Bølgekompensering under boring med RamRig: Modellering og regulering
(Master thesis, 2007)Sammendrag: Hivkompensering kan deles inn i passiv, aktiv og semiaktiv kompensering utifra i hvilken grad det benyttes et aktivt pådrag for å kompensere for hivet. Hivkompenserig kan gjøres på forskjellige måter. Toppmontert ... -
Developing Embedded Control System Platform using Atmel AVR32 Processor: Using Rapid Prototyping with Matlab Real-Time Workshop
(Master thesis, 2007)AVR32 is a new processor architecture made by Atmel Norway, and in this thesis it has been used to make a control system platform. The hardware used in this platform is the STK1000, an AVR32 development board and an I/O-card. ... -
Modeling and Simulation of Anti-slug Control in Hydro Experimental Multiphase Flow Loop
(Master thesis, 2007)Handling slug flow is a matter of necessity in the oil and gas industry. Large slugs cause problems at the production platform by overfilling the first stage separator leading to poor separation and pressure increase, which ... -
Design of an Electric X-mas Tree Gate Valve Actuator
(Master thesis, 2007)The increasing need for more energy in the world is making the oil companies search for hydrocarbons in deeper water and with longer distances between the well and platform(step-out) never experienced before. Current systems ... -
Predictive Control of Residue on Evaporation: Control Structure Design
(Master thesis, 2007)Summary -
Sensor Integration for Nonlinear Navigation System in Underwater Vehicles
(Master thesis, 2007)This thesis deals with three methods for integrating measurements from different sensors for an underwater vehicle. The sensors that were used are inertial measurement unit (IMU), Doppler velocity log (DVL), Hydro- acoustic ... -
Modelling Simulation and Control of Fixed-wing UAV: CyberSwan
(Master thesis, 2007)This report treats modelling, simulation and control of a fixed-wing aircraft, including implementation of a Aircraft Flight Control System (AFCS). The design and construction of a suitable airframe (design og konstruksjon ... -
Stability Analysis of Nonlinear Attitude Determination and Control Systems
(Master thesis, 2007)This report describes the modelling and performance of an attitude determination and control system (ADCS) for a small satellite in lunar orbit. The focus is on stability analyses of each of the components in the system, ... -
Functional Testing of Valves: A study of possible improvements that can be achived by Partial Stroke Testing at Statoil Kollsnes
(Master thesis, 2007)Summary and Conclusion Emergency Shutdown (ESD) valves and High Integrity Pressure Protection System (HIPPS) valves are final elements in Safety Instrumented Systems. Proof or functional testing are performed at specific ... -
Instrumentering av autonomt ubemannet fly: CyberSwan
(Master thesis, 2007)Målet med CyberSwan er å lage en generell plattform for et autonomt ubemannet fly. Gjennom arbeidet som er beskrevet i denne rapporten er det kommet frem til et egnet instrumenteringsplattform for CyberSwan. Med ... -
Control system for rotifer production
(Master thesis, 2007)Rotifers are used extensively as start feed for many cultured marine fish species and commercial size hatcheries require stable daily supply of high quality rotifers of substantial volumes. This is often done relying on ... -
COTS based Control System for Subsea
(Master thesis, 2007)This thesis looks into different topics regarding the use of Commercial off The Shelf (COTS) hardware and software for subsea control systems. COTS basically means every product which is commercially available. The idea ... -
Numerical Modelling and Model Reduction of Heat Flow in Robotic Welding
(Master thesis, 2007)The project includes a numerical model of heat flow in robotic welding. The modelling is done in finite element method, and afterwards exported to Matlab where the model will be linearized and model reduced. The ultimate ... -
Development of an Electro-Mechanical model for Simulation of Stability in Wind/Diesel/Electrolyser Systems
(Master thesis, 2007)This thesis is about DC voltage regulation in a wind-hydrogen stand alone power system. A base case in MatLab/Simulink was expanded to include an electrolyser with power electronics and control electronics. It was decided ... -
Pipeline Liquid Control using Nonlinear MPC and OLGA: Optimal Utilization of Available Liquid Buffer Volume during Pipeline Transients
(Master thesis, 2007)Pipelines with multiphase flow will exhibit large and highly nonlinear liquid rates during transients caused by changes in production rate. This requires either a large separator (slug catcher) downstream, capable of ... -
Estimering av TNS-parametre og -ytelse
(Master thesis, 2007)Undervannsbåter er avhengige av et treghetsnavigasjonssystem (TNS) for å kunne beregne egen posisjon når de er neddykket. Denne oppgaven vil se nærmere på et skrogfast TNS som er i bruk på de norske undervannsbåtene av ... -
