BULLWINKLE OIL PLATFORM

Bullwinkle is a 1,736-foot tall, pile supported fixed steel oil platform in the Gulf of Mexico. Of the total height, 1,352 feet are below the waterline. It is located in Green Canyon Block 65, approximately 160 miles southwest of New Orleans. Bullwinkle is the world’s tallest supported fixed steel structure. The tower is designed to resist hurricane force winds, 70’ waves, and a lifetime of stress-reversals induced by small waves. Bullwinkle used 10 times the amount of steel as the Eiffel Tower and weighed over 50,000 tons. In order to tow it out to sea, an 853-foot long barge, the world’s largest at the time, had to be constructed.

DUQUESNE BREWERY CLOCK – PITTSBURGH, PA

 

Located on Duquesne Brewing Company building in Pittsburgh, Pennsylvania, the Duquesne Brewery Clock has the largest clock face in the United States. When it was installed in 1933, it was the largest single-face clock in the world. The 60-by-60-foot clock face, with a 35-foot minute hand and a 25-foot hour hand, both of laminated aluminum, is nearly twice the size of London’s Big Ben. Originally located on a Mount Washington hillside, the clock’s face has been used as advertising for a succession of businesses. Most recently, AT&T took over the rights to advertise on the clock and redesigned the face to display the traditional blue and white AT&T logo.
