Management of accelerated low water corrosion in steel maritime structures

ALWC is a particularly aggressive and localised form of low water corrosion, which can occur in tidal and brackish waters on steel maritime structures. It could lead to a loss of 33% to 66% of the asset value. This process will rapidly compromise the integrity of affected structures and will lead to significant costs for repair or replacement, in addition to having serious implications for the safe operation of the structure. This publication provides a comprehensive guide to the phenomenon of ALWC and its management, condition appraisal, repair, protection and monitoring. It is aimed at infrastructure owners, operators and their advisors, specialist engineers and asset and maintenance managers in ports, harbours and other marine locations. The guide is based on a detailed review of published literature and infrastructure owner’s procedures, consultation with experts and practitioners from a cross section of fields of expertise and case studies demonstrating good practice.
