For the branch connection

GRTgaz determines and carries out the operating and preventive and corrective maintenance operations for the branch connection. These operations consist of:

Surveillance
GRTgaz continuously monitors the branch connection and its entire network remotely by transmission of flow rate and pressure measurements. GRTgaz also undertakes field surveillance on foot, in vehicles and by overflying network structures.

Inspection
GRTgaz implements a voluntary inspection and repair programme for its pipelines, based on:

  • inspecting pipelines using a pig carrying instrumentation to check the integrity of the pipeline where technically feasible
  • searching and locating damage to coatings using 'surface electrical' measurements
  • analysing the efficacy of cathodic protection
  • Combined, these methods ensure the pipeline has a long service life.

 
Cathodic protection
GRTgaz protects its underground pipelines from corrosion.

Section repair and/or replacement
When damage is identified, GRTgaz makes repairs to the branch connection as quickly as possible: fitting a sleeve or replacing the affected pipeline.

These operations are included in the transport routing price with effect from 01/01/2017
