(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 ... -
Investigation of the Effects of Mass Flow Meters on the Singaporean Bunker Industry
(Master thesis, 2019)Denne oppgaven undersøker om massestrømmålere har en effekt på bunkersindustrien i Singapore. Drivstoffkvalitetsdata og prisdata blir analysert for å finne endringer som følge av eventuelle effekter av massestrømmålere. ... -
Investigation of the Tower Design for the Offshore Wind Turbine Concept OO-Star Wind Floater

Investigation of the Wake Flow behind a stepped circular Cylinder using Particle Image Velocimetry
(Master thesis, 2012)Subject of the present study was the investigation of the wake behind stepped circular cylinders. Experiments were performed using particle image velocimetry (PIV). Cylinder models with diameter ratios D/d=1, D/d=6/5 and ... -
Investigation of thrust loss due to steering while trawling
(Master thesis, 2017)This thesis investigates the potential for a reduction in required propeller power by optimizing the transverse position of attachment points for trawl warps, simulating a system of movable trawl blocks. Full scale ... -
Investigation of wave-induced nonlinear load effects in open ships considering hull girder vibrations in bending and torsion
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:357, Doctoral thesis, 2012)For ships with open cross sections, such as container vessels, it is of primary importance to accurately estimate torsional moment (TM) and horizontal bending moment (HBM) as well as vertical load effects. In recent decades, ... -
Investigation of Wave-Induced ULS and ALS Characteristic Loads and Responses on a Pile Structure in the Ekofisk Area - Importance of Breaking Waves
(Master thesis, 2016)A set of metocean contour lines corresponding to annual exceedance probabilities of 10^(-2) and 10^(-4) describing the environmental conditions at the Ekofisk area are established based on hindcast data. These are divided ... -
investigation of which sea states yield the dominating contribution to fatigue accumulation in offshore structure
(Master thesis, 2015)In assessment of the fatigue damage, it has been assumed that the moderate sea states (significant wave height ranged between 4-8m) should have major influence on the offshore structures because they have relatively more ... -
