Project Number 43
Date of Summary March 31, 1985
Subject Ice Forces Against Arctic Offshore Structures
Performing Activity University of Alaska
Principal Investigator Dr. William Sackinger
Contracting Agency U.S. Army Corps of Engineers, Cold Regions Research and Engineering Laboratory
Estimated Completion Complete
Description To determine the lateral forces generated by moving sea ice on artificial islands and offshore structures. This focuses on exploration and development operations in the Beaufort, Chukchi, and Bering Seas. The approach is to measure the effective ice stress at relatively long distances from such islands, to measure the ice displacement simultaneously and to determine the effective island width or structure width during ridge building events. The work is being performed in conjunction with Projects No. 40 and 50.
