For the safe and reliable construction of joints, the UJ Consortium strongly recommends that cable owners check with their marine service provider the qualification status of jointers who will work on their submarine cable system(s) to verify that they have been appropriately trained and are currently in qualification as certified by a UJC training school or one that is formally linked to a UJC training school. Only by doing this can cable owners be sure that jointers have access to the latest processes and techniques, which have been transferred directly to the training schools by the UJ Consortium’s Design Authorities. If in doubt, check the certificate authenticity with the issuing UJC Jointer Training School.
