Abstract

PURPOSE:To provide a dock which allows simultaneous proceeding of various kinds of work different in construction periods, for building various kinds of ships such as a repair ship, a newly built ship and an offshore structure or the like. CONSTITUTION:A pocket dock 3 wider than a long and narrow dock 1 is connected to one end of the dock 1 having the first opening and closing gate 2 at the other end and plural middle gates 4, 5 at its middle part, and the other end of the dock 3 is provided with the second opening and closing gate 7.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shipbuilding dock, and more particularly to a shipbuilding dock capable of efficiently building new ships, repair ships, marine structures and the like at the same time.

[0002]

2. Description of the Related Art A sill and a construction dock are used for building a ship, and the latter construction dock is used especially for a large ship. Various construction docks such as one having an opening / closing gate only at one end, one having an intermediate gate in the middle, and one having opening / closing gates at both ends have also been proposed and implemented.

When a ship is constructed using such a construction dock, the bow, the cargo hold (the center of the hull),
In general, split construction is performed by dividing into the stern and the stern, but in order to improve the construction efficiency, the stern (engine room), which requires a long construction period, precedes the bow and cargo hold. It is built. On the other hand, the maintenance and inspection work of repair ships has the characteristic that the construction period is relatively short.Furthermore, offshore structures such as offshore work tables used for oil drilling are wide structures and docks of normal width. Since it could not be housed inside and the construction period was long, it was necessary to use a special construction dock.

[0004]

As described above, due to the peculiarities of the conventional ship construction, maintenance and inspection of repair ships, construction period at the time of construction of offshore structures, etc. Was bad.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, in which a first opening / closing gate is provided at one end and a plurality of intermediate portions are provided at an intermediate portion. Provided is a shipbuilding dock in which a pocket dock having a width wider than that of the slender dock is connected to the other end of the slender dock in which the gate is arranged, and a second opening / closing gate is provided at the other end of the pocket dock.

The slender dock is mainly used for maintenance and inspection of repair ships and the cargo hold of new ships is built, and the pocket dock is built for the stern of offshore structures and new ships. This allows it to be used as a multipurpose construction dock.

[0007]

[Embodiment] An embodiment of the ship building dock according to the present invention will be described below with reference to FIGS. 1 and 2. In FIG. 1, reference numeral 1 denotes a slender dock, a first opening / closing gate 2 is provided at one end of the slender dock 1, and a pocket dock 3 wider than the slender dock 1 is connected to the other end.
The intermediate gates 4 and 5 are arranged in the elongated dock 1.

Further, as shown in FIG. 2, an intermediate gate 6 is also arranged at the connecting portion between the elongated dock 1 and the pocket dock 3. And pocket dock 3
A wide second opening / closing gate 7 is arranged at the other end of the. In the ship building dock, when repair ship construction and ship building are performed at the same time, first, the intermediate gates 4 and 5 are arranged to form the repair dock 8 and the cargo hold dock 9, and the cargo hold dock 9 is formed. The cargo hold block M and the stern block A in the pocket dock 3 are pre-built inside, and the first opening / closing gate 2 is opened to dock the repair ship S in the repair dock 8, and after the construction, 1
From the open / close gate 2 of the dock. At this time, the pocket dock 3 and the slender dock 1 are connected to each other to form an integrated dock 10 in which the preceding construction ship is accommodated.

Then, after this pre-built ship opens the second open / close gate 7 and docks, the intermediate gate 5 is opened and the cargo hold block M and the stern block A are integrated into the dock 10 as indicated by arrow B. The new ship N is constructed by connecting and constructing the bow block F while moving to and connecting. On the other hand, when constructing an offshore structure and a new ship, an intermediate gate 6 is provided between the pocket dock 3 and the elongated dock 1 as shown in FIG.
, The offshore structure H is built in the pocket dock 3, the second opening / closing gate 7 is opened, and the ship is docked. Then, at this time, the cargo hold block M is pre-built at the cargo hold construction dock 9, and the stern block A is pre-built at the integrated dock 10, and then the opening gate 5 is opened to open the cargo hold block M at the integrated dock 10.
After being transferred in and connected, the bow block F is connected and constructed.

During this time, a repair ship S having a short construction period is being constructed in the repair dock 8. Then, the first opening / closing gate 2 and the intermediate gate 4 are opened, and the repair ship S and the new ship N are opened.
Will be unwound.

[0011]

As is apparent from the above description, the shipbuilding dock according to the present invention is provided with the first opening / closing gate at one end and at the other end of the elongated dock having a plurality of intermediate gates arranged in the middle. A pocket dock wider than the elongated dock is connected to the pocket dock, and a second opening / closing gate is provided at the other end of the pocket dock.

Therefore, it can be used for construction of new ships, repair ships and offshore structures having different construction periods. That is, since it can be used as a multipurpose construction dock, there is an effect that the dock can be efficiently utilized.
