At the construction site of the Lobito refinery project in Angola, a large storage tank stands in the working area, and an intelligent wall-climbing anti-corrosion robot moves smoothly along the tank wall. Without manual high-altitude climbing, the equipment independently completes the whole process of sandblasting and rust removal, uniform painting, etc., and the whole process is efficient and orderly. The field technicians monitored the operation status of the equipment, debugged the construction parameters, and successfully completed the whole set of practical exercises, which accumulated valuable practical experience for the intelligent construction of overseas energy projects. 

Traditional construction is in trouble 

The Lobito refinery project in Angola is the core benchmark project built by Sinochem Sanjian 's overseas main business. The project is equipped with multiple large storage tanks. The anti-corrosion operation of the tank body is the key process to ensure the long-term safe operation of the equipment. The anti-corrosion construction of the project has the characteristics of large working area, many high-altitude points, high construction standards, strict environmental protection control and so on. The traditional manual operation mode has limited efficiency, which not only greatly increases the labor intensity of construction personnel, but also produces high cost and long construction period. At the same time, the safety hazards of high-altitude operation are difficult to completely avoid, and the overall construction short board is more prominent. 

The introduction of intelligent equipment to enhance efficiency 

In order to solve various construction problems, the project department introduced advanced wall-climbing anti-corrosion robots based on the concept of scientific and technological innovation, and set up a special technical team to deepen the practical application. The equipment is equipped with fully enclosed recycling technology, which can realize the 100 % recovery of sandblasting raw materials, eliminate the problem of sandblasting dust from the source, and meet the green construction standards. During the drilling process, the technical personnel strictly followed the construction specifications, accurately controlled the operating parameters of the equipment, and monitored the core indicators such as sandblasting intensity and painting uniformity in real time. Through repeated debugging and optimization, the construction quality fully conformed to the project design and industry standards.Keywords : overseas engineering, wall climbing robot, intelligent construction

Enhance the core competitiveness of enterprises 

The successful completion of this actual combat exercise fully verified the adaptability and stability of the wall-climbing anti-corrosion robot in large-scale overseas energy projects. This is an important breakthrough in the intelligent construction of Sinochem 's overseas projects, which effectively enriches the overseas construction technology reserves of enterprises. Relying on the application of intelligent equipment, the project completely gets rid of the shackles of traditional construction, effectively improves the efficiency and safety level of anti-corrosion construction of storage tanks, enhances the core competitiveness of overseas engineering construction of enterprises, and provides a mature reference model for the subsequent construction of overseas intelligent sites.Editor / Li Xiaohua
