Abstract
The article focuses on CFD (Computational fluid dynamics) application with Fluent-Ansys to calculate and simulate the impact force on the ship at full load and ballast conditions when anchoring in the Vung Tau in the case of changing arround flow speed. For each ship, the anchorage area characteristics, and hydrometeorological factors are known. On this basis, the article applicated CFD to calculate and simulate the impact force on a hull of a ship for the known object is M/T AU LAC JUPITER which has 13.654 DWT, according to Froude standard, coefficient k=100, in the case of full load and ballast conditions.
