Hyperbolic Cooling Towers - Somerset (Brayton Point), Mass.
Dominion Virginia Power
Design and Construction
Ibberson was a joint venture partner for this Environmental Protection Agency mandated project to convert the Brayton Point Station in Somerset, Massachusetts, from an open cooling system to a closed loop cooling system.
The cooling tower construction contains over 3,900 cubic yards of concrete and 488,000 lbs. of reinforcing steel. Each cooling tower is 500 feet tall and will be about 370 feet wide at the bottom with concrete walls 20 inches thick. The cooling tower’s varying shape required flexible formwork for the changing diameters of the tower.
When complete, four 4,900 hoursepower pumps will drive 360,000 gallons of water per minute into each of the towers.
