Cable Locating and Repair

If you are in need of verifying location of existing underwater cables or need repairs or additional cable protection, we have the personnel and correct equipment for the work. Before attempting to recover an underwater cable it is prudent to determine the present condition of the cable as well identify any other objects that may have been placed over the cable since the original installation. We have the necessary equipment to locate as well as recover buried underwater cables. If your cable is having problems with bottom scouring or damage from vessel activities or ice we will be able to assist you with the best method of adding protection to your cable. This can be in the form of concrete mattresses placed over the cable or split protectors installed on the cable. Sometimes the best solution maybe the placement of rock around and over the cable.
