Temporary drilling rig and directional drilling operation sound walls typically range in height from 16 to 32 feet and can be installed on one, two, three or all four sides of a drilling rig and associated support equipment to meet the sound control requirements of the site. ENC’s STC-25 modular acoustical temporary rig noise control system is designed to effectively block drilling rig related noise from propagating into the surrounding environment while allowing for quick and efficient installation and removal. Typically, the temporary sound walls are installed at the perimeter of the drill site between the noise generating drilling equipment and the sensitive off-site noise receptors. For optimum temporary rig noise control, the sound walls and noise barrier walls should be positioned as close as possible to the noise sources while allowing for access and adequate airflow. Our STC-25 rated sound wall panels typically reduce equipment noise levels 15 to 22 dBA on the sides of the equipment where the wall is installed. All temporary drilling rig sound walls are pre-engineered to meet or exceed IBC wind and seismic loading requirements.
The ENC sound wall panel system is constructed with 8 foot high by 20 foot long steel frames with 8 foot high by 20 foot long STC-25 acoustical blankets mounted on each frame. Each blanket panel has a 1 foot wide sealing flap on the bottom and on one side to provide acoustical sealing with the adjacent panels when installed. The noise barrier walls can be installed one panel high (8′ high), two panels high (16′ high), three panels high (24′ high), or four panels high (32’ high) and affixed to steel support poles or I-beams installed on 10 foot centers. The acoustical panels are connected to the vertical support structures with specially designed connectors that allow quick installation and removal.
Where site conditions do not allow for auguring of structural support, ENC offers a “K” rail supported temporary rig noise control system.
