A semi-submersible lifting platform for large floating marine structures and its application method

Abstract

The invention relates to a large-scale floating type ocean-structure semi-submersible lifting platform and an application method thereof and belongs to the field of large-scale floating type ocean-structure maintenance devices and processes. The technical scheme of the semi-submersible lifting platform includes that two ends of a floating box in the length direction are provided with a head floater and a tail floater, transverse moving devices are arranged in the floating box below the head floater and the tail floater, longitudinal moving devices are arranged on the tops of the head floater and the tail floater, a ballast tank and a ballast system are arranged in the floating box, and floater safety decks of the head floater and the tail floater are provided with various functional cabins. The semi-submersible lifting platform can effectively solve the problem about maintenance of the underwater part of the large-scale floating ocean structure with higher length-moulded depth ratio during operation, can realize maintenance, derusting and coating of the large-scale floating type ocean structure on the premise of not docking in, displacing or dismounting, or even not affecting the normal work of the large-scale floating type ocean structure and has the advantages of low construction cost, short period, simple process, wide application range and the like.

Description

technical field [0001] The invention relates to a large-scale floating marine structure semi-submersible lifting platform and an application method thereof, belonging to the field of large-scale floating marine structure maintenance equipment and technology. Background technique [0002] Large-scale floating marine structures such as offshore airports, offshore docks, offshore operating platforms, and large floating bridges are of great significance to the development and utilization of marine resources and the defense of national territorial sea sovereignty. They are currently an important research content in the field of marine engineering in various countries. The above-mentioned large-scale floating marine structures are usually steel plate-girder welded structures, and their local structure is similar to that of ordinary ships. Regular maintenance operations such as repairs, derusting and painting are required for the structures, especially the parts below the waterline....

AI Technical Summary

Problems solved by technology

Due to the large scale, the above-mentioned large floating marine structures are difficult to move, and cannot enter dry docks, floating docks or boarding platforms like conventional ships
