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 ... -
Investigation into the Capabilities of Linear Theory for Numerical Modelling of Wave-Body Interactions for a 2D Heaving Buoy - Application to Wave Energy Converters
(Master thesis, 2017)Numerical modelling of wave energy converters (WECs) is currently an area of interest within the marine renewable energy industry, due to its ability to streamline design processes and accelerate scientific understanding. ... -
Investigation of an air-cushion supported solar island
(Chapter, 2018)A preliminary investigation of a low-weight carrying marine platform concept was conducted by means of experiments and approximate theories. The platform consists of a circular elastic tube with circular cross-section, ... -
Investigation of Combined Heating and Cooling Systems with Short-and Long-Term Storages
(Peer reviewed; Journal article, 2022)Modern buildings in cold climates, like Norway, may have simultaneous heating and cooling demands. For these buildings, integrated heating and cooling systems with heat pumps, as well as short-term and long-term thermal ... -
Investigation of drivetrain losses of a DP vessel
(Chapter; Peer reviewed, 2017)Traditionally the efficiency of the drivetrain of a marine vessel is evaluated at rated power and speed. However, the thrust and power consumption of the thrusters are low during DP operation. In this study, the loss energy ... -
investigation of hybrid power plant configurations for an offshore vessel with co-simulation approach
(Peer reviewed; Journal article, 2023)This work presents a full-system simulator consisting of a generic power system integrated with a vessel model and real-time capabilities. The whole system simulation facilitates evaluating the overall system performance ... -
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 ... -
