CLIENT
Williams Gas Pipelines – Transco
SCOPE OF WORK
Design, supply, and installation of acoustic retrofit for compressor station. The lube oil pipes were isolated to stop the vibration radiating from the structure. A unique system was used to silence the lube oil cooler that resulted in an additional pressure drop of less than 0.016 in. W.G. This pressure drop is significantly less than the typical 0.3 in. W.G. The exhaust stack was treated by sliding silencing baffles into the existing stack. By leaving the original stack in place, considerable cost savings were realized by the client.
ACOUSTICAL REQUIREMENTS
39.6 dBA at 650 ft. from building
NOISE SOURCES
One (1) Solar Mars 100 S Turbine
Original source noise levels: 45 dBA at the NSA (650 ft.)
RESULTS
INNOVA completed all acoustic work to comply with FERC regulations, building retro fit was designed to achieve an effective STC of 49. All acoustic targets were achieved.
