Addiscombe Environmental Consultants Limited has been commissioned to undertake the pre- and post- startup noise surveys on the Nigeria LNG project at Bonny Island, Nigeria.

  • Determination of equipment sound power levels
  • Fenceline monitoring
  • Monitoring at community locations
  • Determination of noise hazardouse areas
  • Generation of in-plant noise contour plots
