Resistance of a Compartmented Surface-Effect Ship [PDF]
Journal of Ship Production and Design, 2010 A series of carefully controlled experiments on the resistance of a model of a compartmented surface-effect ship has been conducted in a towing tank. Configurations of the model included cases encompassing one subcushion and two subcushions, as well as differing values of the pressures in the subcushions. It was shown that a reduced total resistance in

Ship resistance performances assessment for a containership
Annals of "Dunărea de Jos" University of Galaţi: Fascicle XI Shipbuilding, 2021 The present work is focused on ship resistance performances assessment for a given capacity containership. Starting from the main dimensions of a parent ship, other ten hull forms have been generated using DELFTship free program.

PENGGUNAAN METODE KOMPUTERISASI DALAM PENENTUAN TAHANAN KAPAL TANKER
Rotor: Jurnal Ilmiah Teknik Mesin, 2017 The ship resistance is influential to choose the ship's main engine, especially tankers that have large block coefficients. In general, ship resistance was obtained by modeling the vessel on a certain scale and then testing on the experimental tank ...
