Analytical surfaces for ship hulls

open access: yesRUDN Journal of Engineering Research, 2021
The choice of optimal shape of ship hull surface is one of the main problems of ship architects and designs. A choice of the form is based on empirical formulae or on intuition of designers.

An artificial intelligence-aided design (AIAD) of ship hull structures

open access: yesJournal of Ocean Engineering and Science, 2023
Ship-hull design is a complex process because the any slight local alteration in ship hull structure may significantly change the hydrostatic and hydrodynamic performances of a ship. To find the optimum hull shape under the design requirements, the state-

Research on the hull form optimization using the surrogate models

open access: yesEngineering Applications of Computational Fluid Mechanics, 2021
The ship hull form optimization using the Computational Fluid Dynamics (CFD) method is increasingly employed in the early design of a ship, as an optimal ship hull form can obtain good hydrodynamics.

Hydrodynamic surfaces with midsection in the form of Lame curve

open access: yesRUDN Journal of Engineering Research, 2021
General representation of ship geometry is given by the method of slicing the ship hull by three mutually perpendicular planes: vertical symmetry plane which runs along the middle of hull width, horizontal plane which divides the hull into underwater and

Analysis of the Effect of Hull Vane Lifting Force on Fast Vessel Resistance: Straight Hull Vane

open access: yesWave, 2023
In previous studies by Saputra, the use of straight Hull Vane® increased ship's resistance. Based on hypothesis, this was caused by lifting force from Hull Vane® being too large, so that ship experienced bow trim.
