| Steel is one of the most widely used materials in the world of infrastructure for both onshore and offshore platform constructions. However, steel as an offshore structural material is highly susceptible to corrosion, especially seawater corrosion. The method frequently used to protect structural steel from corrosion, both the structure of onshore and offshore construction, is by painting. Other than to beautify, painting also serves to protect the metal surface from corrosion, by forming a layer that can separate and block or isolate between the metal surfaces and environment. The methods of painting on the steel structure for the offshore platform construction is done by several stages, such as primer coat painting, second coat painting, and finish coat painting, thus ensuring the protection of corrosion material well. In the process of painting, temperature and humidity greatly affect the painting’s quality, the higher temperature and the lower humidity then the results will also be better, vice versa. However other factors such as thickness can also affect the quality of the painting, so the painting process must follow the existing procedures such as following the rules on the technical data sheet provided by the product and following the existing standard reference. |
