Numerical simulation of an ice-strengthened bulk carrier in brash ice channel [PDF]
Ocean Engineering, 2020 In this paper, the CFD-DEM coupling numerical method was applied to study the ship resistance of a certain type of ice-strengthened Panama bulk carrier in the brash ice channel. The ship-water interaction is established under Euler framework, and the ship-ice interaction is realized by means of the DEM method under Lagrange framework.

International Journal of Naval Architecture and Ocean Engineering, 2023 Main engine power prediction is important for polar ships operating in brash ice channels, which is one of the most important concerns of shipowners. Self-propulsion simulation is an efficient method to predict the developed power.

Investigation of model-scale brash ice properties
Ocean Engineering, 2021 Abstract A brash ice channel is a typical operation condition for ice-going commercial vessels. The Finnish-Swedish Ice Class Rules (FSICR) define the vessels ice class performance requirements particularly in a brash ice channel. The vessel performance can be verified using model tests, which are conducted according to the FSICR guidelines. However,

Implementation of ship performance test in brash ice channel
Ocean Engineering, 2017 Abstract Vessels operating in the Baltic Sea and northern regions should satisfy the ice class rules for safe navigation; thus, shipyards should determine the most effective propulsion capacity and hull form during the design stage of a vessel. This can be done using a model test in an ice model basin and/or Finnish Swedish Ice Class Rules (FSICR ...

Brash ice macroporosity and piece size distribution in ship channels
Cold Regions Science and TechnologyMerchant vessels' performance on brash ice plays an important role in navigation in fast ice conditions in Northern Baltic ports. Among many parameters, the piece size distribution and macroporosity of the brash ice influence the accuracy of the model simulations of ship performance in brash ice.

Large-scale shear test of brash ice
Ocean Engineering, 2022 A large-scale shear apparatus has been originally developed and built to test the mechanical properties of coarsegrained material. It was used to evaluate the shear behaviour of brash ice. The brash ice blocks were collected at Luleå harbour in two separate measuring campaigns in March 2020 and March 2021.

Coupling of Finite Element Method and Peridynamics to Simulate Ship-Ice Interaction
Journal of Marine Science and Engineering, 2023 In this work, the finite element method (PD-FEM) coupling strategy is used to simulate ship-ice interaction. Two numerical benchmark tests are selected to validate the coupling approach and its program.
