UEP och ELFE measure system

Water Electric Potentials (UEP) are produced by cathodic currents in the ship or submarine hull and also from propellers or other metallic materials in contact with salt water. 

A vessel's electrical potential signature is therefore distributed in a similar manner to the magnetic signature. This can also be used as an input signal or trigger signal in an influence mine. The vessel's movements also produce an additional Low Frequency Electric field (ELFE) that can be used for positioning, targeting or surveying.

Polyamp has designed a series of sensors and platforms for measuring these underwater electrical signatures for use in:

  • Oil and gas map applications
  • Upgrading conventional sea areas
  • Transportable sea areas
  • Surveillance, fixed or mobile equipment mines influence oceans
  • Part of the Harbour protection system
  • Environmental assessment system
    • (eg, wave, earthquake, ionospheric noise)
