Abstract

The present invention discloses a paint management system. The paint management system is a paint management system for an offshore structure to which an ICCP (Integrated Current-Caused Poison Control) system is applied, which prevents corrosion of the hull by applying current to an anode member connected to the hull and measuring the potential of the hull through a reference electrode to maintain a potential difference between the anode member and the hull. The system may include a calculation unit that calculates the current paint condition of the hull using a measurement value measured by the ICCP system.

Description

Marine Structure Coating Management System The present invention relates to a marine structure paint management system capable of monitoring the paint condition of a hull and predicting the paint life of a hull in a marine structure to which an ICCP (Integrated Current Poison Control) method is applied. The hull, which is the outer plating of marine structures such as ships and offshore plants, is not only painted to prevent corrosion caused by seawater but is also equipped with a cathodic protection system. Cathodic protection is a method that prevents corrosion by lowering the potential of the steel used for the hull, and Impressed Current Cathodic Protection (ICCP) is an example of cathodic protection. The current application method utilizes a technique of lowering the potential by directly applying an electric current to the hull, and a large surface area can be protected from corrosion by discharging the current through the anode. The amount of current discharged through the anode is controlled according to the potential value set at the reference electrode. When the hull is well-painted, the amount of current discharged through the anode is small, but as time passes and the paint deteriorates or is damaged, the amount of current discharged through the anode increases. Since there is a limit to the amount of current that an anode can discharge, paint maintenance is required to prevent continuous hull corrosion when paint deterioration and damage become severe. Therefore, it is necessary to monitor the condition of the hull paint to determine the maintenance schedule, while also predicting the paint's lifespan based on its current state.
