Following the successful completion of tunneling operations, the operational condition of the tunneling equipment may vary significantly across different projects. Therefore, a comprehensive technical inspection shall be conducted as the primary step to evaluate the performance of the machine and its individual components. In accordance with predefined protocols, systematic inspections are carried out, with necessary technical support such as main bearing endoscopy provided when required. Based on the inspection results, professional recommendations shall be formulated regarding the repair, reuse, and optimization of the machine and its components. For most utility tunneling machines, professional refurbishment integrated with targeted technical upgrades is deemed the optimal solution. For large-diameter TBMs, worn or non-serviceable components shall be scrapped on-site, while high-value components shall be transported back to the manufacturer for professional rebuilding and restoration.

Upon your request, we can restore your machine to optimal condition and prepare it for its next operational phase. In close partnership with our clients, CREG formulates a detailed cost estimate and a dependable timeline for systematic equipment refurbishment. This comprehensive service encompasses additional engineering design, process planning, as well as a clear list of required professional personnel, spare parts and wear components. Needless to say, we can also take into account the project-specific requirements of your planned follow-up project and make corresponding modifications to the equipment. Upon completion of the refurbishment work, you will also be provided with an official OEM certificate, which verifies the professional renovation of your CREG TBM. Refurbishment services can be carried out at CREG headquarters, our international service centers, your own workshop, or directly on-site for larger TBMs.
