Abstract
In this paper, with the help of MATLAB and Auto CAD, some curves are drawn based on the observed data of the Jinzhou20-2MUQ platform. The regression analysis is applied to analyze the momentum equation of sea ice drifting and numerical simulation is employed to analyze the track of sea ice drifting. This paper focuses on the relationships of sea ice motion, ocean currents and sea surface wind elements, and the results that the directions of sea ice motion and ocean currents are apparently consistent and that the velocities of the sea ice and the surface current are correlative with each other are obtained, although there are still some differences between them which can't be neglected. And after studying about the observed data, we also discover that the wind velocity and direction also have some degrees of influence on the sea ice motion. Based on the law of sea ice motion, this paper has expounded the influence of sea ice on the platform structure and the sea ice disaster which might happen. The ASARP theory is employed to study and manage the sea ice disaster, which has significant meanings to the early-warning and evaluation of sea ice disaster.
