URANS Calculation of Ship Heave and Pitch Motions in Marine Simulator Based on Overset Mesh
So as to improve the reliability and accuracy of marine simulators, it is essential to predict ship heave and pitch motions in regular waves. The motions of two ships, the international standard model KVLCC2 and the first training ship, “Yukun”, of ...

Increase of the Ship Fuel Consumption Due to Added Resistance in Waves [PDF]
Added resistance in waves is the second-order steady force dependant on the ship motions. It significantly affects ship operability and cause speed loss. Therefore the required power and fuel consumption of a ship advancing in a seaway are increasing. In

Evaluation of the added resistance and ship motions coupled with sloshing using potential flow theory [PDF]
Ship added resistance is a steady force of the second order which depends on the ship motions and wave diffraction in short waves. To predict the impact of liquid motions inside the ship hull, a flooded tank in the midship area is generated and the ship ...

CFD investigation into seakeeping performance of a training ship [PDF]
The numerous ship accidents at sea have usually resulted in tremendous loss and casualties. To prevent such disastrous accidents, a comprehensive investigation into reliable prediction of seakeeping performance of a ship is necessarily required.

A deep learning method for the prediction of 6-DoF ship motions in real conditions
This paper presents a deep learning method for the prediction of ship motions in 6 Degrees of Freedom (DoF). Big data streams of Automatic Identification System (AIS), now-cast, and bathymetry records are used to extract motion trajectories and idealise ...
