The French company Geosel (Geostock),specialists in underground hydrocarbon storage,entrusted the maintenance of the GSM 2 Sud pipeline to Prezioso Linjebygg, world leader in engineering and technical services, principally for the petrol and gas and power generation sectors. Géosel called upon Prezioso Linjebygg to provide expert teams and a high-quality service for the blasting of a rather complicated structure. The pipeline, located between the Berre and CITIS lagoons (municipality of Istres), runs through a narrow, closed tunnel, 900-metres long, and not accessible to the public. The mission consisted of blasting 1,600m2 of pipes with 84 supports – a formidable challenge for Prezioso Linjebygg and Phenics who finally found success at the end of the tunnel!
