Embodiment

[0045] The present invention transforms the unmanned cargo barge into a bottom-mounted full-rotation lifting barge. The full-rotation lifting barge mainly includes the main hull of the barge, a full-rotation lifting device, an operation deck, a forecastle and a deckhouse. Functional compartments such as engine room, pump room, auxiliary equipment room and oil water tank are arranged inside. The specific modification methods are as follows, and it should be noted that the sequence of steps included in the following modification methods is not limited, and can be reasonably arranged according to the actual situation.

[0046] 1) Transformation of the main hull of the unmanned barge:

[0047]The original cargo barge of this embodiment has a length of ~171m, a molded width of 32m, and a molded depth of 12m, such as Figure 1a -b shown. Between the head and tail anti-collision bulkheads of the original cargo barge is the warehouse area, with four large cargo holds, and two large h...

Abstract

The invention discloses a modification method based on an unmanned cargo barge and a modified bottom-sitting full-turn lifting barge. The transformation method is as follows: cut off the section of the parallel mid-body cargo hold area of ​​the unmanned cargo barge, and combine the two front and rear sections of the cargo barge after the parallel mid-body section is cut off to form the main hull of the bottom-mounted lifting barge , and take reinforcement measures for the part of the main hull of the bottom-mounted lifting barge; add engine room, pump room, ballast tank, ballast system and oil-water tank below the main deck; set up a main crane at the tail above the main deck, and add a Chimney, forecastle and deckhouse; additional positioning anchor system and outfitting equipment. Transforming the unmanned cargo barge into a bottom-mounted full-slewing crane barge can not only meet the operation requirements of different lifting weights and different lifting heights for offshore floating lifting operations, but also meet the rescue and salvage of ships stranded and wrecked in shallow water reef areas Or the bottom-mounted lifting operation requirements of special engineering projects such as wind power equipment installation in coastal shoal waters, the project is widely applicable.

Description

technical field [0001] The invention relates to a transformation method based on an unmanned cargo barge, in particular to a transformation method for transforming an unmanned cargo barge with a certain parallel midbody length into a bottom-sitting full-turn lifting barge, belonging to the technical field of lifting ships . Background technique [0002] With the rapid development of engineering projects such as offshore oil development, large-scale offshore engineering construction, coastal wind power equipment installation, and shipwreck salvage and rescue, as a commonly used engineering ship, the demand for crane ships is also increasing. In the past, the domestically built full-turn floating cranes did not have the function of sitting on the bottom, so they could not effectively realize the bottom-seat rescue and salvage operations for ships stranded and wrecked in shallow water reef areas or the installation of wind power equipment in coastal shoal waters and other engin...
