Except for the ice-breaking capacity in the polar regions, a Polar Research Vessel (PRV) should also have good navigation performance in open water. Three conventional ships are used for comparison to study the added resistance and vertical motions of ...

A Study on the Added Resistance Performance of Catamarans in Waves
Volume 11A: Honoring Symposium for Professor Carlos Guedes Soares on Marine Technology and Ocean Engineering, 2018The added resistance of a catamaran advancing in waves is investigated in the framework of a non-viscous potential theory. A linear Boundary Element Method (BEM) is used for the first order seakeeping prediction and the mean longitudinal component of the second-order steady-state force is computed by using a near-field method.

The Exact Calculation of the Added Resistance in Waves
Volume 12: Vibration, Acoustics and Wave Propagation, 2012The exact calculation of the added resistance in waves is a seakeeping problem of high interest due to economic effect on ship exploitation. In this paper an open uniform B-spline based method is developed to calculate added resistance. Initially this method applied to calculate velocity potential and Kochin functions that are necessary for calculation

Prediction of added resistance of ships in waves
Ocean Engineering, 2011The prediction of the added resistance of ships in waves is a demanding, quasi-second-order seakeeping problem of high practical interest. In the present paper, a well established frequency domain 3D panel method and a new hybrid time domain Rankine source-Green function method of NTUA-SDL are used to solve the basic seakeeping problem and to calculate

Energy analysis of ship motion in waves and a novel method for predicting wave added resistance
The Physics of FluidsEnergy analysis of ship motion in waves is carried out, and a novel method to predict the corresponding wave added resistance is proposed in this paper. First, a semi-analytical three-dimensional translating and pulsating source method that accounts for ...

Added Resistance of Ships in Waves
Journal of Hydronautics, 1978A new method is presented for computing the added resistance of a ship advancing at constant mean speed and heading in regular waves. It is shown that the added resistance, even though it is a second-order quantity, can be expressed as a product of first-order terms that are all computed by computer programs presently in use for predicting the linear ...

A Rankine Panel Method for Added Resistance of Ships in Waves
Journal of Offshore Mechanics and Arctic Engineering, 2012A new Rankine panel method and an extended Reynolds-Averaged Navier–Stokes (RANS) solver were employed to predict added resistance in head waves at different Froude numbers of a Wigley hull, a large tanker, and a modern containership. The frequency domain panel method, using Rankine sources as basic flow potentials, accounts for the interaction of the ...

Numerical and Experimental Analysis of Added Resistance of Ships in Waves
Volume 11: Prof. Robert F. Beck Honoring Symposium on Marine Hydrodynamics, 2015A RANS-based field method numerically predicted added resistance in regular head waves for a 14000 TEU containership (Duisburg Test Case) and a medium-size cruise ship. We concentrated our investigations on short waves. For different frequencies, we decomposed added resistance into diffraction and radiation force components, whereby diffraction forces ...

Numerical and Experimental Analysis of Added Resistance of Ships in Waves
Journal of Offshore Mechanics and Arctic Engineering, 2016Two Reynolds-Averaged Navier–Stokes (RANS) based field methods numerically predicted added resistance in regular head waves for a 14,000 TEU containership and a medium size cruise ship. Long and short waves of different frequencies were considered. Added resistance was decomposed into diffraction and radiation force components, whereby diffraction ...
