Combined semi-submersible transport ship and working method thereof

Abstract

The invention relates to a novel semi-submersible transport ship, in particular to a combined semi-submersible transport ship and a working method thereof and belongs to the technical field of semi-submersible transport ships. The combined semi-submersible transport ship is characterized by comprising two end ship bodies and a middle cargo carrying floating plate. The two end ship bodies are connected to the two ends of the middle cargo carrying floating plate and can be detached. The two end ship bodies can voyage independently and have the downward diving and upward floating capability. The middle cargo carrying floating plate has the independent downward diving work capability and can be remotely controlled by the end ship bodies to conduct downward diving work. The novel semi-submersible transport ship solves the problem that a traditional semi-submersible transport ship is insufficient in stability and reserve buoyancy in the downward diving process and solves the problem that in the downward diving process, the ship shakes violently and errors are prone to generation by operation personnel.

Description

technical field [0001] The invention relates to a novel semi-submersible transport ship, in particular to a combined semi-submersible transport ship and a working method thereof, belonging to the technical field of semi-submersible transport ships. Background technique [0002] A semi-submersible transport ship is a special engineering ship with a huge cargo deck area and partial submersion capability, which can transport and load super-long, over-weight, and inseparable super-large special cargo, especially offshore engineering platforms. Most of its hull can be submerged underwater during loading and unloading operations, while it is in a normal draft state during navigation. The semi-submersible ship uses its own ballast system to submerge the cargo deck of the hull into the water. After the load is dragged to the top of the deck, the hull is floated through the ballast system, and the load is lifted out of the water and secured. ;When the load arrives at the destination...

AI Technical Summary

Problems solved by technology

[0012] The current semi-submersible transport ships generally have problems of insufficient buoyancy and stability during the dive process, and the existing countermeasures will bring various unfavorable factors; at the same time, the current semi-submersible transport ships are often based on specific cargo Carrying out customization, the flexibility of picking up goods is low, and the economy is poor, which leads to high freight costs, which to some extent restricts the progress of ocean development.
