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 ... -

(Bachelor thesis, 2022)Denne rapporten svarer på en prosjektoppgave gitt av Møre og Romsdals fylkeskommune. Oppgaven omfatter planlegging og detaljprosjektering av en firearmet rundkjøring på fylkesveg 60, i Sykkylven kommune. Det skal i tillegg ... -
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 ... -

Runway Operability under Cold Weather Conditions. Tire-pavement friction creation by sand particles on iced pavements, and non-contacting detection of sand particles on pavements
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:215, Doctoral thesis, 2007)Airports that operate under cold weather conditions face major challenges in ensuring that runways, taxiways and aprons provide sufficient tire-pavement friction to the operating aircraft. This thesis is motivated by two ... -
Rupture analysis of rubber in the presence of a sharp V-shape notch under pure mode-I loading
(Journal article, 2018)The rupture behavior of styrene-butadiene rubbers (SBR) in the presence of a V-shape notch is investigated for the first time both experimentally and theoretically. In the experiments, V-notched samples of SBR are tested ... -
