Description

Construction method of ship}

The present invention relates to a ship building method.

The shipbuilding industry, which begins with ordering a ship and goes through design, construction, and delivery, is important in terms of business profitability during the process. One of the factors that determines profitability is the productivity shown in the ship building method, and the shipbuilding industry is making efforts to improve the productivity of ship building. For this reason, the block drying method emerged.

The block building method is a method of first dividing the hull into hundreds of blocks, assembling the individual blocks, and then sequentially mounting the manufactured blocks on the platform to assemble them into a single hull.

Various equipment items are individually installed on blocks that are manufactured separately. Equipment is electronic equipment installed to enable a ship to operate and operate normally, and can be diverse, such as communication devices, ventilation devices, and various power devices.

Meanwhile, large blocks of a certain size or larger are assembled at docks, but there is a risk of work being delayed because it is difficult to build ships at docks, such as when all docks are in use due to large orders. Accordingly, improvement is needed.

The problem that the present invention aims to solve is that even if there is no space in the dock, it is possible to manufacture large blocks such as the bow block that forms the bow and the main block that forms the rest other than the bow, and the dock use time can be reduced to increase the dock turnover rate. The goal is to provide a method of building ships.

The problems of the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

One aspect of the ship building method of the present invention for achieving the above problem is to manufacture each of the main blocks forming the hull excluding the bow part and the bow blocks forming the bow part at an onshore workshop rather than a dock. Steps include loading out the main block to a dock, lifting the bow block with a crane, and assembling the main block and the bow block at the dock to build a ship.

The land-based workshop includes a first land-based workshop provided on a quay wall and a second land-based workshop provided on the quay wall and distinguished from the first land-based workshop, and the step of manufacturing the main block and the player block includes the main block. is dried in the first land-based workshop, the bow block is dried in the second land-based workshop, and the main block and the bow block can be dried at the same time.

The dock is provided as a floating dock, and in the step of lifting the bow block with a crane, the crane is made of a floating crane, and the bow block lifted by the floating crane is connected to the main block on the floating dock. Can be transported to opposite locations.

After the step of building the ship, the step of lowering the floating dock where the ship is located to the floor and launching the ship may be further included.

Specific details of other embodiments are included in the detailed description and drawings.

The ship building method according to the present invention can simultaneously build multiple ships in an onshore workshop regardless of the limited number of docks, thereby preventing work delays due to lack of dock space.

In addition, Figure 4 is a diagram showing the two main blocks of the ship building method according to the first embodiment of the present invention loaded out, and Figure 5 is a diagram showing the front of the ship building method according to the first embodiment of the present invention. This is a drawing showing the block being lifted against the main block.

Referring to Figures 1 to 5, in the ship building method according to an embodiment of the present invention, each of the main block forming the hull excluding the bow part and the bow block forming the bow part are built at an onshore workshop rather than a dock. Step (S110), Loading the main block to the dock (S120), Lifting the bow block with a crane and transporting it to the dock (S130), Building the ship by assembling the main block and bow block at the dock (S140), and a step of launching the ship by lowering the floating dock where the ship is located to the floor (S150).

Prior to the explanation, it should be noted that SHIP1 to SHIP8 shown in the drawing may refer to large blocks forming eight ships, meaning that multiple ships are built simultaneously in one onshore workshop.

First, referring to FIGS. 2 and 3, each of the main block (110M) forming the hull excluding the bow part and the bow block (100F) forming the bow part can be built in an onshore workshop rather than a dock (S110). Here, the land workplace may include a first land workshop (11A) provided on the quay wall and a second land workshop (11B) provided on the quay wall and distinguished from the first land workshop (11A). In addition, one or more Goliath cranes (reference sign, 'GC') may be provided in the onshore workshop, allowing lifting/transportation of blocks such as the main block (110M) and bow block (100F).

In other words, the ship 100 can be manufactured by dividing it into multiple blocks by the block construction method. In this embodiment, the hull is divided into two blocks, such as the main block 110M and the bow block 100F, to provide space. It can be dried in separate, separate land-based workshops.

This is different from the general case where the hull is divided into dozens or hundreds of small blocks, each small block is assembled, and then launched into the dock 12 and assembled into a large block. That is, in this embodiment, rather than being manufactured only in units of small blocks in an onshore workshop, the units of the main block (110M) and the bow block (100F) are built in an onshore workshop, so that the turnover rate of the dock 12 can be improved. , If there is a shortage of docks 12, assembly can be performed at an onshore workshop, thereby preventing work delays due to a shortage of docks.

In addition, the main block (110M) and the player block (100F) of this embodiment are large blocks, which is different from the fact that small blocks are made in a work space such as a PE field. In other words, the main block (110M) and bow block (100F) of this embodiment are manufactured as small blocks in the PE field and then transported to the first land workshop and the second land workshop provided on the quay wall, and are used as large blocks as main blocks ( It is manufactured with a bow block (110M) and a bow block (100F). This is to ensure that the main block (110M) and bow block (100F), which are large blocks, are quickly transported to the floating dock, which will be described later.

In addition, each of the main block (110M) and bow block (100F) of this embodiment is constructed by building the main block (110M) in the first land workshop (11A) and the bow block (100F) in the second land workshop (11B) to improve profitability. 100F), the same work is done in one workshop (the main block (110M) is worked in the space where the main block (110M) is manufactured, and the bow block (100F) is worked in the space where the bow block (100F) is manufactured. work) can be performed to improve work efficiency. In addition, the main block (110M) and bow block (100F) are not manufactured sequentially but individually and simultaneously, preventing work delays that may occur when manufacturing the bow block (100F) after the main block (110M) is manufactured. Thus, work time can be shortened.

For example, the main block 110M of this embodiment may be set to a range that is not limited to obstacles (eg, Goliath Rail Span) of the first onshore work site 11A. However, since interference can be avoided depending on the embodiment, various modifications are possible, such as the obstacle being set to an optimized length considering ease of transportation.

In addition, an engine room may be exemplarily provided in the main block (110M), and of course, equipment such as an engine and equipment such as cables and piping may be provided within the engine room. In addition, various equipment located on the bow block (100F) can be installed.

In this way, the main block (110M) and bow block (100F) individually built in the first land workshop (11A) and the second land workshop (11B) can be transported as follows. That is, once the manufacturing of the main block 110M and the bow block 100F is completed, work can be performed as follows to transport the main block 110M and the bow block 100F.

As shown in FIG. 4 , when manufacturing of the main block 110M is completed, the main block 110M can be loaded onto the dock 12 (S120).

Here, the dock 12 may be a floating dock. As an example, the load-out of the main block 110M may be performed by a crane, but since the number of expensive cranes is limited, it may be performed using a transportation means such as a module car. However, since this is only an example, various modifications are possible, such as two or more main blocks (110M) can be transported to the floating dock at a time using both a crane and a module car.

Referring to FIG. 5, in addition to loading out the main block (110M), the bow block (100F) can be lifted with the crane 13 and transported to the dock 12 (S130). Here, the dock 12 may be a floating dock in which the main block 110M is transported. In other words, the main block (110M) and bow block (100F) can be transported to the dock 12 in the same space.

And the crane 13 that lifts the bow block 100F may be an exemplary floating crane. Here, the floating crane may mean a crane 13 floating on the sea. In other words, the bow block (100F) can be lifted by a floating crane floating on the sea and transported to a location where it is assembled with the main block (110M).

In other words, lifting the bow block (100F) with the crane 13 and transporting it to the dock 12 means that the crane 13 is made of a floating crane, and the bow block 100F lifted by the floating crane is lifted from the main block (100F) on the floating dock. 110M) so that preparations for assembly such as welding can be made.

Next, the ship 100 can be built by assembling the main block 110M and the bow block 100F at the dock 12 (S140). The assembly of the main block 110M and the bow block 100F may be performed by welding. An automatic welding device may be used, as well as manual welding may be performed.

Next, the floating dock where the ship 100 is located can be lowered to the floor to launch the ship 100 (S150).

Here, the floating dock can be moved to an area where floating off is possible, that is, the floating dock can be lowered to the bottom and moved to a position of sufficient depth for the ship 100 on the floating dock to float on the sea.

In this way, the ship building method of this embodiment can simultaneously build multiple large blocks in an onshore workshop regardless of the limited number of docks, thereby preventing work delays due to lack of space.

Although embodiments of the present invention have been described with reference to the above and the attached drawings, those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical idea or essential features. You will understand that it exists. Therefore, the embodiments described above should be understood in all respects as illustrative and not restrictive.
