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.
