A numerical model for real-time simulation of ship–ice interaction

Cold Regions Science and Technology, 2011
Abstract A ship advancing in level ice will introduce several failure processes to the ice sheet, such as localised crushing and breaking due to bending stresses. The resulting ice fragments will interact with each other, with water and with the hull of the ship.

Simulation of Ship-Ice Interaction in Level Ice

Volume 7: Polar and Arctic Sciences and Technology, 2020
Abstract This paper presents the capabilities of a ship-ice interaction simulator developed at the Hamburg University of Technology for the ship operation in level ice. Besides a brief introduction of the fundamentals of the simulator and the full availability of the source code, the capabilities of the simulator in terms of the ...

Numerical Simulation of Ship-Ice Interaction

Volume 8: Polar and Arctic Sciences and Technology; Petroleum Technology, 2019
Abstract The increasing activities in arctic sea areas over the last years have led to a rising demand for numerical tools to design and evaluate ice-going ships. Numerical simulation of ship-ice interaction can be a suitable method for engineers to evaluate ship designs in early development phases.

Finite element analysis of ship/ice interaction

Computers & Structures, 1992
Summary: The transient nonlinear dynamic response of an intermediately thick floating ice-field to ship impact forces has been determined. The finite element method has been utilized in the numerical analysis of the problem, using eight-noded plate elements. Step-by-step integration of the equations of motion has been carried out.

The Influence of Added Mass in Ship-Ice-Wave Interactions: A Potential Flow Hydromechanics Model

Volume 2: Structures, Safety, and Reliability, 2022
Abstract For ships navigating in ice floe fields, ship-ice-wave interactions may have significant influence on ship performance and ice impact forces. This is because added mass may affect the hydrodynamic interaction between a ship with ice floes. This paper explores the influence of added mass using a Boundary Element Method (BEM). The

Numerical Prediction of Ship-Ice Interaction: A Project Presentation

Volume 8: Polar and Arctic Sciences and Technology; Petroleum Technology, 2017
It is inevitable that commercial shipping and oil and gas resource exploitation activities in the Arctic will increase due to decreasing sea ice extent caused by global climate changes. Significantly more demanding and at the same time less well known environmental conditions create a need for reliable methods to assess icebreaking performance ...

Physical modelling of ship/ice interaction

1991
The report describes the second and final phase of a joint research project between Canada and Finland. The objective of the work was to experimentally investigate the mechanics of a ship ramming a massive ice floe. In the first phase, models of the vessel M.V. Arctic were tested and compared with full scale data.

Ship/Ice Interaction Pressures and Energies During Ship Ramming

Journal of Offshore Mechanics and Arctic Engineering, 1989
Abstract This paper shows that ice interaction forces and energies can be related to the characteristics of ice such as strength, stiffness and rheological properties on the one hand, and to the parameters of the impact such as impact velocity, confinement and size of the contact area on the other hand.

Local contact pressures in ship/ice and structure/ice interactions

Cold Regions Science and Technology, 1993
Abstract Data on local ice pressures and forces were compiled. The two primary sources were controlled indenter experiments in the field and ship trials. Loads and average local pressures on areas up to 7 m2 were examined. All the data were plotted on a basis of average pressure versus contact area.
