Cathodic Protection can be achieved by Impressed Current Cathodic
Protection (ICCP) System for a solution to the CORROSION
problems encountered on the underwater structures (Hull) of the
ship by means of a Rectifier supplying Regulated Direct Current
to Permanent Anodes in relation to the Reference Cell which proves
the Current Density between - 600mV to - 850mV measured against
a Silver/ Silver Chlorite (Ag / AgCI) Reference Cell or +350mV to
+250mV measured against Zinc Reference Cell.
Evaluation on the condition of both Permanent Anodes and the Reference
Cell can be verified electrically with reference to Hull U in the
following range:
|
Silver/ Silver Chlorite (Ag / AgCI) Cell
|
|
- 850mV
|
|
|
|
- 950mV
|
|
Zinc(Zn) Reference Cell
|
|
+ 350mV
|
|
|
|
+ 250mV
|
Our Engineers have been in the service of the Catholdic Protection
Systems on vessels and are able to provide these services:
- Cathodic Protection (ICCP) Design
- Evaluation and Analyzing Existing CP System
- Corrosion Assessment with Coatings
Criterion for Cathodic Protection is necessary to polarize
the local areas to the potential of adjacent Anodic areas.
