In order to improve production efficiency and reduce the intensity of painting operation,it is very important for shipyards to choose a suitable coating system for the mechanical space of offshore platforms.Compared with merchant ships,the mechanical space of offshore platforms occupies a larger area,has tight equipment layout,crisscross structure and complex corrosion environment.The selection of coating system here not only needs to consider the basic corrosion protection problem,but also needs to avoid the adverse effects of the cross-work of various types of work on the coating work in the final assembly operation in this area,and surface tolerant self-priming epoxy paint is the most competitive choice.
