Open publisher page 2 citations

Abstract

Ship navigation performance more and more attention in real sea conditions.To study the properties of ship motion in waves, Applling hydrodynamics calculation software for AQWA-line and AQWA-AGS modules and taking into account the role of random wave load, 2450DWT a small oil tanker in simulation and analysis of a campaign response under sea conditions, Calculate shipping in several waves under the angle of vertical and horizontal swing, heave, pitch, roll and the first rolling response amplitude operators of RAOs, additional parameters such as quality and radiation damping. Application of spectrum analysis method, ITTC wave with two parameters, which strike the spectral density of ship motion, and finally using Excel to calculate sprawling forecast prediction of ship under irregular wave.
