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.

Degradation Models and Maintenance Strategies for Reinforced Concrete Structures in Coastal Environments under Climate Change: A Review

“…Authors like Kurth et al [119] affirmed that the adoption of corrosion management techniques and procedures for civil and maritime infrastructure is still in its early stages. The research presented and discussed the common types of techniques, methods, and documents available for inspecting maritime assets, evaluating exposures, and calculating the service life of maritime infrastructures.…”

Cellular Automata Modeling as a Tool in Corrosion Management

“…To effectively manage corrosion, a comprehensive understanding of the corrosion mechanisms associated with the Hydrogen Evolution Reaction (HER), Oxygen Reduction Reaction (ORR), and Oxygen Evolution Reaction (OER) is crucial, along with a deep knowledge of the operating environment and the factors that can either accelerate or mitigate corrosion. Additionally, it is essential to consider the applicable regulations and safety standards from NACE [8] or another standard that can apply regarding corrosion prevention across various industrial sectors, including petrochemicals [9], aeronautics [10], shipbuilding and maritime infrastructure [11][12][13][14], energy [15], mining [16], nuclear waste [17], microbial induced corrosion (MIC) [18], and atmospheric corrosion [19], among others. By incorporating this knowledge, industries can develop robust corrosion management strategies that ensure the safety, longevity, and optimal performance of their assets and infrastructure.…”

Exploration of the effect of Zn-MgO-UPP coating on hardness, corrosion resistance and microstructure properties of mild steel

“…Besides failure and total breakdown consequences, corrosion degradation and loss of mechanical properties have resulted in undesired circumstances such as higher maintenance cost, loss and contamination of products, plant shutdown, expensive overdesign and reduction in production efficiency [9,10]. Even though numerous materials have been employed as surface protectors for mild steel, a number of these materials reportedly failed too early, while other seemingly effective materials were regarded inappropriate and toxic to the environment of application [11,12].…”
