Composite Material Noise Reduction Enclosure

DIAB International has designed an alternative to the insulated steel enclosures typically used for noise reduction around working equipment such as pumps, motors, and machinery on offshore platforms. A steel enclosure can weigh more than 20,000 lbs. A noise enclosure made of composite material weighs in at half that weight, the company said. The enclosure combines a Divinycell P core at a thickness that provides the required panel strength and sound insulation with fiberglass laminate skins made with a fire-retardant resin. To surround the equipment, custom-sized panels are bolted together and mounted to the platform floor in a steel frame. The company reported noise reductions from 114 dB inside an enclosure to below 70 dB outside of the enclosure.
