Ensuring the integrity of our pipeline assets is one of our main objectives when we talk about our safety as a core value. It becomes a challenge when we must make it real in our 92,600 km (57,500 miles) network of natural gas pipelines. These plastic slabs are just as efficient as concrete to avoid third-party mechanical, but with additional benefits. Its high visibility colour allows our patrolling team to easily spot any exposed section in the pipeline and quickly reveals the existence of a high-pressure pipeline to any third party performing unauthorized activities over the pipeline.
