Abstract

PURPOSE:To shorten the occupying period of a specified dock or a building berth by completing a lower section including at least the submerged part of a hull in the first dock or the building berth, and then docking the above lower section into the second dock to complete the remaining section of the hull. CONSTITUTION:In the constructing process of a marine vessel, a hull 3 is first constructed on a block 2 in the first dock. In this case, a rudder 4 and a propeller 5 are mounted on the stern of the hull 3, and a main engine (not shown in figure) is set in an engine room 6, and the hull 3 is completed to a lower section including at least the submerged part of the hull, namely above a draft line 7. Next, the hull 3 is launched to float on the surface of the sea, and pushed out of the first dock 1, and after the hull 3 is docked into the second dock 8, its remaining section is completed on a block 9 to construct a hull 10.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a method of building a ship.

BACKGROUND OF THE INVENTION Conventionally, ships have been generally constructed using either of the following methods (a) and (b).

(a) completing the hull section in one dock or slipway;
After launching, the remaining work including fittings and operation will be completed to complete the ship.

(b) Build the ship by dividing it into front and rear parts using one of the following three methods:

The completion of the stern hull section of a ship and its joining in the dock with the completed bow hull section on another slipway or dock.

The completion of the stern hull section of a ship and its joining in the stern hull construction dock with the completed fore hull section on another slipway or dock.

The stern section of the ship will be completed, moved to another dock, and the bow section will be extended to complete the ship.

Problems to be Solved by the Invention However, the above conventional methods have the following problems.

In the method of completing the hull portion at one dock or berth as in (a) above, there is a problem that the period of occupation of a particular dock or berth is too long.

If a ship is constructed by dividing into front and rear sections as in (b) above, the front and rear sections will be submerged in seawater, and the vibrator at the section will need to be cured to prevent water from entering. Additionally, parts of the hull structure that have been submerged in seawater must be cleaned of mud.

Furthermore, even though multiple docks or berths are used, the part of the bottom of the ship that corresponds to the board is the same, and in order to paint the part of the bottom that corresponds to the board, it is necessary to redo the dock once the hull is integrated. I have to let it happen.

An object of the present invention is to provide a method of building a ship that solves all of the above problems.

Means for Solving the Problems A method of building a ship according to the present invention includes mounting a rudder and a propeller on the stern portion of the ship at a first dock or a slipway, and completing the lower portion of the ship including at least the submerged portion; The method is characterized in that the hull is launched in the same state and docked at a second dock, and the remaining portion of the hull is completed at the second dock.

Dock, like the first dock, is equipped with equipment suitable for mounting rudders, propellers, etc. on the ship's hull, and the construction period at a dock with such special equipment is as short as possible. It is preferable to shorten it and increase the rotation of the dock. The same applies to the boat platform. In the method of the present invention, the ship is launched at a first dock or a slipway with the rudder and propeller mounted on the stern part and with only the lower part of the ship, including at least the submerged part, completed. Since the ship is docked at the second dock, the period of occupancy of the first dock or berth is shortened, and the rotation rate is increased.

In addition, when launching a hull built at the first dock or slipway, at least the lower part of the hull, including the submerged part, is completed, so there is no need for the split points to be submerged in seawater as in the past. .

Furthermore, since the lower part of the hull is completed at the first dock or slipway and then transferred to the second dock, the bottom part that was in contact with the board at the first dock or slipway is moved to the second dock.
In the dock, this part can be easily painted without touching the board.

Embodiment FIGS. 1 to 3 show a method of building a ship according to the present invention.
Examples are shown in the order of steps.

Hereinafter, the ship construction process will be explained in order with reference to these drawings.

First, at the first dock (1), the hull (3) is built on a board (2) (see Figure 1).

In this first dock (1), a rudder (4) and a propeller (5) are mounted on the stern portion of the hull (3), and a main engine (as shown) is mounted in the engine room (6). Further, the hull (3) to be constructed at the first dock (1) has at least the lower part including the submerged part of the hull completed. In other words, it has been completed above the water line (7) in this state.

Next, this hull (3) is launched and floated to the sea surface (second
(see figure) and discharged from the first dock (1).

The first dock (1) is equipped with equipment suitable for mounting the rudder and propeller on the hull, and the main engine is also constructed to be conveniently transported to the dock (1). .

Therefore, it is preferable to shorten the construction period of a dock with such special equipment as much as possible to increase the turnover of the dock. In this method, a rudder (4) and a propeller (5) are attached to the stern part of the hull (3) at the first dock (1).
) and the main engine, and the hull (3) is launched and docked with only the lower part of the hull, including at least the submerged part, completed, so the first dock (1
) can be used to increase rotation by shortening the period of occupation.

In particular, if the lower part of the hull (3) is completed when the rudder (4), propeller (5), and main engine are installed, the period of occupation of the dock (1) can be minimized.
You can increase the rotation to the maximum.

Furthermore, when launching the hull (3) built at the first dock (1), at least the lower part of the hull below the water line (7) including the submerged part is completed, so There is no possibility that the divided part will be submerged in seawater, and therefore the divided part will not get dirty or water will seep through the divided part.

Next, the hull (3) that was docked from the first dock (1) is docked at the second dock (8), the remaining parts are completed on the board (9), and the hull (10 ) (see Figure 3). At this time, the board (
It is easy to prevent the bottom part of the ship that was in contact with the board (9) from touching the board (9), and if you do this, the
The bottom of the ship, which could not be painted because it was in contact with the board (2) on the dock (1), can be easily painted.

In this way, the work on the bottom of the ship at the second dock (8) is limited to painting the parts that could not be painted at the first dock (1) because they were in contact with the board (2).

Effects of the Invention According to the ship construction method of the present invention, as described above, the period of occupation of a particular dock or berth can be shortened, and the dividing point can be prevented from being submerged in seawater as in the past. Moreover, the part of the bottom of the ship that corresponds to the board can be easily painted.
