Pipelines NW Inc.

YELLOWKNIFE, May 25 /CNW/ - Discovery Air Inc. is pleased to announce that its Great Slave Helicopters (GSH) subsidiary has been awarded a contract to provide helicopter services to Enbridge Pipelines NW Inc. (Enbridge), operator of the liquids pipeline running between Norman Wells, NT, and Zama, Alta.

Commencing July 1, the two-year contract will see GSH fly regular monitoring flights for Enbridge utilizing two AS350BA intermediate aircraft based in Fort Simpson and Norman Wells. The contract includes an option for Enbridge to execute a two-year extension.

"We are extremely happy to have been awarded this contract with Enbridge and look forward to a long and mutually beneficial relationship," said Jeff Denomme, President of GSH. "This contract win is a solid endorsement of our company-wide commitment to safety and customer service."

Through this contract GSH will fly line patrols covering the entire 868-km pipeline right-of-way and associated facilities every other week, as well as providing immediate flights to inspect possible pipeline irregularities should any be detected by Enbridge.

"We are pleased to be assisting Enbridge, a global leader in the pipeline industry, with its operations here in the NWT," said Dave Jennings, President and CEO, Discovery Air Inc. "Enbridge's dedication to safety is very well aligned with that of Discovery Air and our subsidiaries, including GSH."

Servicing the contract will also involve two of GSH's Aboriginal joint-venture partners in the Mackenzie Valley - Dehcho Regional Helicopters and Sahtu Helicopters.

"The opportunity to work with Enbridge is a clear example of how our partnership with GSH helps us achieve more than we could on our own," said JoAnne Deneron, President of Dehcho Regional Helicopters. "We're able to realize benefits from a contract like this which extends beyond the borders of our traditional lands."
