Galebreaker supplied a solution to provide sound attenuation screens to reduce the sound to an acceptable level.
The Challenge
Portable rental package cooling towers were installed along a river to provide supplemental cooling to an adjacent Power Plant. Approximately 1/2 mile away there was a sub-division which was complaining about the noise generated by the towers. Each of the portable towers supplied by Aggreko required screens to reduce the noise.
The Solution
Galebreaker supplied a solution to provide sound attenuation screens to reduce the sound to an acceptable level. Each tower required (12) screens totalling 744 square feet or 69.12 square meters. There were (12) towers so a total of 8,928 square feet or 829.44 square meters were installed at the facility. Aggreko designed steel frames to support the screens and took responsibility for all support design and installation. The screens were installed on a slant to direct the sound out of the stacks to the highest possible elevation. The screens were eyeletted for easy attachment.
The Benefits
The delivery and installation was on a very compressed schedule. Galebreaker met their delivery requirements but the installation proved to be a bit more difficult so insltallation was slower than expected. A sound test had been completed before and after the installatiion of the screens. Aggreko and the residents nearby were very pleased with the results. The facility was in danger of a law suit from the residents but after the sound attentuation was installed, those threats were dropped.
