INTRODUCTION AND LITERATURE REVIEW OF CORROSION AND BIOFOULING IN MARINE ENVIRONMENT

Abstract

This study aims to increase the power and the performance of marine structures by protecting them from corrosion and biofouling, which cause reduction of the vessels power. There are many factors in marine environment such as salinity, pH, temperature, and velocity, which cause corrosion. There are three main reasons concerning the study of corrosion. These reasons are safety, economics, and conservation. In addition, there exists the aquatic organism bio-film, which covers the vessels hull. This phenomenon called fouling and it results in increasing hydrodynamic drags, lower the maneuverability of the vessels and increase the fuel consumption. All these factors lead to the deficiency of ships performance. There are many methods that can be used to prevent vessels from the results of fouling and corrosion, among these methods coating i.e. using a highly corrosion resistant material on the ship hull and cathodic method i.e. using zinc for electro mechanic interaction could be effective if implemented properly.
