Abstract

Brash ice channels are frequently created during ship navigation. To improve the understanding of the brash ice channel development experimental tests have been conducted. The tests were performed by repeated passage of a model ship in a ship channel. Channel profile measurements, temperature profiles, salinity of cores were taken from consolidated brash ice edges and centre of the channel, as well as measurements of the ship model parameters. The results provide insight into the processes in the brash ice channel during freezing and breaking. The paper presents an overview of the tests, measurements and results. The findings from these tests provide an improved understanding of the process in brash ice channel development which can be incorporated into modelling techniques for marine design and operations.
