Paper presented at the SNAME Maritime Convention and 5th World Maritime Technology Conference, November 4–6, 2015
Paper Number: SNAME-WMTC-2015-009
... This paper describes numerical evaluation of radiation and diffraction forces for a ship travelling in a seaway at moderate forward speed. The method was developed with the objective of providing efficient and robust force predictions in both the frequency and time domains. For evaluation...

Paper Number: SNAME-WMTC-2015-127
... The paper presents a practical and simple approach for making vessel response predictions. Features of the procedure include a) predictions which are scaled so to better agree with corresponding true, future values to be measured at the time the predictions apply at; and b) predictions...

Paper Number: SNAME-WMTC-2015-122
..., propeller open water tests and propulsion tests, are performed. However, it is a challenge yet to analyze the uncertainty in ship performance prediction based on these model tests. In this paper, a real example of bulk carrier is presented to demonstrate implementation of the ISO GUM into uncertainty...

... and TKE budget. Results were obtained from five different solvers, which used different numerical and discretization schemes, free-surface and turbulence models and adapted grids ranging from 2.5M to 102M for =0 and 4.6M to 250M for =20 . For =0 , resistance and wave-elevation predictions compare...

... and 2nd harmonic of motions show an average error of 30%DR whereas 1st harmonic amplitude predictions show a smaller error with an average value of 12%DR over all the wave headings. For all harmonics, the largest error value was for the stern quartering wave and the smallest value was often for the head...

... simulations and RANS based on non-isotropic models proved to be superior (stronger and less dissipated vortices) than one equation isotropic models. In terms of hydrodynamic loads, a general good agreement between the submissions has been observed (standard deviation on the resistance prediction of about 3.5...

... harmonic of motions and added resistance were again large. PF studies for variable wave headings were also conducted for more wavelength condition, showing good predictions for the heave and pitch motions for all cases while the surge and roll motions and added resistance were often not well predicted...
