Minnesota Refinery Selects TETRA System from PowerTrunk, Bay Electronics
Wednesday, May 31, 2017 | Comments

Flint Hills Resources Pine Bend, a producer of transportation fuels, will deploy a digital TETRA radio communications network for its refinery operations located in Rosemount, Minnesota. Provided by PowerTrunk, the network will be the first TETRA system for the petrochemical sector in North America, a statement said.

The Flint Hills Resources Pine Bend Refinery has a radio population of about 4,000 users. The refinery covers about 1,000 acres and has a production capacity of 339,000 barrels per day.

Bay Electronics, working with PowerTrunk, will provide the refinery complex with a complete $3 million communications system consisting of multiple radio sites with diversity receivers, fully redundant control equipment, antenna towers, protective shelters, generators, in-building antenna systems, desktop radios, and the latest intrinsically safe TETRA portable radios with remote speaker microphones.

“Mission-critical communications that keep our employees connected at all times are essential to maintaining safe operations,” said John Bowman, digital lead, Flint Hills Resources. “The solution we chose includes intrinsically safe radios that are designed to provide crisp and clear audio in the noisiest workplace environments and are equipped with GPS, dynamic group and profile management, and other advanced features to enable a safer and more efficient workforce anywhere on our complex.”

The two-site system operates on Part 22 channels and some Part 90 channels with about five channels per site. There will be 32 analog channels tied into the TETRA system through a gateway. Multiple bidirectional amplifiers (BDAs) will ensure coverage for the entire complex.

“We believe our operations are best served by solutions that are based on open industry standards,” said Mark Murphy, project manager, Flint Hills Resources. “The TETRA solution was selected in part because it is the leading open standard digital radio communications technology in use around the world, and it will allow Flint Hills Resources to leverage the best practices in digital radio solutions in a complete and cost-effective manner.”

“Bay Electronics has long been a proponent for TETRA in North America and is pleased to bring TETRA technology to Flint Hills Resources,” said Rick Nielson, president of Bay Electronics.
