Gas transportRoques-Goyrans


The pipelines constructed in the 60s and 70s linking the shut-off stations in Roques and Goyrans present anomalies (insufficient depth, restrictions, elbows, flood risk area) that expose them to risks of external damage and do not allow smart pig inspection.


  • Modernisation of the Roques shut-off station to allow maintenance by swabbing
  • Movement of the Goyrans shut-off station outside the areas at risk of flooding from the Ariège.
  • Reconstruction of two pipelines under the Garonne and Ariège using the directional boring technique over a combined length of around 3.1 km with nominal diameters of 150 and 300 mm
