7 / Conclusion
Following our experience, we can take in charge all the operations for the installation of the land part of submarine cable projects Or Backhaul cable :
- Survey & Engineering for the coonstruction of duct route -landing station & network telecom link.
- Study of the system earth (Ocean Ground Bed – OGB) : Resistivity measurement – soil study.
- Supply Qualified jointing boxes for submarine or terrestril optical cable – earth or power cable Supply Electrodes & Installation.
- Management of local contractor.
- Installation and Jointing FO cables & copper cables Boxes.
- Acceptance tests : All tests and controls to be performed on optical and copper land cables used at the land part of a submarine link or backhaul cable.
- Shore-end works – Landing operations & Laying of sub-river cable, including supply & installation articulated pipes – burial by jeting up to 20 m water depth – video reporting.
- Training Course.
- Maintenance of existing link.
