Abstract
With the growth of global warming, the scope and the thickness of sea ice decrease drastically. In order to monitor this trend, polar geophysical vessels travel to the polar region frequently. The resistance of the geophysical exploration ships in polar areas will increase due to the change of the environments, and the towing operation of those ships will also be affected. Thus, it is of great significance to carry out ice load analysis and parameter sensitivity research on the geophysical exploration ship in ice floe environments. In the present paper, the numerical curve of the ice load over time has been obtained via FEM simulation. The influence of sensitivity parameters (speeds and ice sizes) on the towing cables has been analyzed. On the basis of the calculation results, an empirical formula suitable for the collision between towing cables and ice has been summarized and verified.
