Halcrow sheds light on ALWC problem.
(From Gulf Construction)
The hot climatic conditions prevalent in the Gulf promote rapid biological activity and are conducive to accelerated low water corrosion (ALWC). Dr GAVIN CHADBOURN and DAVID POCOCK of Halcrow International suggest approaches for repair and remediation of ALWC-damaged structures
Microbial-induced corrosion of marine structures predominately affects steel structures, whereby multi-species colonies of bacteria present in seawater metabolise sulphates under anaerobic conditions generate hydrogen sulphide, a corrosive compound that reacts with steel to form iron sulphide. The situation is exacerbated as iron sulphide is strongly ...
