Sunny skies last week on the Côte d’Azur for the successful HDD installation of GRTgaz’s DN100 gas pipeline under the Marseille to Ventimiglia railway line in La Ciotat.
Finding the right drill path was the key challenge for this project, since the crossing is in a residential area with narrow streets, an already congested underground environment and goes through tough grey and yellow sandstone. OPTIMUM mobilised both geological and civil engineers from the outset, from feasibility to works completion, to ensure GRTgaz could safely install the pipe with minimal risk to infrastructure and the rail network. Job done, on time and on budget.
Congratulations to all the teams involved : Gendry, BESSAC-TPC, Sixense
