AI Technical Summary

Technical Problem

In existing technologies, reinforcement is done on the original structure, but the core structure is still the original base, which limits the improvement of structural strength and makes it difficult to further improve structural safety.

Method used

The semi-submersible drilling auxiliary platform adopts a top-and-bottom crane base structure, designed as a hybrid square frame structure, including a base transition section and a lower base section. The crane base and the offshore platform deck are connected by the upper and lower platforms of the transition section, which enhances load transfer and connection strength.

Benefits of technology

This has improved the structural strength of the crane, enabled effective load transfer, reduced construction costs, enhanced the safety and structural stability of the offshore platform, and simplified the construction process.
