A Comparative Study of the Energy Efficiency of Hydrofoil Vessels and Slender Catamarans
Godø, John Martin Kleven; Steen, Sverre (Chapter, 2023)The transition to zero-emission energy systems introduces new challenges in fast ferry design, particularly in relation to the increased weight and cost associated with stored and consumed energy. Hydrofoils may address ... -
An Efficient Method for Design and Powering Prediction of Fast Slender Catamarans
Godø, John Martin Kleven; Steen, Sverre; Faltinsen, Odd Magnus (Journal article; Peer reviewed, 2023)This paper presents a parameterized and mathematically defined hull shape that can be tuned to represent modern passenger fast ferries. Additionally, a resistance calculation model for high-speed slender round-bilge ... -
An Efficient Method for Unsteady Hydrofoil Simulations, based on Non-Linear Dynamic Lifting Line theory
Godø, John Martin Kleven; Steen, Sverre (Journal article; Peer reviewed, 2023)This paper presents a Non-linear Dynamic Lifting Line (NDLL)-based method for analysing hydrofoil vessels in waves. The method is validated, and its utility is demonstrated in a case study. The NDLL accounts for dynamic ... -
Optimal Energy Management for Zero-Emission High-Speed Passenger Vessels
Najjaran, Samieh; Skjetne, Roger; Godø, John Martin Kleven (Chapter, 2023)To comply with IMO’s regulations on reduced emissions, the maritime industry is investigating various alternatives to achieve zero-emission high-speed passenger vessels (HSPVs). In this work, optimal loadsharing is studied ... -
Zero-Emission Hydrofoil Fast Ferries: Design, Modelling, and Performance Evaluation
Godø, John Martin Kleven (Doctoral theses at NTNU;2024:496, Doctoral thesis, 2024)Hydrofoil technology can potentially reduce the resistance and energy requirement of high-speed ferries, thus lowering fuel consumption and emissions or extending the range of zero-emission vessels. Although substantial ...
