Noise Solutions Achieves Zero Net Increase in Noise
Hunt Oil Company, a privately held exploration and production company with operations in North and South America, Europe, Australia and the Middle East, had plans to install more than 1400 HP of gas compression within its inlet facility on Shell’s Caroline Gas Plant based, near Sundre in Alberta, Canada. Hearing about Noise Solutions unparalleled products and services, Hunt Oil chose the company to carry out the challenging task of adding zero noise to the site, which was mandated by Alberta’s Energy Utilities Board (now Alberta Energy Regulator) and the Sundre Petroleum Operators Group (SPOG).
When the installation of Hunt Oil’s powerful gas compressor was proposed, the Sundre-Caroline community expressed unease with the site development, but both Hunt Oil and Noise Solutions were committed to achieving the goal of zero noise and zero impact to the community. Also adding to the challenge was the sour gas on site, which meant the ventilation system would need to be completely reworked, and the entire noise suppression unit would need to be custom designed to compensate for the sheer size of the compressor building.
To effectively attenuate the high frequency noise and the challenging low frequency noise of the new compressor unit, Noise Solutions and Hunt Oil agreed that complete sound-suppression would be necessary and the challenges continued to grow. The Air-X-Changers 168EF Cooler had a 14 foot diameter fan – the largest Noise Solutions had ever worked on. This posed both design and shipping challenges. To remedy the noise produced by this fan, Noise Solutions used a customized Cooler Fan Silencer Package, including a Cooler Inlet and Outlet Silencer and Cooler Plenum Walls to trap any noise that could potentially escape.
The compressor engine, a Waukesha L5794LT at 1,445 HP, was also equipped with customized Noise Suppression Equipment. This included a full Zeron® Engine Exhaust Silencer package, Induced Draft Acoustical Building Inlet Ventilation and Fan Forced Acoustical Building Outlet Ventilation, as well as an Acoustical Building Enclosure. The combination of this powerful Noise Solutions equipment achieved the goal of zero noise, meeting all regulations.
With a job of this scope, open communication and calculated attention to detail is of utmost importance. Noise Solutions rose to the challenge and provided Hunt Oil with the quality products and service it’s known for.
Several parts of equipment were custom-designed to effectively meet the requirements of Hunt’s machinery. Noise Solutions direct and amenable approach to the challenges faced at Hunt Oil’s Caroline Gas Compressor site allowed for quick and efficient shipping, delivery and installation, to fully meet and surpass the regulations set forth by SPOG and the EUB. This resulted in a final dBA of 39.5, a zero noise impact and complete success of the project.
