Safety is our number one value

Investing in pipeline safety

One of the best demonstrations of our commitment to safety is our long-standing and ongoing Pipeline Integrity Program. 这一年度流程保持了我们管道系统的完整性、安全性和可靠性. Our process includes:

• Risk assessment
• Threat identification and evaluation
• Integrity monitoring to detect pipeline anomalies
• 通过检查和维修解决管道异常
• 对管道进行额外的监测、调查挖掘和工程评估
• Review and learning.

On top of this program, every kilometre/mile of pipeline, pump, 压缩机设施或发电站采用成熟的技术和集成, industry-leading safety systems. Once constructed, 所有管道和设施都受到持续监控, whether that’s from inside the pipe, on the ground or from the air.

Preventing pipeline leaks from end to end

Leak prevention is a top priority. 这就是为什么我们采取重大措施，以防止泄漏的机会之前, 在我们的管道和设施使用期间和之后.

It begins during construction, with each joint of pipe being factory coated with high-performance coatings and carefully transported to the project location. Each individual weld is inspected using radiographic or ultrasonic techniques to ensure the highest quality welding. Qualified onsite inspectors visually inspect every phase of the installation process including lowering the pipe into the ditch, and then backfilling.

Once installed, a low voltage electrical current is applied to the pipeline to prevent corrosion and the pipe is tested with water (hydrostatic testing), 加压到比操作过程中所经历的更高的水平. In the unlikely event of an incident, TC能源全权负责应急响应, clean-up and costs.

Proactive detection

24 hours per day, 365 days a year, our Operations Control Centres (OCCs) manage some of the world’s most sophisticated pipeline monitoring technology.

At sites throughout North America, 我们进行从空中巡逻(使用低空飞行的飞机和灵敏的探测设备), to geotechnical monitoring and searches for areas where erosion may have washed away the soil covering a pipeline.

在线检查也是我们日常工作的一部分. Also known as 'pigging,' (Pipeline Inspection Gauge) these inspections use an internal inspection device called a 'smart-pig' to travel the length of a pipeline to collect data to monitor the condition of the pipeline. 当在线检查发现潜在的异常时, 还可以进行调查挖掘，以暴露异常，以便进一步检查和可能的修复.

这条线路是否运输天然气、石油和液体, 在潜在的问题或不正常的第一个迹象, OCC operators stop pipeline flow within minutes, 隔离问题，帮助保护自然环境.

By partnering with industry peers, universities, colleges and governments, 我们是业内最大的研发项目之一的一部分. In fact, 自2013年以来，我们已投资超过1.5亿美元用于研究和创新，以提高安全性, integrity and quality in our industry.

作为我们环境管理承诺的一部分, 在努力满足北美能源需求的同时，我们努力将对环境的影响降到最低. We invest heavily in understanding the impacts our pipelines and facilities have on sensitive wildlife species and work to preserve and protect ecosystems throughout North America.
