  • IPC Panel Session Addresses Industry Collaboration
    BROUGHT TO YOU BY THURSDAY 29 SEPTEMBER 2016 IPC panel session addresses industry collaboration Yesterday during the Executive Panel Session, six pipeline industry leaders gathered to discuss how organisations can change the mindset of incremental improvements to a culture that is focused on disruptive innovation. The session was moderated by IPC Conference Chair and Senior Vice President, Technical Services – Dynamic Risk Patrick Vieth and Vice President of ROSEN USA, Mexico & Central America Chris Yoxall. The panel members for the session were Milton Altenberg (Quest Integrity Group), Jason Sharpe (ATCO Pipelines), Ken Paulson (BC Oil and Gas Commission), Chris Bloomer (Canadian Energy Pipeline Association); Honorable Christopher A. Hart (National Transportation Safety Board), and Walter Kresic (Enbridge). A number of topics were covered in the session, with each segment prefaced by a live audience poll on a pertinent question for the pipeline industry. One of these questions was “Can stakeholders initiate industry collaborations and still maintain public trust?” While there was no clear-cut answer to this question, the responses from the audience pointed toward the positive elements of industry collaboration, DON’T MISS with most respondents saying that it was possible to collaborate and maintain public trust. The panellists agreed, and several members emphasising that the key to successful collaboration was transparency and trust. THE IPC 2016 The event was well attended and it was clearly a valuable event for the industry as a whole. NEWSLETTER ON FRIDAY! Jay Ingram speaks at IPC Delegate Luncheon The IPC Delegate Luncheon, held on Wednesday afternoon at the Hyatt Imperial Ballroom, provided an opportunity to reflect on the importance of science literacy in the general public, with science writer and broadcaster Jay Ingram addressing the attendees and speaking on the growing elitism associated with scientific literacy and the damage this is doing to public perceptions of companies working in the engineering sector.

    Westcoast Energy Inc. Westcoast Energy Inc. fonds. – 1897-2002, predominant 1949-2002. 5.2 m of textual records and other material. Administrative History: Headquartered in Vancouver, British Columbia, Westcoast Energy Inc. is a natural gas company with operations across North America and interests in international energy companies. Its main activities include natural gas gathering, processing, transmission, storage, distribution and marketing, as well as power generation and other energy services services. Its predecessor company, Westcoast Transmission Company Limited, was incorporated by a special act of Parliament in 1949. It was established by Frank McMahon, an oilman who had began Alberta company West Turner Petroleums in 1936 with his brothers George and John. After making a substantial oil strike in 1939, McMahon purchased two smaller companies and merged them with West Turner in 1947 to form a holding company called Pacific Petroleums. That year, the company was drilling in Leduc, Alberta and made a huge oil strike which ignited, creating a huge fire. The publicity received by the fire generated a lot of investor income for “Pacific Pete,” and McMahon used this money to form Westcoast Transmission Company Limited, a natural gas company. Westcoast Transmission received government approval to construct, at Taylor, B.C., a 1,046-kilometre, 30-inch mainline natural pipeline, the first “big inch” pipeline in Canada, and the first natural gas processing plant in British Columbia. Construction on the pipeline began in 1955, and when completed in 1957, natural gas flowed at a rate of 400 million cubic feet per day, from Northeast British Columbia to the Canada-U.S.

The NEB approach to regulation of access to pipelines has changed over time as oil and gas markets have changed. Originally, oil pipelines were entirely common carriers. In the last fifteen years, the NEB has approved new oil pipelines in which the majority of capacity is subject to firm contracts, provided that certain conditions are met.
