Vortex Induced Vibrations in Fish Farm Structural Elements
(Master thesis, 2015)Norway produces over 14 million meals of salmon every day. This corresponds to an annual value of close to 40 billion NOK. The world s continuous population increase will require a substantial increase in food production. ... -
Vortex induced vibrations of free span pipelines
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:106, Doctoral thesis, 2009)Pipelines from offshore petroleum fields must frequently pass overareas with uneven seafloor. In such cases the pipeline may havefree spans when crossing depressions. Hence, if dynamic loads canoccur, the free span ... -
Vortex Induced Vibrations of Marine Risers
(Master thesis, 2012)SummaryThis Master s Thesis goal is to present fundamental physical aspects of Vortex Induced Vibrations (VIV) of marine risers, and outline methods for suppression of VIV. Main emphasis has been given to the use of strakes, ... -
Vortex Induced Vibrations of Pipelines With Non-Linear Seabed Contact Properties
(Chapter; Peer reviewed, 2016)A promising time domain model for calculation of cross-flow vortex induced vibrations (VIV) is under development at the Norwegian University of Science and Technology. Time domain, as oppose to frequency domain, makes it ... -
Vortex Induced Vibrations of Slender Catenary Structures
(Master thesis, 2015)A wide range of offshore science and engineering applications utilize slender catenary-shaped structural elements in their design. These applications include moorings and steel catenary riser designs. The susceptibility ... -
Vortex Induced Vibrations of Slender Marine Structures
(Master thesis, 2013)The main objective of this thesis is to study the behaviour of slender marine structures exposed to vortex induced vibrations (VIV). Especially the interaction between active response frequencies is important. This is done ... -
Vortex Induced Vibrations Of Slender Marine Structures: Inverse Analysis
(Master thesis, 2013)With the development of the offshore engineering and the increasing of water depth, VIV (vortex induced vibrations) becomes a big challenge of the design of slender marine structures. In engineering field, we use some ... -
Vortex Induced Vibrations on an ''Artificial Seabed'' for Support of a Floating Bridge
(Master thesis, 2015)The engineering company Reinertsen is planning a floating bridge with tunnel that will go across the Sognefjord. Reinertsen has designed what they call an "artificial seabed" to be used for anchoring of the floating bridge. ... -
Vortex Induced Vibrations Response Evaluation
(Master thesis, 2010)In designing oil and gas pipelines, many aspects should be considered. One of those aspects is fatigue damage due to time varying stresses in the pipe. The stresses in the pipe may be caused by dynamic loads and the most ... -
Vortex interaction in the wake of a two- and three-bladed wind turbine
(Peer reviewed; Journal article, 2020)The vortex interaction in the wake behind a two- and three-bladed model scale wind turbine is investigated. The two rotors have equal solidity, and produce similar power and thrust at the design tip speed ratio. Phase-averaged ... -
Vortex system around a step cylinder in a turbulent flow field
(Peer reviewed; Journal article, 2021)The vortex system around the step surface of a step cylinder with a diameter ratio D/d=2 at Reynolds number (ReD) 3900 was investigated by directly solving the three-dimensional Navier–Stokes equations. Formation mechanisms ... -
Vortex-induced vibrations of a vertical riser with time-varying tension
(Journal article; Peer reviewed, 2017)Numerical simulations of a vertical tensioned riser in a sheared flow are performed, where the riser top end oscillates sinusoidally in the vertical direction. The oscillating top-end motion causes tension variations and ... -
VR-Modelling of Data from "Norway Digital" in Combination with other 3D Models
(Master thesis, 2014)The purpose with this master thesis was to use new released data from the Norwegian Mapping Authority to makea virtual world that can be looked at with or without Oculus Rift. In addition, existing 3D models of buildingscreated ... -
Vugge-til-port livsløpsanalyse av boligene Giske, Tafjord og Faro
(Bachelor thesis, 2022)Som en stor klimapåvirker, har byggenæringen et stort ansvar når det kommer til videre utvikling. Det å ta klimabeviste materialvalg vil være en essensiell del av industriens reduksjon i klimagassutslipp. For å nå de globale ... -
Vulnerability of Transportation Networks to Earthquakes
(Master thesis, 2010)Lifelines and Transportation Networks, which convey food, water, fuel, energy, information, and other materials necessary for human existence and functioning, are among the most crucial development indicators for any nation. ... -
Vurder og modeller den fremtidige effekten av klima på den hydrauliske kapasiteten til avløpsnettet - Case Bergen
(Master thesis, 2018)Klima i Norge vil endre seg i tiden som kommer. Det er derfor viktig å tilpasse infrastruktur og bebyggelse mot en endring i nedbørshendelser for å sikre en trygg transport av nedbør fra nedslagsfeltet til resipienten for ... -
Vurdering av 4D planlegging og VR
(Bachelor thesis, 2021)SAMMENDRAG Digitalisering er blitt sett på som nøkkelen til å løse mange problemstillinger i bygge- og- anleggsbransjen. Vår oppgave, som forhåpentligvis bidrar til økt digitalisering, handler om å undersøke effekter og ... -
Vurdering av basalt- og stålfibres effekt og mekaniske egenskaper i jetpeler
(Master thesis, 2012)Denne masteroppgaven er en eksperimentell studie av en selvkomprimerende konstruksjonsbetong (styrkeklasse B35) med antiutvaskingsegenskaper armert med enten basaltfiber (monofilament) eller stålfiber. Formålet med oppgaven ... -
