Added Resistance of a VLCC in Short Waves
29th International Conference on Ocean, Offshore and Arctic Engineering: Volume 3, 2010In quantifying speed loss due to waves, added resistance in short waves plays an important role, because most of the time a ship travels in small sea states. It is known that added resistance in small sea states is difficult to predict accurately. In order to study improved prediction methods, numerical calculations and experiments on added resistance ...

Numerical Prediction of the Added Resistance of Ships in Waves
Volume 2: CFD and VIV, 2014The added resistance in waves is computed for different ship types using two different Reynolds-Averaged Navier-Stokes Equations (RANSE) solvers, namely Comet and interFoam (OpenFOAM). Hence, the RANS equations are implicitly coupled with the non-linear equations of motions for six degrees of freedom and the solvers are extended by algorithms for mesh ...

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

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 ...

Evaluation of Added Resistance of KVLCC2 in Short Waves
Journal of Hydrodynamics, 2011The added resistance of KVLCC2 in short and regular head waves has been studied theoretically and experimentally. Model tests are performed to determine how well the asymptotic formula (Faltinsen et al. 1980) predicts the typical level of added resistance in short waves.

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 ...

SPAWAVE, An Empirical Method to Predict Wave Added Resistance in all Wave Directions
SNAME 14th International Marine Design Conference, 2022In the last 5 years, major improvements have been made in the prediction of wave added resistance with high fidelity numerical methods like Rankine source panel methods and CFD. These methods provide accurate ship and loading condition specific predictions of added resistance in all wave conditions.

Numerical Study on Added Resistance Computations in Short Waves
Volume 7: Ocean Engineering, 2016Evaluation of added resistance in short waves is critical to the assessment of the global performance of a ship traveling in a seaway. In this paper, three methods of added resistance evaluation in short waves are briefly reviewed, including those proposed by Fujii & Takahashi [1], Faltinsen et al. [2], and Kuroda et al. [3].

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 ...

Study of Wave Added Resistance and Motions of KCS in Waves With Different Wave Lengths
Volume 7B: Ocean Engineering, 2019Abstract Estimating added resistance and motions of a ship in waves are essential to predict fuel consumption and speed loss. The added resistance and motions of the 3600 TEU KRISO container ship (KCS) in regular head waves under different wavelengths are investigated using Reynolds-Averaged Navier-Stokes (RANS) method.
