Facing challenges
Port machinery operates continuously in a harsh, highly corrosive environment characterized by high salt mist, high humidity and heat, intense ultraviolet radiation, and frequent mechanical operations. As a result, the steel structures not only endure ongoing marine corrosion but also face challenges such as easy rusting at vulnerable areas like welds and corners, rapid aging of coatings, and limited maintenance windows. Against the backdrop of increasingly stringent environmental regulations, traditional high-VOC anti-corrosion systems are becoming increasingly difficult to sustain, placing port machinery under multiple pressures—balancing protective reliability, service life, and compliance costs.
Solution
Our solution is based on ISO 12944 and industry standards relevant to port machinery. It employs waterborne hyperbranched resins combined with graphene-enhanced technology to develop a systematic, heavy-duty anti-corrosion coating system covering various corrosion categories from C3 to CX. While meeting environmental compliance requirements, this solution provides long-lasting, predictable, and low-maintenance corrosion protection for the steel structures of port machinery.
Project outcomes
After the project’s implementation, the corrosion resistance of port machinery steel structures has significantly improved in high-salt-mist and high-humidity/heat environments. The coating durability and protective performance of critical components have met the design expectations. While complying with environmental regulations, this approach has effectively extended the service life of the equipment, reduced maintenance frequency and repainting requirements, and provided a sustainable corrosion protection solution for ensuring the long-term stable operation of port machinery.
