Case Study - Compressor & Auxiliary Buildings

Pineland Compressor & Auxiliary Buildings

Summary:

These new compressor and auxiliary buildings are part of a pipeline expansion project located in Texas. USSI engineered the compressor building to mitigate equipment noise within strict specified sound levels of no more than 55 dB(A) Ldn (equivalent to a continuous 48.6 dB(A) Leq) at the nearest noise sensitive area (NSA). The compressor building houses a Solar Titan 130S turbine driving a Solar C652 compressor. The ventilation system was designed to provide the specified air change rate and meet acoustical performance criteria. Acoustical silencers were utilized on the wall supply and roof ventilators to limit building and fan noise to less than 65 dB(A) measured 12 feet from the opening. The exterior walk doors and equipment door were selected to satisfy the balanced noise mitigation design. The auxiliary building also met the acoustical and mechanical design criteria with similar construction.
