Replacing and rerouting a 50km long gas pipeline and crossing multiple train lines, rivers and motorways in the process is a project that needs expert intervention at every stage.<\/p>\n
When opinion was divided in initial road and rail studies, TER\u00c9GA commissioned OPTIMUM to determine the most appropriate technique for several trenchless sections of the project. Given the coarse alluvium typical of southwestern France, OPTIMUM advised using a DTH hammer rather than a microtunnel, reducing the pipe dimensions from a DN1600 to a DN450 and reducing the depth of the works. OPTIMUM then reworked the project engineering accordingly, ensuring risks were minimised, especially those inherent with railway crossings.<\/p>\n
Reassured by OPTIMUM\u2019s approach and expertise, TER\u00c9GA then also commissioned them to supervise onsite operations for 6 crossings (2 x rail, 2 x river, 2 x road) ; just 12 months later, these crossings are now complete.<\/p>\n
Finding the best solution for every project, without any preconceptions, is how OPTIMUM were able to help TER\u00c9GA reduce the project timeframe significantly and divide the initial drilling cost estimate by 4.<\/p>\n
