ICEBERG - STRUCTURE INTERACTION PROBABILITIES FOR DESIGN

When designing systems to operate in regions through which icebergs tr avel, one of the first inputs of interest is the expected numbers of e ncounters with icebergs. In this paper, geometric solutions are presen ted for a cylindrical gravity-based structure, a floating production v essel, and a cargo vessel. The required inputs are the average areal d ensity of icebergs, the average iceberg water line length, and the ave rage iceberg drift velocity. Example calculations are presented for th e Grand Banks region off Canada's east coast.
