This report basically discusses the research done and basic understanding of the chosen topic, which is Study on Epoxy Mastic Coating of Submerge Structure (Jackets, Buoy, and Ballast Tank). The objective of the project is to study the performance the chosen coating with different surface roughness and the corrosion properties of the sample. This study also includes the effect of barnacle to the coating system especially in the marine environment. Submerge structure e.g. jackets of offshore platform, buoy, and also ballast tank wiii fail when painting or coating failure. When coating fail, seawater corrosion, oxygen corrosion and microbiologically induced corrosion (MIC) wiii contribute and lead to the mass failure. Corrosion is the main threat in the oil and gas industries and miiiions of dollar has been expense by oil and gas company to study the corrosion behavior so that they can encounter corrosion and prevent it before corrosion attacks the piping, equipments and other steels attached. In order to achieve optimum perfurmance of the coating system, the right choosing of coating specification, surface preparation and application technique is very important. Coating can fail if inappropriate surface preparation is chosen since this criteria are important to the adhesion of the coating itself and the respective substrate surface. At the end of the project, we wiii know the result expected on epoxy coating adhesion, corrosion properties and also it barnacle effects
