INTEGRATED REPORT 2023

The security of our network 

For GRTgaz, the security of its facilities and information systems is a permanent and crucial objective. This is a key factor in performance and risk prevention and management within the company.

Industrial risk is controlled through the implementation of prevention, maintenance and monitoring policies under the ministerial order governing the integrity of gas transmission pipelines. These policies are based on both regular monitoring of our linear infrastructure, using a combination of on-the-ground and aerial resources, and on ten-yearly inspections combined with repairs to guarantee that our installations remain fit for service over the long term. Management is carried out via a security management system incorporating governance at every level of the company.

In terms of pipework inspections and maintenance, GRTgaz easily exceeded its target in 2023, with 9,500 km of pipework having its fitness for service renewed since 2021. 2023 was the second full year marked by more frequent inspections with pistons62 and systematic leak searches (carried out by teams on foot, in vehicles and by air, including drones). This year also saw the development of our remote monitoring system for the cathodic protection63 of our infrastructure and the recording of press cycles.

The very ambitious target for third-party attacks on pipelines was not achieved, with four thirdparty incidents involving pipelines this year. The number of events recorded is still down on the values seen in the previous four years, however. These incidents were all analysed and repaired quickly by GRTgaz teams.
