Reliability and Maintenance Analysis of Marine Hybrid Power and Propulsion Systems
Wang, Ziwen (Master thesis, 2023)This thesis aims to provide a reliability and maintenance analysis of marine hybrid power systems and figure out the effect of vessel operation contexts and system redundancies. The Multi-phase Markov method is implemented ... -
A Robust Circuit and Controller ParametersIdentification Method of Grid-Connected VoltageSource Converters Using Vector Fitting Algorithm
Zhou, Weihua; Torres Olguin, Raymundo E.; Göthner, Fredrik T. B. W.; Beerten, Jef; Zadeh, Mehdi; Wang, Yanbo; Chen, Zhe (Peer reviewed; Journal article, 2021)This article presents a vector fitting (VF) algorithmbased robust circuit and controller parameters identification method for grid-connected voltage source converters (VSCs). The dq-domain impedance frequency responses ... -
Shipboard DC Hybrid Power Systems: Pathway to Electrification and Decarbonization
Zadeh, Mehdi; Ghimire, Pramod (Chapter, 2023)Ship power and propulsion systems are being electrified for several reasons out of which emission reduction, energy efficiency improvement, and ultimately reduction in operating expense (OPEX) are the main drives. ... -
Shore Charging for Plug-In Battery-Powered Ships: Power System Architecture, infrastructure, and Control
Karimi, Siamak; Zadeh, Mehdi; Suul, Jon Are Wold (Peer reviewed; Journal article, 2020)This article reviews the available systems for shore-to-ship high-power charging, including recent technologies, control methods, and related challenges. The battery charging path from shore to the onboard battery involves ... -

Simulation Based Estimation of Power Consumption
Thorsen, Siri Helene Ludviksen (Master thesis, 2019)De siste årene har den maritime industrien fått en betydelig interesse for å redusere drivhusgass utslippene fra næringen. Strenge krav som har trådt i kraft har ført til at skipsbyggere har blitt tvunget til å handle raskt ... -
Simulation-Based Ship Hybrid Power System Concept Studies and Performance Analyses
Ghimire, Pramod (Doctoral theses at NTNU;2022:166, Doctoral thesis, 2022)The stricter regulations for emissions reduction and energy efficiency improvement are driving the maritime industries towards implementing greener and more energy-efficient solutions, one of which is a battery-based hybrid ... -
Sizing Optimization of a Hybrid Shipboard Power System for Low-Emission Shipping
Michaelsen, Tor Magnus Clemens Kvinnsland (Master thesis, 2019)Valget av maskinerisystemet for et skip er i utgangspunktet en kompleks oppgave. Skip er konstruert med tanke på en levetid på 20-25 år, og vil derfor være utsatt for både endringer i operasjonelle krav, så vel som ... -
Sustainable Power System Design for Green Shipping - a case study of a cruise ferry
Gallefoss, Andreas Størdal (Master thesis, 2021)En bærekraftig utvikling for fremtiden har aldri vært mer relevant ettersom det globale miljøavtrykk fortsetter å vokse. En reduksjon av utslippene som truer det globale livet slik vi kjenner det i dag, er viktig for å ... -
Techno-economic modeling of zero-emission marine transport with hydrogen fuel and superconducting propulsion system: Case study of a passenger ferry
Mojarrad, Masih; Zadeh, Mehdi; Rødseth, Kenneth Løvold (Peer reviewed; Journal article, 2023)This paper proposes a techno-economic model for a high-speed hydrogen ferry. The model can describe the system properties i.e. energy demand, weight, and daily operating expenses of the ferry. A novel aspect is the ...
