SU640909A1 - Method of expanding multisection floating dock on water - Google Patents

Description

The invention relates to ship repair, in particular to expansion methods, of a multi-section floating dock afloat.

There is a method of increasing the size of ships; when the hull of the vessel is cut in the required plane, the formed parts of the vessel are diluted, a new part is inserted between them and connected to the old ij.

The disadvantage of this method is the technological complexity and the duration of the execution, especially when the width of the ship is increased, due to the fact that the work is performed mainly at the docks, and you have to move large and heavy parts of the vessel and fix their position with high accuracy. .

Closest to the invention is a method for expanding a multi-compartment floating dock afloat by welding the side fittings to the bottom of the case 2j.

The disadvantage of this method is the need to decommission the vessel for the period of welding of bottom fittings, which can take several months.

In order to reduce the duration of the removal of the dock out of operation, during the period of its expansion, the sections are alternately disconnected from the dock, side hopes are welded to each disconnected section, after which the section is again attached to the dock. Then, the on-board structures are moved section by section and secured to the onboard fittings.

The essence of the proposed method is illustrated in the drawings, where in FIG. 1 shows a 4 co {section floating deck}, a plan view; in fig. 2 - floating dock section with one side welded fitting, cross section; in fig. 3 - section of the floating dock after the transfer of the tower, the cross section.

The section pontoon can also be increased from two sides. In this case it is necessary to transfer both towers.

The proposed method for increasing the width of the multi-compartment floating dock is as follows; The end section I, which is fastened with side pins, is detached from the dock, the side fixtures 2 are welded to it, for example, on a slip and connected to the other end sections 1 of the dock.

After that, the second-half-second 3, which has become terminal, is oteoed; by carrying out doko operations w of the withdrawal of ships, the section is made during the period when the ship is in the dock. The entire period of building up the dock sections is thus operated without one section.

After the attachments are welded to all sections of the dock / it is taken out of service, tower 4 by section or parts, overlap {va {oshch1) (and several sections, disconnected from the blemish sections and pontoons S, moved by crane or on Yade 2 and the displaced parts are again connected to adjacent areas and; from Poitonamy 5. The open areas of the pontoons, previously under the tower, are sewn up with steel sheets. If necessary, welding can be welded to each section from both sides. the height of the allotments, which will allow simultaneously with the widening of the dock to increase the height of its towers.

The effect of the proposed method of increasing the width of a multisection floating jsiOKa is due to the fact that during the most time-consuming technological

On the operation-buildup of the pontoons of all the sections of the dock, it is not removed. As a result, the duration of the dock dismantling during the process of increasing its width decreases several times, which saves money and ensures timely docking of the ships assigned to the factory.
