创造性的工程解决方案，成功的跨水项目

Although fish may love a major flood because of their new-found access to more food, 营养和生境, 人员和管道就不是这样了.

In June 2013, heavy rainfall triggered catastrophic flooding in major southern Alberta rivers. The one-in-200-year flood exposed four of the natural gas pipelines on our NGTL系统 where they cross the rivers – creating a potential issue that needed to be addressed.

“We didn’t want to pull a completely safe pipeline out of the river to reinstall it deeper in the river bed because it causes ground disturbance, potential environmental effects and disruption of service to our customers. 威尼斯电玩城手游以为会有更好的办法,Kim Ogilvie说, the manager of environmental planning and permitting for pipeline 完整性 projects in Canada.

After discussions with engineering experts about successful best practices, alternative solutions were proposed that would protect the pipelines while minimizing the company’s environmental footprint.

到目前为止, TransCanada的工程解决方案取得了成功, with the provincial regulator approving the engineering practices as a permanent solution.

金说, “有时候，这需要一点创造力, 一些聪明的工程和大量的合作来做一些很酷的事情.”

重新治理河流

The project team used a mix of soft engineering and bioengineering practices to “re-train” the river – essentially giving the river new engineering skills to help it do a different job.

在一个案例中, Simonette河管道修复项目, groynes were built to deflect water away from the river bank to prevent further erosion – which is what originally exposed the pipeline. 而不是, 山沟把水流引回原来的路径, 所以碎片和沉积物会沉积在后漩涡中, 从而加固被侵蚀的河岸，为鱼类建立新的栖息地.

Fish habitat enhancements were also constructed to make up for the potential loss of habitat while the river recovered.

“These types of river training works are established and acceptable practices and have been adapted for other kinds of water issues, 不仅仅是管道,金说。. “但这是横加公司第一次真正涉足这一领域. 威尼斯电玩城手游也学到了很多.”

在另一个项目中，TransCanada公司创建了一个通道内窗台. A trench was constructed downstream of the pipeline and filled with rock so that the depth of cover over the pipeline would increase as the river naturally picked up and deposited granular material at the sill.

自从修复了暴露的管道, TransCanada has monitored the effectiveness of the pipeline protection projects within the company’s routine surveillance monitoring program and recently submitted a monitoring plan and report to the regulator that has since been approved.

指导原则

今年早些时候，环境团队引入了一套 指导原则 that outline the way the company approaches environmental management and conducts activities throughout the life cycle of our assets.

“We talk a lot about being responsible environmental stewards of the land we share – so this was our chance to demonstrate all three pillars of the principles – stewardship, 保护和性能-在行动,金说。.

“Essentially, this is an initiative about pipeline safety and environmental protection co-existing. We were able to demonstrate that our innovative solutions are a safe and responsible way of addressing challenges.”
