... ABSTRACT The continuous melting of Arctic sea ice has attracted increasing interest in the potential of navigation in the Arctic route. Most existing studies use the sea ice concentration (SIC) to evaluate the sea ice condition along the route. Based on the historical sea ice data (including...

..., the failure behavior of the level ice and the characteristics of the ice loading on the structures were investigated. Finally, the test data were applied to verify a self-developed numerical simulation model based on the cohesive element model and the degraded constitutive model of sea ice, the simulation...

... in sea ice are also interested and lacking study. To this end, we proposed a risk assessment model based on the artificial potential field theory, including two parts: a) the icebreaker risk field and b) the sea ice risk field. The icebreaker risk field describes the ship-to-ship collision risk, while...

... ABSTRACT In this paper, a numerical calculation method of coupling CFD (Computational Fluid Dynamics) and DEM (discrete element method) is proposed. Some technical issues are discussed, including the establishment of numerical ice pools, calibration of the parameters of the sea ice discrete...

... ABSTRACT Ice bending fracturing is a major failure mode for sea ice act on offshore wind turbines (OWTs) with icebreaker. The cohesive element method (CEM) is applied to simulate the bending fracturing and fragmentation accumulation of the level ice in the presented study. The elastoplastic...

... Abstract The relationship between the solar activity and Antarctic sea ice extent (SIE) has been intensified during recent years (2005-2019) and the observed sharp decrease in Antarctic SIE since 2014 may be partly attributed to the decline of recent solar cycle. Diagnosis analysis reveals...

... Abstract Due to the interaction with land or other (larger) ice masses, high internal stress can occur inside sea ice. During the MOSAiC Expedition the level ice pressure in the vicinity of the research vessel Polarstern was measured over a time period of six months by three pressure panels...

.... And the flexural strength calculation formula was derived. Then, different parameters were employed for the numerical simulation of ship-level ice interaction to simulate the collision between a ship and sea ice with different strengths. The method proposed in this paper can be used to study the influence of sea...

... ABSTRACT The soft yoke mooring system is considered to be one of the best mooring methods for Floating Production Storage and Offloading (FPSO) on shallow seas, which is widely used in the Bohai Sea, China. Ice load is the main environmental load in this area. The effect of sea ice on single...
