News: LONG TERM MAGNETISING OF SUBMARINE POWER CABLES PROVEN BY INNOVATUM LTD

  • Magnetising the cable is a very low cost option, which may be considered as a long term insurance. The cost of magnetising a cable is much less than the cost of a single day of Cable Maintenance vessel time.
  • The Cable was magnetised in April 2011 and commissioned in 2012 and carries 3 phase power to shore at 132 KV.
  • The latest testing used the same Passive Magnetic tracking system, and also confirmed the data using the AC tracking method.
  • The data was the same as the data acquired in 2012 at the same place.
  • The cable was magnetised prior to lay, using the Innovatum process, and surveyed using Passive Magnetic techniques before power was applied.
  • This testing shows the magnetic signal is not degraded by time or power currents in the cables. Cables may be located, tracked and surveyed using Innovatum methods without the need to de-energise the cable.
  • Only Innovatum SMARTRAK can be used to locate and survey power cables using both Passive Magnetics, the AC power signal, or tone tracking in one system.
