Over
the last number of years a phenomenon known as
ALWC (Accelerated Low Water Corrosion) also known
as Accelerated Corrosion has been identified as
a problem by a significant number of harbour and
port operators worldwide. Corrosion rates of up
to 3mm/year have been observed and, if not dealt
with promptly can cause millions of dollars worth
of damage to a port or harbour’s infrastructure.
The installation of cathodic
protection (CP) is a proven solution to halt
the corrosion damage caused by ALWC and CP can
be installed as a new build or as a retrofit.
Many operators have little
knowledge of this problem (until it occurs).
Bad advice and poor design, in many instances,
have resulted in expensive remediation programs
having to be undertaken, only to see the problem
re-occurring.
However, ISIS has the experience to provide
our Clients with a complete turnkey approach,
and is able to provide design, supply, installation,
commissioning and maintenance capability for
the successful mitigation of ALWC and corrosion
in general on immersed tubular and sheet wall
steel piling systems.
