What is this massive thing on the sea? It is undoubtedly the "heart" of offshore power, the substation! In an extremely corrosive environment, where surfaces are exposed to high salt, humidity, and intense sunlight (C5/CX corrosion level), the design life must be exceptionally long. Thus, the anti-corrosion coating is an essential part; we cannot let the "heart" retire prematurely, causing major accidents or power failure. So, what type of coating should we use? Let’s analyze the coatings used in this application.

First, for the deck, use Graphene Zinc Powder Primer + Epoxy Zinc Silicate Intermediate Coat + Acrylic Polyurethane Topcoat

Second, for the galvanized steel anti-corrosion coating system, use Epoxy Primer, Epoxy Zinc Silicate Intermediate Coat, Polyurethane Topcoat

Third, for hot-dip galvanized stainless steel pipe fittings, handrails, ladders, and cages, use Galvanized Primer + Acrylic Polyurethane Topcoat

Fourth, for high-strength bolts, nuts, and fasteners, use Cold Spray Zinc

Fifth, for the interior walls of the transformer, use Phenolic Epoxy Tank Coating

Sixth, for the exterior walls of the transformer, use Graphene Zinc Powder Primer + Epoxy Zinc Silicate Intermediate Coat, Acrylic Polyurethane Topcoat

The corrosion rate of the galvanized layer is 4.2μm - 8.4μm per year. Severe corrosion affects the mechanical properties of marine platform structural materials, which impacts the safety of the platform's use. Choosing high-quality coatings is critical.
