Abstract

Oscillating motion of ship makes a great impact on the safety of ocean shipping of LNG tank, so a simulation system is built to study the ship oscillation under different conditions. We construct several groups of simulation environment and an algorithm based on direction spectrum to describe ocean wave spectrum according to seakeeping theory, ship oscillation simulation system based on this algorithm is built by VC++ and DirectX. The system could simulate the ship´s real-time movement under different sea conditions, and the simulation results are close to the ship´s experimental data. It could provide strong technical support to study the LNG tank ship oscillation problems.
