Methodology and operational model based on biotechnology in corrosion control of vessels and offshore structures

Corrosion in the water environment can be examined from three perspectives, Physical, chemical and biological corrosion. 45% of corrosion occurs by living microorganisms, algae, barnacles’ larvae and other live aquatic animals. Biofouling or accumulation of biological sediments, begins by forming a sticky layer on vessels and offshore structures called biofilms. Economic, social and health problems are the most important adverse effects of corrosion. In this review, using related keywords from scientific databases such as Science Direct, Springer and Google Scholar in the style of "Narrative Review article (s)", "Review of the literature and article (s)" review” the search was done and the content is reviewed. Different chemical and physical methods have been investigated to prevent corrosion. However, based on biological perspective, little attention has been paid to it. The most important methods of bio-corrosion inhibition are nitrate-reducing bacteria, phage display technique, use of bacteriophage and some microorganisms. In this study, using specialized techniques via chemistry, genetic engineering, molecular cellular and biotechnology, biofouling control roadmap that leads to corrosion inhibition has been proposed. By doing this research practically, the corrosion will be controlled at a much lower cost than traditional methods.
