Design of cathodic protection for harbours

Corrosion represents an inevitable factor which engineers and marine contractors must consider when designing, installing or working around harbour structures.

Sheet piling and tubular support piles come under attack from continuous exposure to seawater with plenty of oxygen present. The corrosion rates for these structures may be particularly high as a result of a phenomenon known as accelerated low water corrosion (ALWC) or microbiological induced corrosion (MIC).

Corrosion may be a complex process. Preventing it is not.

Cathodic protection by either ICCP or sacrificial anodes have the ability to effectly protect steelworks against corrosion. Read more about design of corrosion protection for harbours.
