In a joint venture MAX STREICHER GmbH & Co. KG aA carried out parts of the pipeline project "Val de Saône". STREICHER was responsible for lot 4 east of Dijon, Bourgogne/France. Client was GRTgaz, SA.
Lot 4 extended over a length of approx. 36 km. The pipeline has a diameter of 48". Due to mainly coarse gravel soil, dewatering with deep wells was necessary. In detail this meant the installation of 1,250 deep wells and 8 km 32" water discharge lines, covering a total of 12.5 km pipeline trench. Besides the laying of the pipeline, the contract included the execution of several microtunnel crossings and valve stations.
This pipeline with a total length of 190 km is part of the project „Val de Saône“ of GRTgaz. Within this project, several hubs were executed and the compressor stations in Voisines, Palleau and Etrez were expanded. The objective is to ensure the national gas supply as well as distribution and especially develop the North-South direction of the gas transport in France.
