Description

Accurate troubleshooting and early safety troubleshooting systems for marine equipment can be used to schedule maintenance, extend service life, and ensure personal safety.
Large infrastructures and special equipment at sea are usually made of metal materials or reinforced concrete, and the safety of the marine engineering facilities is seriously threatened by the occurrence of corrosion. At present, the most common method for monitoring the corrosion state is to make an electrochemical sample of the material used at each important part of the machine equipment and connect the electrochemical sample with an electrochemical workstation to measure transient corrosion kinetic parameters such as open-circuit potential, corrosion current and electrochemical impedance spectrum. If the current measurement is within the range, the condition of the marine equipment component suffering from corrosion damage is good. If the current value is out of range, corrosion attack is severe and an alarm is sent. However, the health condition of the complex equipment cannot be reliably judged according to the analysis of single measurement, and the instability, weakness, randomness and complexity of the fault signal of the single sensor make the fault signal at the initial stage of the corrosion accident easily submerged in noise, so that the monitoring significance is lost.
The corrosion diagnosis is not a one-to-one simple solving process, and the corrosion diagnosis is comprehensively judged by comprehensively using the modern multidisciplinary fusion technology. The occurrence of corrosion is strongly related to the temperature, humidity and chloride ions in the offshore atmospheric environment, and the concentration of chloride ions is strongly related to the wind speed and the wind direction. Meanwhile, the influence of corrosion at the monitored part can cause a certain quality loss and corrosion product adhesion, and the corrosion degree is potentially related to the vibration acceleration and the vibration amplitude of the part. Therefore, a state monitoring device based on multi-sensor equipment fusion is needed to continuously monitor the corrosion safety state of the offshore equipment.
