Watelet Gas Plant

Calmar, Alberta Canada

PROJECT DESCRIPTION

ATCO Midstream’s Watelet Gas Plant is located 560 m from a farmhouse in rural central Alberta. Noise from the coolers was affecting residents as well as exceeding the 40 dBA nighttime noise level set by the Alberta Energy and Utilities Board (AEUB). The company also planned a plant expansion, so wanted to reduce the noise to a level that would accommodate growth and not bother its neighbours even when the adverse weather would amplify the sound.

SCOPE OF WORK

INNOVA conducted diagnostic noise measurements and acoustically treated two radiator coolers, an amine cooler, and a propane cooler. The acoustic treatment of the coolers involved the design and installation of:

  • acoustic baffles
  • acoustic barrier walls

ACOUSTICAL REQUIREMENTS

40 dBA nighttime noise level set by the Alberta Energy and Utilities Board (AEUB)

SILENCING SOLUTIONS

ATCO Midstream contracted INNOVA to measure existing noise levels and design a treatment for the individual noise sources. The acoustic design achieved 35 dBA at the nearest sensitive receiver under wind-neutral conditions. Post-construction measurements confirmed the noise reduction.
