Underwater robot corrosion monitoring system and what are the imaging detection technology characteristic

Corrosion monitoring system for the detection of the main advantages: (1) has high detection accuracy and test results is not affected by the operator; (2) can be used in detection of complex geometry (elbow joint, T -, Y - joint, etc.), at the same time for the geometry, the FSM technology can greatly reduce the testing time. To a point, if UT need 1 ~ 2 hours, using FSM is only 3 ~ 4 minutes; (3) because of the remote detection ability, reduce or eliminate the cost of building scaffold; (4) for general corrosion, its sensitivity is higher than 0.5% of the remaining wall thickness, that is, the actual sensitivity increased with the increase of corrosion, the sensitivity is 1 o UT times, at the same time, good repeatability; (5) do not need to remove coatings or thermal insulation layer, thus greatly save the money and time. 3.3 underwater robot and imaging techniques to monitor underwater robot probes and imaging detection is mainly suitable for water depth is deep (more than 50 m) state of corrosion detection. Using underwater robot compressive properties of the deep and clear level of imaging intuitive photos and videos, observation of underwater steel structure corrosion condition. Potential probe was used to measure of cathodic protection potential of underwater steel structure, in a timely manner to understand the status of the corrosion, the corresponding measures. At present domestic imaging detection technology of underwater robot probes and use case is not much, cnooc shenzhen branch in the south China sea corrosion status of offshore platform jacket used in the detection.

Cathodic protection technology as the main control platform underwater steel structure corrosion measures has been extensively applied in cathodic protection monitoring system is an important component of the cathodic protection system. It through continuous automatic measurement platform jacket tour different parts of the cathodic protection system main operation parameters, and timely information platform of the cathodic protection of underwater steel structure, save the test fee, to ensure long-term safe operation of the platform structure is of great importance, and cathodic protection system for the new platform of economic, reliable, and provide a scientific basis for the design of the reasonable, safe.
