Summary: | There appears to be considerably less ice scouring inside the ten fathom curve than outside. The decrease is in frequency, width and length, however, there is little decrease in relief of scour. The ten fathom curve acts as a barrier sill to the relatively constant draft ice islands. Although they are grounded during heavy storms and with considerable scour, the ice islands are generally not permanently grounded. The design of any offshore facility on the North Slope must account for ice scour. (Author) |
