Roughness evaluation in shotcrete-lined water tunnels with invert concrete based on cases from Nepal
(Journal article; Peer reviewed, 2018)Most of the existing roughness estimation methods for water tunnels are related to either unlined or concrete/steel-lined tunnels. With the improvement in shotcrete technology, advancement in tunneling equipment and cost ... -
Round-Robin Study for Ice Adhesion Tests
(Peer reviewed; Journal article, 2024)Ice adhesion tests are widely used to assess the performance of potential icephobic surfaces and coatings. A great variety of test designs have been developed and used over the past decades due to the lack of formal standards ... -
Route Guidance Strategies for Electric Vehicles by Considering Stochastic Charging Demands in a Time-Varying Road Network
(Peer reviewed; Journal article, 2020)Electric vehicles (EVs) are being increasingly adopted because of global concerns about petroleum dependence and greenhouse gas emissions. However, their limited driving range results in increased charging demands with a ... -
Route modelling in coastal navigation for digital twins and digital platforms
(Master thesis, 2020)Denne oppgaven undersøker hvordan digital tvilling teknologi kan brukes til å ta smartere beslutninger og operere mer effektivt i kystnavigering. Forskningsspørsmålene for denne oppgaven er: (1) Hva er begrensende faktorer ... -
ROV Control System for Positioning of Subsea Modules
(Master thesis, 2014)Installation of deep water Xmas trees for subsea oil production is sometimes done by lowering the tree using one wire. Xmas trees are interfacing with other equip- ment on the seafloor and will therefore need to be positioned, ... -
ROV elektronikksylindre av kompositt til bruk ved store havdyp
(Master thesis, 2012)Sperre AS produserer i stor grad hele ROV konstruksjonen sin i aluminiumslegeringen AA6082-T6. Dette er et velegnet materiale for oppgava, men med noen mangler.Denne oppgava fokuserer på elektronikksylindrene til ROV-en, ... -
"ROV Intervention Tool Skid (RITS)": Development of a new ROV tool
(Master thesis, 2014)Most subsea installations have their own, integrated control and automation systems. In cases where this is impossible or the mechanism fails, the only unit that can handle such problems is the ROV. This makes the ROV ... -
ROV Motion Control Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:295, Doctoral thesis, 2014)This thesis is about automatic motion control systems for remotely operated vehicles (ROV). The work has focused on topics within guidance and navigation. In addition, a motion control system has been developed, implemented, ... -
ROV-basert multi-sensor verktøy for inspeksjon og overvåking av undervanns rørledning
(Master thesis, 2014)Offshore industrien bruker store ressurser på å sikre integriteten til undervannsrørledninger. Feilmekanisme i form av lekkasje vil ha direkte innvirkning på driften. Det iverksettes derfor omfattende vedlikeholdsstrategier ... -
RP-200: Design of PD pump for pumping of molasses
(Master thesis, 2008)Abstract Motivation There is, at the present time, no submerged molasses pump on the market that is designed specifically for cargo tankers. Due to this I, find it interesting to look into the possibilities of installing ... -
RSW Systems with CO2 as Refrigerant: Testing of new system solutions for sea water coolers
(Master thesis, 2009)In a refrigerated seawater (RSW) system using carbon dioxide (CO2) as the refrigerant, a variable bypass valve was installed in front of a suction gas heat exchanger (SGHX). A simulation tool was developed and utilized to ... -
Rubber contact mechanics: adhesion, friction and leakage of seals
(Journal article; Peer reviewed, 2017)We study the adhesion, friction and leak rate of seals for four different elastomers: Acrylonitrile Butadiene Rubber (NBR), Ethylene Propylene Diene (EPDM), Polyepichlorohydrin (GECO) and Polydimethylsiloxane (PDMS). ... -
Rubber friction: The contribution from the area of real contact
(Journal article; Peer reviewed, 2018)There are two contributions to the friction force when a rubber block is sliding on a hard and rough substrate surface, namely, a contribution Fad = τf A from the area of real contact A and a viscoelastic contribution Fvisc ... -
Rubble Macro-porosity of Level Ice Accumulation on Wide Sloping Offshore Structures
(Master thesis, 2018)1. Ice block size distribution have significant effect on rubble porosity. The length and thickness of the ice blocks in the ice rubbles is measured with image processing approach. Correlation analysis shows that the ice ... -

Running fracture in a H2 pressurized pipeline: characterization and simulation of dynamic ductile fracture in two X65 pipeline steels
(Master thesis, 2011)Long running fractures in pipelines pose great danger to humans, as well as leading to significant economical losses. Current methods of predicting crack arrest require cumbersome re-calibration when new pressurized media ... -
Running fracture in a H2 pressurized pipeline: from small scale material testing to full scale experiments and simulations
(Master thesis, 2011)Cracks should never occur in gas transmission pipelines. Cracks in pipelines are the most critical pipe failure mode and the cost of such an event is always huge depending on when and where it happens. Human life and nature ... -
RUNOFF FORECASTING AND DEVELOPMENT OF AN OPERATIONAL PRODUCTION PLANNING MODEL FOR THE BUI HYDROPOWER PLANT IN THE BLACK VOLTA, GHANA
(Master thesis, 2015)The Bui Hydropower reservoir faces a situation of excess inflow in the rainy season and very little inflow in the dry season. This situation has prompted a major focus on the development of an accurate inflow forecasting ... -
