Semi-submersible seabed processing equipment

Abstract

The invention discloses a semi-submersible seabed processing equipment, which has simple structure, ingenious design and reasonable layout. It uses a stable offshore platform as a basis to design a semi-submersible seabed processing equipment that can move in the X-axis, Y-axis and Z-axis directions. The structure of the movement, the structure can realize the cutting and processing of the seabed rock mass or reef, and at the same time, in order to avoid the problem of affecting the processing due to the shaking of the offshore platform under the action of wind and waves, it also creatively adopts the structure of flexible spindle and floating cutterhead , This cutter head structure can compensate for the shaking of the offshore platform, and the spindle can still provide a stable positive pressure for the cutter head, thereby offsetting the impact of shaking on the cutting work of the cutter head and ensuring that the cutter head will not be damaged. Its appearance has filled the gap in seabed rock mass or reef processing, and has extremely important significance and functions for construction of wharfs, sea reclamation and island construction. Therefore, it can be said that it has many advantages and is especially suitable for this The promotion and application in the field, its market prospect is very broad.

Description

technical field [0001] The invention relates to an auxiliary equipment for an offshore platform, in particular to a semi-submersible seabed processing equipment. Background technique [0002] Currently used jack-up drilling platforms and bottom drilling platforms can only be used on gentle silt seabeds, and cannot operate when the seabeds are uneven rock masses or coral reefs. In the same way, the caisson method is used in repairing docks and occupying islands on islands today, that is, the cement caisson built on land is dragged to the sinking position, and after the seabed drain plug is opened, water is poured to sink to the seabed and then poured into the caisson Put mud and rocks to form a whole, and put a cover plate on it to make a pier or flat ground. When the seabed is uneven, the reef blasting method is required, and then the large reef is removed by a grab-type reef-clearing ship, and the caisson is lowered after basically flattening. Although the above approach ...

AI Technical Summary

Problems solved by technology

Because it is impossible for a general ship not to sway on the sea surface, whether it is rolling or pitching, it may generate tens or hundreds of tons of force on the cutting cutter head, which cannot be tolerated by the cutter head and the main shaft.
