Business Areas

• Hull Corrosion Prevention Solution (ICCP): We design, manufacture, and supply ICCP systems to prevent electrochemical corrosion of ship hulls caused by continuous contact with seawater. This system operates on the principle of continuously flowing a small direct current through the hull to control the potential difference that causes corrosion.
• Marine Growth Preventing System (MGPS): We provide a Marine Growth Preventing System that prevents marine microorganism attachment in ship's internal piping. This contributes to increasing ship operational efficiency and reducing maintenance costs.
• Ship Component Manufacturing and Engineering Services: We are a domestic specialist company that manufactures hull cathodic protection systems and internal piping anti-fouling systems, supplying equipment to domestic and international shipyards, shipowners, and agents, and providing related service engineering.

Products

• ICCP (Impressed Current Cathodic Protection): This is an external power source cathodic protection device that fundamentally prevents hull corrosion by applying impressed current. We provide customized solutions not only for newly built ships but also for those already in operation.
• MGPS (Marine Growth Preventing System): This system prevents marine microorganism attachment in ship's internal piping through micro-currents. It is an essential product for efficient ship operation and extended equipment lifespan.
• SED (Shaft Earthing Device): This equipment is for preventing electrolytic corrosion of ship shafts and includes core components of ships such as shaft grounding devices.

Special Notes

• Technology-driven Corrosion and Biofouling Solutions: We possess specialized technology in developing and supplying electrochemical cathodic protection solutions that address corrosion and marine biofouling issues in ships and marine structures. Based on our unique core technologies, we secure a differentiated competitive advantage in related fields.
