Abstract: With the rapid development of offshore oil and gas development, there are more and more underwater production facilities. At the same time, marine fishery fishing methods and fishing equipment are developing rapidly. The impact of fishing activities on these underwater facilities is becoming more and more obvious, and they are damaged by trawling and anchoring. And destruction accidents happen from time to time. In order to ensure the safe production of offshore oil and gas, underwater facilities need to be protected. Fiber-reinforced composite materials have the advantages of light weight, high strength, corrosion resistance, and difficulty in growing marine organisms. Therefore, the application of protective structures for marine oil and gas development underwater facilities has broad application prospects. This article mainly summarizes the application of this type of composite material protection structure, and compares and analyzes it with steel structure and cement briquette protection structure.

Key words: offshore oil and gas, underwater facilities, composite protective structure
