Microbially Influenced Corrosion Investigation

Accelerated low water corrosion (ALWC) has been observed on the immersed steel piles in Western Australia. A detailed study was done to establish the mechanism of corrosion and the make-up of the distinctive “orange blooms” that have formed on the steel wharf support piles and wharf sheet piling. In addition to detailed microbial investigations, analysis of the corrosion product was carried out to determine the cause and propagation of ALWC, and proposed solutions nominated.
