Management of Accelerated Low Water Corrosion in Steel Maritime Structures

Corrosion rates in regions affected by ALWC can be 1mm/side/year or more and design corrosion allowances will, therefore, be exceeded quickly. ALWC can thus lead to an asset value loss of 33% to 66%.

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 report, prepared under contract to CIRIA by Mott MacDonald in partnership with BAC Corrosion Control Ltd, Nuttall John Martin and the Corrosion and Protection Centre at the University of Manchester UK, 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. An Executive Summary gives an overview of the report and answers key questions.

This useful volume 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 documents six case studies within a comprehensive set of appendices.
