STOCHASTIC DEM ICE MODELS PERSPECTIVE

Abstract

The Discrete Element Method (DEM) serves as a crucial computational tool in studying ice-structure interactions pertinent to offshore marine constructions. The article highlights the significance of DEM in simulating and comprehending the complex dynamics of ice loads on offshore structures. Offshore marine constructions face challenges associated with ice loads, especially in regions prone to icy conditions. DEM, adapted to model ice behavior, offers a micro-scale perspective, representing individual ice particles to capture their interactions with offshore structures. This approach enables the assessment of ice-induced forces, structural responses, and failure mechanisms critical for designing resilient offshore installations. We underscore DEM's role in simulating ice-structure interactions, encompassing phenomena such as ice crushing, fracturing, and the dynamic response of offshore structures subjected to varying ice loads. These simulations aid in evaluating the structural integrity and performance of offshore installations, contributing to the design and optimization of platforms, rigs, and offshore wind structures in ice-prone environments. Challenges in DEM modeling for ice calculations for offshore marine constructions include the accurate representation of ice properties, validation against experimental data, and computational demands for simulating large-scale systems. However, ongoing advancements in computational capabilities, refinements in ice modeling techniques, and integration with experimental observations continue to enhance the accuracy and reliability of DEM simulations for offshore structures in icy environments.
