Investigation of Hydrodynamic Aspects of the Design of the Universal Buoyancy Concept (UBC) Loading Buoy
(Master thesis, 2012)A new loading and discharge concept for ships, referred to as the Universal Buoyancy Concept (UBC), is proposed as an effective alternative to land based infrastructure for distribution of primarily LNG. The UBC system ... -
Investigation of Hydrodynamic Performance of a Twin-Screw Trawler Using CFD
(Master thesis, 2015)Previously experimental methods or empirical knowledge laid the foundation for ship design. Performing a model test in a towing tank is time consuming and expensive. In addition to this, studying detailed effects in a ... -
Investigation of Incentives for the Introduction of Low Carbon Fuels for Vessels Operating in the Arctic
(Master thesis, 2019)De siste årene har det vært stadig større fokus på marin aktivitet i nord-områdene og hvordan dette påvirker, og vil påvirke miljøet både lokalt og globalt. Isen har på kort tid trukket seg drastisk tilbake, og fjordene ... -
Investigation of inhomogeneous wave conditions in Sulafjorden
(Chapter, 2021)Complex fjord topography (bathymetry and coastline) may differentiate significantly wave conditions not only compared with the offshore ones but in the vicinity of few tens of meters. In the present work, possible ... -
Investigation of Moonpool Resonance as Vessel Damping Device
(Master thesis, 2016)The starting point of this thesis is to introduce the potential and the viscous flow formulations of a two-dimensional moonpool geometry, and the viscous approach demonstrates compliance with physical experiments. The ... -
Investigation of moonpools as pitch motion reducing device
(Peer reviewed; Journal article, 2021)Moonpools as a device for reducing pitch motion is investigated experimentally, numerically and by an approximate theory. A two-dimensional study is carried out of a rectangular body with two moonpools. Forced heave and ... -
Investigation of Multivariate Freight Rate Prediction Using Machine Learning and AIS Data
(Master thesis, 2018)This thesis investigates whether multivariate machine learning forecasting methods, using information extracted from Automatic Identification System (AIS) data, add additional information in predicting short-term freight ... -
Investigation of Parametric Resonance in Roll for Container Carrier Ships
(Chapter; Peer reviewed, 2015)Parametric roll resonance is of concern for container and fishing vessels, especially in head-sea waves. Here this phenomenon is investigated with a numerical method based on potential-flow theory with viscous corrections ... -
INVESTIGATION OF PERFORMANCE OF HIGH LIFT RUDDERS IN COMPARISON WITH STANDARD MANOEUVRING EQUIPMENT
(Master thesis, 2020)Abstract will be available on 2025-09-01 -
Investigation of Roll Damping on an FPSO with Sponsons and Bilge Keels
(Master thesis, 2017)Within Hydrodynamics, estimating the roll damping are associated with difficulties and uncertainty. This is due to roll motion being highly non-linear compared to other degrees of freedom. The non-linearity arises from ... -
Investigation of Sloshing Inside Closed Aquaculture Plants
(Master thesis, 2017)This thesis concerns the sloshing effect inside closed fish farm plants exposed to external waves. To investigate the sloshing phenomenon, linear potential theory together with linear modal theory was implemented, and a ... -
Investigation of the Effect of Propeller Location with the use of CFD
(Master thesis, 2019)Målet med denne masteroppgaven var å analysere propellens ytelse ved forskjellige plasseringer i lengderetning ved hjelp av numeriske metoder. Motivasjonen for studien er hovedsakelige å redusere drivstofforbruket og ... -
Investigation of the effect of sloshing in a floating closed fish farm
(Master thesis, 2018)In this thesis, the effect of sloshing on the dynamic response of a floating closed containment system(FCCS) has been investigated. Results from the SINTEF OCEANS experiment SJØFLO have been examined and compared to numerical ... -
