3D robot vision using multiple cameras
(Master thesis, 2016)3D computer vision has in recent years become more popular in regards to robotic vision systems. This thesis looks into the possibility of using a multiple 3D camera setup for robotic vision. The approach is to reconstruct ... -
A modular CNC machine
(Master thesis, 2018)This report assesses different design solutions for a modular CNC-machine with capabilities for additive production, CNC-milling and laser engraving. The design is meant for a target group where hobbyists and home-enthusiasts ... -
A Study of a Subsea Chemicals Storage & Injection-Station
(Master thesis, 2017)Total and Doris have announced that they want to challenge the way of thinking of how to supply subsea field developments with chemicals. With a Subsea Chemicals Storage & Injection-station (SCS&I) the chemicals are injected ... -
Alternative Methods for Tubing Removal
(Master thesis, 2014)When the production from a well is no longer profitable, the options are to either permanently plug and abandon (P&A) the well, or to re-use the slot by plugging the original well and sidetrack a new wellbore (slot recovery). ... -
Analysis of Compact Separation Systems and Experimental Study of Centrifugal Separation in Helically Coiled Pipes
(Master thesis, 2015)The offshore petroleum industry is experiencing challenges as exploration and production are forced towards remote and deep reservoirs, combined with high cost-efficiency demands. Topside facilities struggle with limited ... -

(Master thesis, 2015) -
Assessment of Welded Structural Joints in Subsea Module Frames
(Master thesis, 2018)In structural design, optimization is a keyword by means of selecting the best design within the boundary conditions provided by a given system. Structural engineering is a well-known discipline and there have been conducted ... -
Bruk av robotsyn for griping av et objekt i bevegelse
(Master thesis, 2015)Målsetningen for dette prosjektet var å få en manipulator til å gripe et objekt i bevegelse ved bruk av robot syn. To deteksjonsmetoder ble sammenlignet og implementert i et kamerabasert styringssystem i robotcellen ved ... -
Coiled tubing drilling system placed on the seabed
(Master thesis, 2016)In recent years, the demand for more cost effective solutions within the oil industry has been huge. Low oil prices mean that innovation and new intelligent solutions are required to get profit. The focus is on reducing ... -
Compact Separation - Concept Study - Experimental and Simulation Study of Oil-Water Multiphase Flow in Helically Coiled Pipe
(Master thesis, 2016)This master thesis is written as part of a SUBPRO project whose long term goal is to identify multiphase flow separation performance of a helically coiled pipe and determine if it s viable for further industrial development. ... -
Computational Study of Hydraulic Accumulators
(Master thesis, 2018)The scope of this project is to make a CFD model to be used for getting a better understanding of accumulator discharge. To be able to establish the models credibility is there a need for validation of the models developed. ... -
Corrosion properties of AA5083 and AA6082 in seawater - effect of temperature, pH and potential
(Master thesis, 2016)Aluminium is an interesting material for use in subsea structures due to its low weight. So called corrosion resistant aluminium alloys from the Al-Mg (5xxx)- and Al-Mg-Si (6xxx) series have been used for many years in ... -
Crane Maintenance in the Era of Industry 4.0
(Master thesis, 2017)Today s companies are facing a series of challenges, experiencing difficulty in increasingly specialized and competitive markets and demanding restructuring processes. The industry needs countermeasures to prove their place ... -
Design of Compact Separator Laboratory
(Master thesis, 2016)Most of the easily accessible offshore oil and gas resources have been developed. As a result of this, subsea production and processing has over the last decade been regarded as the future of the offshore oil and gas ... -
