摘要：	This report provides the results of a study to assess the applicability of ice boom technology to aid or extend oil spill cleanup capabilities in broken ice. The technology has been developed and used successfully at several locations to control the ice. For oil spill cleanup in broken ice, booms have the potential in a number of ways, such as: (a) preventing ice ingress into the spill area, thereby providing an ice-free area where conventional oil spill equipment can operate; and, (b) providing a means to assist in separating the oil from the ice. Ice booms may have the potential to assist in many of the scenarios defined in the Alaska Clean Seas Technical Manual. Ice booms, in combination with the available support vessels on the North Slope, are expected to be applicable to oil cleanup in moderate broken ice conditions of up to about 50%. Booms are also expected to be applicable for some cases in higher ice concentrations of up to 70%. However, larger vessels with more power, such as icebreakers, would be required for a wide operating envelope. Prototype tests should be carried out in the Alaskan Beaufort Sea as the next step in advancing this technology for reliable usage in oil spill cleanup situations in broken ice in the Arctic. It is believed that quite conservative assumptions were made in this project in establishing the loads on the boom, particularly with respect to the under-ice currents at the boom, and their colinearity with the winds. This was necessary because very little data are available for this case. Field measurements would be valuable to improve the estimates made here. A field deployment should be conducted offshore of Prudhoe Bay using a boom of limited size. A boom with two 500 ft (150 m) spans should be built and deployed using the available support vessels in the chevron and catenary configurations. / Supplementary Notes: Sponsored by Minerals Management Service, Herndon, VA. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
