NUMERICAL PREDICTION OF ROLL MOTION OF A SHIP WITH LIQUIDS ON BOARD IN REGULAR WAVES FROM DIFFERENT DIRECTIONS

In this paper the roll motion of a fishing vessel with free surface liquids on board is analyzed both in a regular beam sea and in a longitudinal sea. Firstly an analytical model based on the Lagrange equation representing the roll motion of the ship with free surface liquids has been developed. Successively a hydrodynamic approach involving the roll motion equation of the ship in conjunction with the Navier-Stokes equations for the determination of the sloshing loads has been used, and computations were carried out on a 1:12.5 model of a fishing vessel equipped with a rectangular tank. In addition, the effect of viscosity of the shipped liquids on the overall sloshing induced loads has been investigated in both sea conditions.
