A comparative study on the free vibration characteristics of submerged pipe structures
(Master thesis, 2023-06-01)This thesis investigates the free vibration characteristics of submerged pipe-like structures using multiple added mass approaches. Traditional methods rely on constant added mass factors, which may lack accuracy for complex ... -
A Computational and Experimental Study of the Wave Load on a Horizontal Cylinder
(Master thesis, 2022-06-01)Denne studien tar sikte på å undersøke hvordan endring av bølge- og strømningsparametre påvirker bølgebelastningen på en delvis nedsenket sylinder, plassert horisontalt og på tvers mot bølgene i en fast posisjon. En 2D- ... -

Design og anvendelse av en eksperimentell hydrofoil testrigg
(Master thesis, 2021-01-29)I dette masterprosjektet designes og konstrueres en eksperimentell testrigg for hydrofoiler. For å undersøke testriggens yteevne benyttes den godt dokumenterte foilen NACA0018 som testobjekt. Preliminære eksperimentelle ... -
Digital twin of a hydraulic accumulator for virtual detection of subsea leaks
(Master thesis, 2019-06-14)In cooperation with OneSubsea, this thesis investigates the reasons behind a sudden pressure drop occurring in hydraulic systems during operation of hydraulic accumulators. The thesis also addresses the challenge of detecting ... -
Eksperimentell undersøkelse med modellturbin under konstant slep og bølgebelastning
(Master thesis, 2023-06-01)Med økende behov for fornybar energi forventes vindkraft-teknologi å utvikles betydelig i tiden som kommer. Havvind, vindturbiner til havs, er hovedsakelig bunnfaste vindturbiner, men flytende konsepter etableres for fult ... -
Eksperimentelle analyser av forankringsløsninger for Egget®.
(Master thesis, 2023-06-01)Havbruksnæringen i Norge er en voksende industri, som bidrar til å skape betydelige antall arbeidsplasser og inntekter i hele landet. Etterspørselen av oppdrettsfisk er stor både i inn- og utland, og industrien har økt i ... -
