Corrosion and life cycle management of port structures

Corrosion damages due to splash zone corrosion, concentrated corrosion and salt-induced corrosion have been observed worldwide. Coating is applied to splash zone. Cathodic protection is required for prevention of concentrated corrosion, and both coating and cathodic protection are necessary to prevent salt-induced corrosion. To avoid unexpected large-scale rehabilitation measures as a consequence of negligence of periodic maintenance, systematical planning and budgeting of maintenance activities are necessary. Life cycle management (LCM), and its whole life costing (WLC), will contribute to a realistic approach of maintenance policy.
