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.
