Great Lakes Shipyard completes tug for New York

摘要

The first of two 45' twin-screw 940-hp steel tugboats was delivered to the New York Power Authority (NYPA) in October. The Daniel Joncaire Ⅱ will help keep Niagara River water intake structures for the Niagara Hydroelectric Power Plant and the Sir Adam Beck Pumped Generating Station (owned by Ontario Power Generation) clear of ice blockages during the winter. Designed by the Bristol Harbor Group Inc., Bristol, R.I., and built by Great Lakes Shipyard, Cleveland, the 45'×l9'7"×6'l" Daniel Joncaire Ⅱ is designed to operate in the ice of eastern Lake Erie, where the waters flow into the Niagara River and hydroelectric plants. The tugs will be used to install and remove an 8,800' floating ice boom, consisting of steel pontoons linked together and anchored to the river bottom at Lake Erie's outlet to the Niagara River. Bill Jordan, senior naval architect at Bristol Harbor Group, said designers sought to strike "a balance that fulfills the demands of all the competing criteria," and be environmentally friendly.
