A method for estimation of equivalent-volume ice thickness based on WMO egg code in absence of ridging parameters
Milakovic, Aleksandar-Sasa; Schütz, Peter; Piehl, Henry Peter; Ehlers, Sören (Journal article; Peer reviewed, 2018)When calculating equivalent-volume ice thickness along a vessel's projected route for the purpose of ice resistance estimation, information on both undeformed ice (level ice) and deformed ice (mainly ridges) is needed. ... -
Design Optimization of Exhaust Gas Economizer Using CFD Simulations for Medium Speed Marine Diesel Engines Combine with Exhaust After Treatment
Hewagama, Prabath Priyadarshana (Master thesis, 2021)Denne oppgaven presenterer optimaliseringen av avgassøkonomiseringsenheten til et spillgjenvinningssystem for en middels hastighets marine dieselmotor ved bruk av CFD-simuleringer og kombinert systemkonseptutvikling med ... -
Digital Twin for Structural Monitoring and Predictive Maintenance of a Maritime Crane
Villarreal Lozano, Carolina (Master thesis, 2020)Industry 4.0 has revolutionized the industries by the application of technology in multiple ways. One of its focus is digital twins, which are virtual representations of physical products simulated in specialized software ... -
Experimental Strength Analysis and Material Modelling of 3D Printed Parts
Thorsen, Anders Dahle (Master thesis, 2019)Ingeniørens omfattende kunnskaper om styrkeanalyser er i all hovedsak basert på tradis- jonell analysemetodikk fra langt tilbake i tid. Nå som verden beveger seg fremover, popper det stadig opp nye teknologier, produkter, ... -
Hydrodynamic Investigation of Central Hauling Pools for Longline Vessels
Sæther, Sivert Olsvik (Master thesis, 2019)Dragerbrønnen har nå blitt en industristandard for linefartøy, men der har ikke vert mye forsking og utvikling på dragerbrønnen siden det første fartøyet ble sjøsatt i 1998. Skipsredere og designere har nå funnet rom for ... -
Multilayer Spooling of High Performance Synthetic Fibre Ropes. Experimental investigations of rope properties and stresses in winch drums
Skarbøvik, Reidar André (Doctoral theses at NTNU;2021:337, Doctoral thesis, 2021)Winch drums can appear as relatively simple mechanical components. However, accurate quantification of loads in multilayer winch-rope systems depends on a complex interaction between rope and drum. As vital parts of ... -
Numerical Analysis and Model Tests of Hydrodynamic Loads on Perforated Plates
Sihan, Gao (Master thesis, 2020)Perforated plate structures are widely applied in the maritime industry, while the hydrodynamic loads on them are hard to predict. This thesis aims to explore a methodology to utilize Computational Fluid Dynamics (CFD) in ... -
Performance Prediction and Design Modification of a Ship in Waves Using Computational Fluid Dynamics
Eiksund, Oline (Master thesis, 2020)Skipsdesignsindustrien utvikler seg hele tiden, og fokuset rundt ytelse og effektivitet blir stadig viktigere. Hvordan skipet responderer til eksterne krefter påvirker komfortnivået ombord, og spesielt i tøff sjø kan det ... -
