| Description |
The objective was to determine
the response of spray ice barriers and spray ice islands to environmental forcing
functions. This study used photogrammetric analysis to quantify the original geometry of
the spray ice barrier placed around Exxon's CIDS Platform, during the winter of 1984; and
to determine how the barrier reacted to ice movements. The analysis included a
quantification of the frequency and magnitude of winter ice movements and the amount of
erosion of the spray ice barrier during the pre-breakup and post-breakup periods. This
information is necessary to determine the reliability of spray ice as a protective barrier
for platforms. |
