Hybrid observer for improved transient performance of a marine vessel in dynamic positioning
(Journal article; Peer reviewed, 2016)Dynamic positioning (DP) systems are used on marine vessels for automatic station keeping and tracking operations solely by use of thrusters. Observers are key components of DP systems, and two main types are proposed in ... -
Hybrid Observers for Autonomous Surface Vessels Experiencing Varying Operational Conditions
(Master thesis, 2021)Denne masteroppgaven tar for seg bruk av hybrid kontrollteori for å forbedre observer-ytelse i transienter på grunn av varierende operasjonelle forhold for marine overflatefartøy. Oppgaven begynner med litteraturstudie ... -
Hybrid power plant concepts for marine vessels
(Master thesis, 2017)As the requirements of energy supply for ships and marine vessels are becoming more rigorous and complex, new power supply methods are in highly interests in recent years. Flywheels used for energy storage have been used ... -
A Hybrid Power System Laboratory: Testing Electric and Hybrid Propulsion
(Peer reviewed; Journal article, 2019)Onboard hybrid power systems with low -emission energy carriers are a promising solution for green shipping replacing conventional diesel engine -based energy systems. However, there are several existing challenges related ... -
Hybrid testing of deep water moored structures
(Master thesis, 2014)This thesis presents a design concept for deep water model testing of moored floating offshore structures in ocean basin, and presents a single degree of freedom (SDOF) test setup for this purpose. Conventional methods has ... -
Hybrid Testing of Deep Water Moored Structures
(Master thesis, 2010)This masters thesis presents a possible solution for deepwater model testing of floating production units (FPU) in ocean basins, and investigates some aspects of the method. At present, the existing ocean basins have a ... -
Hybrid Tracking Controller for an ASV Providing Mission Support for an AUV
(Peer reviewed; Journal article, 2022)Autonomous underwater vehicles (AUVs) rely on surface support for communication with operators and position fixes to bound inertial navigation errors. By installing an acoustic modem on an autonomous surface vehicle (ASV), ... -
Hybridization of General Cargo Ships to meet the Required Energy Efficiency Design Index
(Master thesis, 2015)In this thesis a hybrid propulsion system is proposed for a general cargo ship with the aim to meet the required Energy Efficiency Design Index (EEDI). The study has investigated how a hybrid propulsion system will influence ... -
Hydro-Elastic Analysis of a Floating Bridge in Waves Considering the Effect of the Hydrodynamic Coupling and the Shore Sides
(Chapter, 2018)A new numerical method, which is based on three-dimensional (3D) potential flow theory and finite element method (FEM), is used to predict the wave-induced hydroelastic responses of flexible floating bridges. The floating ... -
Hydro-plastic response of beams and stiffened panels subjected to extreme water slamming at small impact angles, Part I: An analytical solution
(Journal article; Peer reviewed, 2019)Water impact (slamming) is a strongly nonlinear phenomenon including significant fluid structure interactions. In the case of slamming with a small impact angle between the structure and water, the coupling between ... -
Hydro-plastic response of beams and stiffened panels subjected to extreme water slamming at small impact angles, Part II: Numerical verification and analysis
(Journal article; Peer reviewed, 2019)An analytical model has been proposed for the response of beams and stiffened panels subjected to extreme flat or nearly flat water impacts in Part I of the two-part companion paper. The model aims to capture the significant ... -
Hydro-plastic slamming
(Chapter, 2019)Ships and offshore structures will unavoidably experience water impacts (slamming) through-out their service time. During slamming, the coupling between hydrodynamic pressure and the elastic structural response, termed as ... -
Hydroacoustically Aided Inertial Navigation for Joint Position and Attitude Estimation in Absence of Magnetic Field Measurements
(Journal article; Peer reviewed, 2017)When an underwater intervention vehicle is close to large metallic structures, e.g. subsea oil and gas facilities, magnetic disturbances might render magnetic field measurements biased or useless. This loss of information ... -
