| Description |
This was a Joint
Industry Project (JIP) with the Minerals Management Service and the Canadian National
Energy Board. The objective was to better understand flow fracture as a load limiting
mechanism for Arctic platforms using large scale experiments. The first phase of the
program consisted experimenting with different field techniques and developing new
instrumentation for the precise measurement of ice fracture parameters. The second phase
examined a series of field fractures under complex loading conditions. Two field programs
were conducted. The first was in a fresh water lake to study fractures under different
scales and under stable and unstable conditions. The second investigated the fracture of
first year sea ice at full thickness under several loading conditions. A theoretical ice
flow splitting model was tested and compared with laboratory data. |
