Abstract:

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 132-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
