Marine sub-structures are subject to degradation on two main fronts: mechanical (vessel impacts, wear, etc) and corrosion. Corrosion degradation of assets located in and near salt water is often more extensive but gets less attention because corrosion damage is gradual and possibly undetected.

The worldwide cost of corrosion on marine infrastructure is enormous. The landmark 2001 study, sponsored by the US FWHA, estimated the annual cost of corrosion on waterways and ports in the US alone to be $0.3 billion.
