Abstract
Nowadays, there are many studies conducted in the field of marine hydrodynamics which focus on two vessels traveling and floating in sufficiently close proximity to experience significant interactions. The hydrodynamic behavior of parallel moving ships in waves is an interesting and important topic of late. A numerical investigation has been carried out for the prediction of wave exciting forces and motion responses of parallel moving ships in regular waves. The numerical solution was based on 3D distribution technique and using the linear wave theory to determine the exciting forces and ship’s motion. The speed effects have been considered in the Green function for more realistic results. The numerical computations of wave exciting forces and motion responses were carried out for a Mariner and Series 60 for the purpose of discovering different Froude numbers and different separation distances in head sea conditions. Based on the numerical computations, it was revealed that the sway, roll and yaw have a significant effect due to hydrodynamic interaction.
