Project Owner:
Northern Natural Gas

Completion Date: 2005

The NNG Engineering department was directed to upgrade all fire and gas detection systems at their compressor stations across a 7 state region. NNG requested engineering and design support for the design of the new fire and gas detection system and the interface with the emergency site shutdown system (ESD).

Beaver Station is an eight compressor, two building station. The existing rising gas ESD system was maintained and monitored by the new system, along with the addition of manual pushbuttons located by the exits of the compressor buildings. UPS systems were used for emergency backup power for turbine shutdown controllers and emergency egress lighting.

Construction was scheduled for the summer months to minimize natural gas distribution disruptions. Design was a fast track repeatable concept at each station to minimize parts on hand and simplicity when employees were required to work more than one station.
