Interaction between bodies in a viscous flow
(Master thesis, 2011)Using the open-source CFD-solver OpenFOAM with a numerical scheme which is first order in time and second order in space, calculations of unsteady 3D flow around two cylinders in tandem arrangement at low Reynolds number ... -
Interactive hyperspectral data inspection during field operations
(Peer reviewed; Journal article, 2022)Hyperspectral data cubes generated from hyperspectral cameras can be hard to inspect in during a field operation as the data is collected. This is due to the high spectral dimension of the data, resulting in large data ... -
Internal cutting of offshore wind turbine monopiles
(Master thesis, 2024)Havvind regnes som en av de mest lovende løsningene for å dekke samfunnets økende energibehov på en bærekraftig måte. Derfor er det store byggeprosjekter og massive utbyggingsplaner for nye havvindparker over hele verden. ... -
Interrelationships of LNG cargo containment systems and machinery configurations on LNG carrier - design and operational factors with economic assessment
(Master thesis, 2012)The main objective of this project has been to design a ship for LNG trade between Port Moresby and Singapore, with a cargo capacity corresponding to a total freight work in the range of 1.000,000 - 800,000m3 annually. The ... -
Inventory Managemement, Scheduling and Routing in Fish Feed Distribution
(Master thesis, 2019)Denne masteroppgaven tar for seg ruting av skip, brukt til å betjene et industrielt nettverk av noder som dekker lokasjoner for lakseoppdrett langs norskekysten. Oppdrettslokasjonene betjenes med fôr som produseres ved ... -
Investigating a Simplified Model for Moonpool Piston Mode Response in Irregular Waves
(Chapter, 2018)Estimating moonpool piston mode response at resonance is important for operation safety. This is a difficult task, in particular, due to nonlinear nature of the moonpool response connected to the damping imposed by the ... -
Investigating feasibility of flexible ship concepts using tradespace network formulations
(Chapter, 2016)In this paper, we investigate the technical feasibility of flexible offshore ship design concepts with respect to retrofits. Flexibility is intended to improve performance, but there are often complex system interactions ... -
Investigating Operational Patterns for Three Different Modes of Operation in Shipping Using AIS Data
(Master thesis, 2019)Denne masteravhandlingen bruker data fra Automatic Identification System (AIS) til å analysere operasjonsmønstre for ulike måter å operere i shipping. Effektiv drift av skip har aldri vært mer aktuelt, og er viktig sett ... -
Investigating Statistical Modelling of Excitation Forces in Inhomogeneous Waves
(Chapter, 2024)In coastal areas, and especially fjords, the wave field can present inhomogeneities that affect the responses of floating bridges among other very large floating structures. Recent studies have begun to include the effects ... -
Investigating tradeoffs between performance, cost and flexibility for reconfigurable offshore ships
(Journal article, 2018)This paper investigates tradeoffs between technical performance, cost and flexibility level for reconfigurable offshore ships. An offshore ship can be configured with various types of equipment; thus, its base structure ... -
