An Experimental and Numerical Investigation of the Effect of Axial Thermal Gradients in Flexible Pipes
Fergestad, Dag; Klæbo, Frank; Muren, Jan; Hylland, Pål; Grøv, Tom Are; Lange, Hans Iver; Gjøsteen, Janne Kristin Økland; Gjendal, Andreas; Melve, Bjørn; Kristensen, Claus Egeberg (ASME Digital Collection;OMAE2017-61804, Chapter, 2017-09-21)This paper discusses the structural challenges associated with high axial temperature gradients and the corresponding internal cross section forces. A representative flexible pipe section designed for high operational ... -
Early Detection of Subsurface Fatigue Cracks in Rolling Element Bearings by the Knowledge-Based Analysis of Acoustic Emission
Hidle, Einar Løvli; Hestmo, Rune Harald; Adsen, Ove Sagen; Lange, Hans Iver; Vinogradov, Alexei (Peer reviewed; Journal article, 2022)Aiming at early detection of subsurface cracks induced by contact fatigue in rotating machinery, the knowledge-based data analysis algorithm is proposed for health condition monitoring through the analysis of acoustic ... -
Fracture propagation control in CO2 pipelines: Validation of a coupled fluid-structure model
Aursand, Eskil; Dumoulin, Stephane; Hammer, Morten; Lange, Hans Iver; Morin, Alexandre; Munkejord, Svend Tollak; Nordhagen, Håkon Ottar (Journal article; Peer reviewed, 2016)Existing engineering methods to ensure fracture propagation control in natural-gas transmission pipelines have been shown to be non-applicable when dense-phase CO2 is transported. To overcome this, a coupled fluid-structure ...
