[0002] Offshore oil and gas drilling and production equipment requires higher technological content and innovative ideas, among which offshore oil and gas drilling platforms are one of the key equipment for marine development.

[0003] The Chinese utility model patent currently announced as: CN202926224U discloses a drilling platform guardrail, which includes a guardrail module. The guardrail module is composed of a combination of steel pipes as crossbars and columns. The two guardrail modules are combined into one by connecting the module connectors at the ends of their crossbars; the cross-section of the module connector is a stepped pipe fitting with a large middle and small ends, the wall thickness of the two ends is equal to the wall thickness of the steel pipe in the guardrail module, the outer diameter of the two ends is consistent with the inner diameter of the steel pipe in the guardrail module, and the outer diameter of the middle part is equal to the outer diameter of the steel pipe in the guardrail module. The advantage of this utility model is that the modules are combined into a guardrail to form a whole, which overcomes the disadvantages of the existing guardrail modules being independent of each other and avoids the waste of steel caused by relatively repeated column parts, which not only improves safety and reliability, but also reduces the total cost of the guardrail.

[0004] Although this patent has the function of protecting offshore oil platforms, it is not clear how the columns are connected to the platform, and it is also unclear what material the guardrails are made of, so it needs to be improved. Utility Model Content
