Safety is our number one value

Investing in pipeline safety

我们对安全承诺的最佳证明之一是我们长期持续的管道完整性计划. This annual process maintains the integrity, safety and reliable operations of our pipeline systems. Our process includes:

• Risk assessment
• Threat identification and evaluation
• Integrity monitoring to detect pipeline anomalies
• Addressing pipeline anomalies through inspections and repairs
• Additional monitoring, investigative excavation of the pipelines and engineering assessments
• Review and learning.

On top of this program, every kilometre/mile of pipeline, pump, compressor facility or generating station is made using proven technology and integrated, industry-leading safety systems. Once constructed, all pipelines and facilities are monitored constantly, 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. That’s why we take significant steps to prevent the chances of leaks before, during and after our pipelines and facilities are in use.

It begins during construction, 管道的每个连接处都在工厂涂上高性能涂料，然后小心翼翼地运到项目地点. 每个单独的焊缝都使用射线照相或超声波技术进行检查，以确保最高质量的焊接. 合格的现场检查员目视检查安装过程的每个阶段，包括将管道放入沟里, and then backfilling.

Once installed, 对管道施加低压电流以防止腐蚀，并对管道进行水测试(水压测试)。, pressurized to a higher level than would be experienced during operation. In the unlikely event of an incident, TC Energy takes full responsibility for emergency response, clean-up and costs.

Proactive detection

24 hours per day, 365 days a year, 我们的运营控制中心(occ)管理着一些世界上最复杂的管道监测技术.

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), 到地质技术监测和搜索可能被侵蚀冲走覆盖管道的土壤的区域.

In-line inspections are also part of our regular routine. Also known as 'pigging,这些检查使用一种称为“智能清管器”的内部检查设备，沿着管道的长度收集数据，监测管道的状况. When an in-line inspection identifies a potential anomaly, 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.

Whether the line carries natural gas or oil and liquids, at the first sign of a potential issue or irregularity, OCC operators stop pipeline flow within minutes, isolating the issue and helping protect the natural environment.

By partnering with industry peers, universities, colleges and governments, we’re part of one of the industry’s largest research and development programs. In fact, since 2013 we have invested more than $150 million towards research and innovation to advance safety, integrity and quality in our industry.

As part of our commitment to environmental stewardship, 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. 我们投入巨资了解我们的管道和设施对敏感野生物种的影响，并努力保护整个北美的生态系统.
