Bow hull-form optimization in waves of a 66,000 DWT bulk carrier
International Journal of Naval Architecture and Ocean Engineering, 2017 This paper uses optimization techniques to obtain bow hull form of a 66,000 DWT bulk carrier in calm water and in waves. Parametric modification functions of SAC and section shape of DLWL are used for hull form variation.

Numerical Investigation of Length to Beam Ratio Effects on Ship Resistance Using Ranse Method
Polish Maritime Research, 2023 The paper discusses the length to beam (L/B) ratio effects on ship resistance at three different Froude numbers using unsteady RANSE simulation. First, the JBC ship model was used as an initial hull form for verification and validation of predicted ship ...

Comparisons of Hydrodynamic Characteristics of Superyacht with Respect to the Variation of Hull Form [PDF]
Journal of the Society of Naval Architects of Korea, 2008 Abstract There are various hull types on the mid-size superyachts around 30 ~ 45m. In any case, it is important to design the proper hull shape in viewpoint of the reduction of wave resistance, because small vessels such as superyachts are running at relatively higher Froude Number than other merchant ships.

Analysis of trimaran-pentamaran side hull location based on clearance and staggers with stern form variations [PDF]
E3S Web of Conferences, 2018 An optimum design of ship is to achieve the required speed with minimum power requirements. On multihull, sidehull position against to mainhull influences the friction resistance and its stability. Frictional resistance of multi-hull increases due to the addition of wetted surface area of hull, but wave making resistance can be lowered by a slender ...
