ABSTRACT:
Over last few years there is a growing interest in developing the Arctic region in terms of significant hydrocarbon reservoirs, ship navigation along the Northern Sea Route and various scientific researches. One of the main hazards for arctic offshore structures and navigating ships is ice and particularly pressure ice ridges — sets of randomly oriented large pieces of sea ice. These ice ridges may affect the normal exploitation of ice-going vessels, subsea pipelines, and equipment.Nowadays still the main tool available for prediction of ice loads on ships and structures and estimation of interaction with ice is scale-model experiments in ice-tanks. On the other hand, as in other scientific branches the numerical methods and numerical simulation for ice-relates problems are continuously attempted to be introduced.Discrete Element Method (DEM) is currently considered to be a suitable tool for modelling ice-related problems, since ice blocks could undertake large independent displacements during interaction and the ice ridge itself cannot be really represented as real continuum.&nbsp;&nbsp;Modern commercial software, dealing with DEM, is usually available for soil mechanics, rock engineering and simulation of particles motion. But in order these to be applied for ice problems still there is lack of physical models for ice as material.So it can be said that there is growing demand and interest both in academic and industrial world for developing numerical simulation of ice, its various formation, and ice-structure interaction.In the final analysis developed numerical simulation helps to predict ice loads and performance of offshore structures and ships in ice conditions with less cost and time. &nbsp;&nbsp;
