This paper presents and overview of bergy bit impact trials carried out on the CCGS Terry Fox off the northern tip of the island of Newfoundland in June 18-23, 2001. The trial consisted of impacting target iceberg ice masses ranging from roughly 30 t

In physical modelling, size or scale effects may exist due to the incomplete replication of the relevant details of the prototype. A size effect in ice flexural strenght is evident for experiments and has also been illustrated theoretically. When mod

A series of upward breaking cone tests was conducted at NRC/IMD's ice tank in level ice using EG/AD/S correct density model ice. Cone angles of 45° and 60° were tested. The effect of ice draft velocity in the range 0.005 m/s was studied for ice thi

This paper is a follow-up of a previous study on the interaction between upward-breaking conical structures and level ice in a centrifuge. New data were collected from a series of ten ice sheets grown at an inertial acceleration equivalent to 30 time

This paper describes the experimental set-up and procedures used to model the interaction between level ice, grown from freshwater and saline solutions, and a conical structure in the C-CORE geotechnical centrifuge. A series of ten interactions were

The DART is in upward looking profiler designed and built by C-CORE for the ice tank at the Institute for Marine Dynamics. It utilises a swept frequency or 'chirp' waveform to provide high resolution measurements of the underside of ice rubble. Six p

In 1995 the Canadian Coast Guard initiated a program intended to investigate the recovery of liferafts in extreme seas. This initiative ultimately resulted in a set of three parallel projects, which investigated liferaft behaviour in critical wave co

Progress in determining icebreaking performance from model scale tests is being achieved through a better understanding of the underlying processes. Scaling relationships for full-scale and model-scale ice properties are given, and the implications o
