offshore ploughing operation has been derived. This includes a surface vessel model, a model of the plough and its friction force due to seabed ... -
Modelling and Control of Six-Phase Induction Motor Drive
(Master thesis, 2012)Multiphase machines are of interest to be applied in electric ship propulsion, where increased power ratings, reliability of operation, redundancy and efficiency are required. The study of modelling and control of multiphase ... -
Modelling and Control of Snake Robots
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:2, Doctoral thesis, 2008)Snake robots have the potential of contributing vastly in areas such as rescue missions, fire-fighting and maintenance where it may either be too narrow or too dangerous for personnel to operate. This thesis reports novel ... -
Modelling and control of submerged-arc ferrosilicon furnaces
(Doktoravhandlinger ved NTNU, 1503-8181; 1992:83, Doctoral thesis, 1992) -
Modelling and Control of the Secondary Combustion Chamber in an Energy from Waste Plant
(Master thesis, 2012)Thermal conversion of municipal and industrial waste is an environmentally friendly way to recover energy from waste. There are many governmental requirements regarding air emissions from such processes. A tight control ... -
Modelling and Control of Thruster Assisted Position Mooring System for a Semi-submersible: Analysis and Model Testing
(Master thesis, 2014)For harsh weather, nonlinear effects dominate the dynamics to a larger extent than for calm weather. The low frequency dynamics of a moored vessel are excited by second order wave drift forces. To counteract the low-frequency ... -
Modelling and control of underwater inspection vehicle for aquaculture sites
(Master thesis, 2012)Underwater vehicles such as AUVs and ROVs with hovering capabilities is a promising method for inspection of net integrity in large scale, sea based, salmon farms. The location of the salmon farms cause underwater vehicles ... -
Modelling and Control of Wave-to-Wire Model of Point Absorber Wave Energy Converters (WECs)
(Master thesis, 2019)Bølger har et stort potensial, da rundt 10% av verdens strømforbruk kan leveres fra bølgeenergi. Dette gir en unik mulighet til å bringe mer fornybar energi inn i verden ved bruken av bølgeenergiomformere (WEC). WEC-er sin ... -
Modelling and design of Pre/post tensioned reinforced concrete floaters of FOWTs against ship collisions
(Master thesis, 2024)Utviklingen av flytende offshore vind turbiner er nødvendig for den økende etterspørselen av bærekraftig energi. Fremtidens vindparker kan ligge i mer åpne havområder, og utsettes for mer krevende driftsforhold. Det kreves ... -

Modelling and dynamic analysis of a semi-submersible floating vertical axis wind turbine
(Doctoral thesis at NTNU;2015:89, Doctoral thesis, 2015)Wind turbines are mainly classified into horizontal axis wind turbines (HAWTs) and vertical axis wind turbines (VAWTs) based on different orientation of their axis of rotation. Ever-increasing demand for energy boosts ... -
Modelling and estimation of ocean wave induced error in pressure measurement
(Master thesis, 2017)Underwater vehicles use pressure sensors to measure depth. These measurements are subjected to noise from ocean waves. To reduce the impact of the wave induced noise, an estimator algorithm is applied to the measurements. ... -
