Marine Corrosion

Marine and Offshore Corrosion describes the principles of effective corrosion control treatments in marine environments, with emphasis on economic solutions to corrosion. The book explains chemical or electrochemical reaction of an alloy with its environment leading to corrosion, and mechanical loss of the metal by erosion, abrasion, or wear resulting also in corrosion. A main consideration of erosion control that the engineer should look into is the economic side. Other considerations that he should investigate are the strength of a structure, time for construction, availability of materials, and costs. The book also discusses the marine environment consisting of sea water, temperature fluctuations, dissolved gases, hydrogen sulphide, ammonia, carbon dioxide, electrical conductivity, fouling. The text describes the selection of materials to be used in marine environments, surface preparation of steel before painting, the type of paint, and metallic coatings. Some of the factors in selecting coating systems are: cost and estimated life before the first scheduled maintenance, adhesion properties, moisture tolerance, elasticity, chemical resistance, impact resistance, bacterial resistance. The factors affecting maintenance include environmental conditions, quality of initial protection applied, type of structure, as well as the design and purpose of the structure. The book has been prepared for engineers and designers who are not corrosion specialists but have to deal with marine corrosion problems as part of their day-to-day professional activities. The text will also turn out to be useful for engineers with general interest in structure, building, or machinery maintenance specially those located near coastal areas.

Corrosion and Corrosion Protection of Wind Power Structures in Marine Environments: Volume 2: Corrosion Protection Measures offers the first comprehensive review on corrosion and corrosion protection of offshore wind power structures. The book extensively discusses corrosion phenomena and corrosion types in different marine corrosion zones, including the modeling of corrosion processes and interactions between corrosion and structural stability. The book addresses important design issues, namely materials selection relevant to their performance in marine environments, corrosion allowance, and constructive design. Active and passive corrosion protection measures are emphasized, with special sections on cathodic corrosion protection and the use of protective coatings. Seawater related issues associated with cathodic protection, such as calcareous deposit formation, hydrogen formation, and fouling, are discussed. With respect to protective coatings, the book considers, for the first time, complete loading scenarios, including corrosive loads, mechanical loads, and special loads, and covers a wide range of coating materials. Problems associated with fouling and bacterial-induced corrosion are extensively reviewed. The book closes with a chapter on recent developments in maintenance strategies, inspection techniques, and repair technologies. The book will be of special interest to materials scientists, materials developers, corrosion engineers, maintenance engineers, civil engineers, steel work designers, mechanical engineers, marine engineers, chemists, and coating specialists. Offshore wind power is an emerging renewable technology and a key factor for a cleaner environment. Offshore wind power structures are situated in a demanding and challenging marine environment. The structures are loaded in a complex way, including mechanical loads and corrosive loads. Corrosion is one of the major limiting factors to the reliability and performance of the technology. Maintenance and repair of corrosion protection systems are particularly laborious and costly. Explores the literature between 1950 and 2020 and contains over 2000 references Offers the most complete monograph on the issue Covers all aspects of corrosion protection in detail, including coatings, cathodic protection, corrosion allowance, constructive design, as well as maintenance and repair Delivers the most complete review on corrosion of metals in marine/offshore environments Focuses on all aspects of offshore wind power structures, namely foundations, towers, internal sections, connection flanges, and transformation platforms

Cathodic protection (CP) mitigates the high cost of steel and other alloys corroded in seawater and seabed sediments. Marine Corrosion and Cathodic Protection is a comprehensive guide to corrosion issues and presents methodologies to tackle common offshore code-based CP designs. Advanced theory is developed for non-routine CP applications, with and without subsea coating systems. The interactions between CP and the fatigue and hydrogen embrittlement characteristics of alloys are explained. Sacrificial (or galvanic) anodes and impressed current systems are examined, followed by descriptions of successful and unsuccessful applications on petroleum installations, harbours, jetties, pipelines, windfarm foundations, ships and floating production storage and offloading vessels FPSOs. Retrofit CP systems for the life extension of assets, together with methods for applying CP internally in both static and flowing systems are evaluated. A critical review of the role of physical and computational modelling in CP design and evaluation addresses the more geometrically complex applications. Techniques for, and limitation of, CP surveying, inspection and monitoring are explained in the context of system management. This text is ideal for engineers, designers, manufacturers, equipment suppliers and operators of offshore CP systems.

The diversity of subjects involved in marine corrosion and fouling processes are evident in the approaches and techniques described in this book. An improvized understanding of biologically influenced corrosion and fouling processes is essential to the development of better corrosion protection systems, and this book shows new perspectives in our appreciation of these subjects. Equally, powerful microscope imaging, surface spectroscopy and electrochemical techniques have become available and are providing new information on metal surfaces experiencing fouling or microbial corrosion. Examples include confocal laser microscopy, scanning probe microscopy, Fourier Transform infrared spectroscopy, scanning electrochemical microscopy and scanning (or vibrating) reference electrode techniques. Advances in knowledge of biocorrosion processes have enabled improvements in corrosion monitoring and protection strategies. Examples include metal or polymer coatings and the use of corrosion inhibitors and biocides. This book aims to provide a contribution to existing literature on biocorrosion in the marine environment.
