Microbially-influenced corrosion of metals at sea is a big safety and financial problem caused by the production of damaging substances such as hydrogen sulphide by sulphate-reducing micro-organisms within biofilms on the surfaces.
There are manifold reasons to avoid corrosion in maritime applications above-sea or sub-sea. Suitable standards to protect parts like boltings and fasteners for many years from corrosion are the cathodic corrosion protection or the use of cost intensive duplex and super duplex steels.
