Detailed Description
The following describes the shape, structure, mutual position and connection relation between the parts, action and working principle of the parts, etc. of the specific embodiments of the present invention, such as the related parts, will be further described in detail by describing examples.
As shown in figure 1, the large marine structure semi-submersible ship floating installation comprises a semi-submersible ship 1, a floating barge 2 and a floating barge 3 No. 2, wherein the floating barge 2 is connected with the semi-submersible ship 1 through crossed strong cables, the two crossed strong cables are respectively connected with the bow and the stern of the floating barge 2 No. 1, the floating barge 3 is also connected with the semi-submersible ship 1 through the strong cables, the two strong cables are respectively connected with the bow and the stern of the floating barge 2 No. 1, and the salvaged sunken ship 4 is fixed between the floating barge 2 No. 1 and the floating barge 3 No. 2 through the strong cables.
In order to prevent the semi-1 semi-submersible from drifting in water at will, the bow of the semi-submersible 1 is connected with an anchor 12 and a No. 6 tug 10, and the stern of the semi-submersible 1 is connected with a No. 5 tug 9; the No. 2 lift-float barge 3 is connected with the No. 7 tug 11 through a powerful cable, the No. 2 lift-float barge 3 is prevented from drifting, the bow of the No. 7 tug 11 is connected with the fixed anchor 13, the bow of the No. 1 lift-float barge 2 is provided with the No. 4 tug 8, one side edge of the No. 2 lift-float barge 3 is propped against the No. 1 tug 5 and the No. 2 tug 6, and the bow of the No. 2 lift-float barge 3 is propped against the No. 3 tug 7 and the No. 4 tug 8. In order to avoid that a fleet of floating barges and sunken ships 4 collides when entering the semi-submersible ship 1, a large anti-collision guide pile 17 is arranged at the bow of the semi-submersible ship 1.
As shown in fig. 2, lifting systems 14 are respectively arranged on the lifting and floating barge 2 and the lifting and floating barge 2, the lifting systems 14 are connected with strong cables, the strong cables are connected with a bolster 16 arranged at the bottom of the sunken ship 4, the bolster 16 is provided with a plurality of channels for lifting, moving and fixing the sunken ship 4, a guide roller 15 is arranged at the contact part of the strong cables and the lifting and floating barge 2, and the guide roller 15 can prevent the strong cables from being worn so as to enable the connection between the systems to be smoother.
When in use, as shown in fig. 1, the marine structure or sunken ship 4 to be loaded is lifted to the sea surface by using two lifting barges provided with the lifting system 14, and the lifting system 14 can adjust the lifting height of the cargo according to actual conditions and keep the posture balance of the structure. The sunken ship 4 is fixed between two floating barges through a strong cable and a bolster 16, and the two floating barges are connected with the semi-submersible ship 1 through the strong cable.
The lifting barge and the marine structure form a large combined fleet by the lifting system 14 and the mooring rope, and synchronously enter the cargo area of the semi-submersible 1 along the large anti-collision guide pile 17 from one side of the semi-submersible 1 according to the method, so that the gap between the fleet and the semi-submersible 1 is effectively controlled, and collision is avoided. When in use, a winch on the semi-submersible vessel 1 is started to pull a powerful cable so that the floating barge gradually approaches the semi-submersible vessel 1, and simultaneously, the riding wheels on the periphery of the floating barge also support the floating barge to push the floating barge to the semi-submersible vessel 1 until the sunken vessel 4 is towed to the semi-submersible vessel 1.
After the sunken ship 4 is towed to the semi-submersible ship 1, the powerful ropes and the hoisting steel wire ropes between the sunken ship 4 and the floating barge are released, and the sunken ship 4 is fixed and towed by the semi-submersible ship 1 or a tug. The method can move ten thousand tons of large marine structures to the semi-submersible vessel 1 to finish loading without depending on the self buoyancy of the marine structures.
While the invention has been described above with reference to the accompanying drawings, it will be apparent that the invention is not limited to the above embodiments, but is capable of being modified or applied directly to other applications without modification, as long as various insubstantial modifications of the method concept and technical solution of the invention are adopted, all within the scope of the invention.
