Corrosion Management of Maritime Infrastructure

Abstract

Maritime infrastructure is at high risk for corrosion-related damage over its service life. These assets are routinely subjected to harsh exposures and heavy usage that can degrade ordinary protective measures for reinforced concrete and steel elements. For owners and operators of ports and other maritime facilities, beginning with a strategic corrosion management plan is a proactive approach for maintenance and replacement needs. A corrosion management plan begins with understanding a few key items. First, identify what infrastructure elements are present and should be inventoried. Second, identify what construction materials and corrosion protection measures are already in place. Third, understand the nature and severity of environmental and usage-related exposures and impact on corrosion. Corrosion management plans have been adopted widely over the years by the oil, gas, and process industries for maintenance of various kinds of equipment, piping, and other needs. However, adoption of these techniques and procedures for civil and maritime infrastructure is still in its early stages. This paper presents the common types of techniques, methods, and documents available for inspecting maritime assets, evaluating exposures, and calculating service life of maritime infrastructure.
