FEATURE ARTICLE
Wartsilla is a leading supplier of ship-borne degaussing systems
for all kinds of surface vessels and submarines. Its systems
cover the full range of magnetic silencing for all types of naval
vessels including for magnetic protection against the hazard of
magnetic sea mines, depicted above. It has provided more than
220 systems for various navies.

Another provider
of degaussing
systems is the L3
Power Paragon unit
of L3Harris Technologies. Its Advanced Degaussing System, for
example, provides
controlled current
to independent degaussing coils embedded throughout
the hull of a ship.
The Bipolar Amplifier Units (BPAU's)
provide precise
current required to
create composite
magnetic fields that
oppose and neuL3Harris degausser
tralize the ship's
magnetic signature
as it moves across
the waters. These fields are formed by the BPAUs controlling the
polarity and intensity of current flow through each degaussing
coil. The BPAU's monitor their functional status and status of the
coils they are driving.
