DESIGN OF A COMBINATION BUBBLER-GUIDANCE SYSTEM TO BE INSTALLED IN WHITEFISH BAY, MICHIGAN

The U. S. Coast Guard and U. S. Army Corps of Engineers selected the navigation channel at the Whitefish Bay end of the St. Marys River for the installation of a combined bubbler-wire guidance system. This system is to extend the navigation season on the Great Lakes by retarding the formation of ice and by providing a navigation aid. Support equipment will be installed on Point Iroquois, Michigan. Laboratory tests and engineering analysis showed that the bubbler line should be 3 miles long and composed of PVC pipe with 1/32-inch orifices every 15 feet. The wire-guidance system will be 7 miles long and use NO. 4 AWG insulated cable with a 1-kw, 400-hertz signal generator. The report contains engineering descriptions, design details, and cost estimates necessary for installing the bubbler-wire guidance system. (Author)
