Description
Technical field
The present invention relates to Ship Design Technology fields, and in particular to a kind of deck panel stroke of stand alone type storage tank type LNG ship
Divide method.
Background technique
LNG ship refers to the specialized ships that LNG is transported to receiving station from liquefaction plant, at present the storage tank of world's LNG carrier
Type system has stand alone type and two kinds of diaphragm type, and very big, the free-standing storage tank of influence is built in design that the form of storage tank transport LNG
Refer to be not connected with Ship Structure or be not Ship Structure component part cargo containment container, one is placed in each cargo hold
A stand alone type storage tank is not easy to the lifting of LNG storage tank, places for storing LNG.
Summary of the invention
In view of the above-mentioned problems, the invention aims to provide a kind of deck panel division of free-standing storage tank type LNG ship
Method after carrying out segmentation division to deck, closes up mouth using wedge shape, carries out quickly closing up assembly to each segmentation, it is spacious to retain deck
Mouthful, facilitate free-standing LNG storage tank to be hoisted in cargo hold by deck opening, it is ensured that handling, the installation of free-standing LNG storage tank are wanted
It asks.
In order to achieve the above object, this invention takes following technical solutions：
Step 1: dividing the deck region of equal amount according to the cargo hold quantity of ship；
Step 2: each deck region is divided into, deck panel, the segmentation of larboard topside, starboard topside is segmented, tail deck is independently divided
Section, first deck are independent segmented, and the surrounding being respectively segmented closes up seam using wedge shape；
Step 3: deck panel is divided two deck subsections according to the capacity of equipment of shipyard, Ground arrangement；
Step 4: deck subsection carries out total group after the completion of building, deck panel is formed；
Step 5: the segmentation of larboard topside, starboard topside handling subsection to dock to be placed on double bottom block and weld positioning；
Step 6: being hoisted to dock for initial and end deck is independent segmented, it is placed on initial and end transverse bulkhead respectively and welds positioning, with
The topside of the left and right side of a ship is segmented connection；
It is placed Step 7: free-standing LNG storage tank is hoisted in cargo hold on double bottom block by deck opening, the left and right side of a ship
The independent segmented deck opening horizontal plane projection size surrounded in deck of topside segmentation and initial and end, i.e. deck panel horizontal plane are thrown
Shadow size is greater than free-standing LNG storage tank horizontal plane projection size, value 500mm；
Step 8: deck panel is hoisted to deck opening, topside segmentation, the independent segmented conjunction in deck of head and the tail with port and starboard
Hold together, so far entire cargo area segment folding forming.
The present invention has following advantages and effect：Deck subsection forms deck panel on internal field level land, and working procedure mentions
Precedingization, operation internal field, high altitude operation esd ground reduce high altitude operation risk, and entire cargo area deck panel is once hung
Position is transported to, production efficiency is improved；Before deck panel installation, cargo area deck is opened wide completely, is convenient for equipment and materials handling, insulation
It is laid with, LNG storage tank is into cabin location and installation.
Detailed description of the invention
Fig. 1 is flow chart of the invention.
Specific embodiment
The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, and for explaining only the invention, and is not considered as limiting the invention.
In the description of the present invention, unless otherwise specified and limited, it should be noted that term " installation ", " connected ",
" connection " shall be understood in a broad sense, for example, it may be mechanical connection or electrical connection, the connection being also possible to inside two elements can
It, can also be indirectly connected through an intermediary to be to be connected directly.It for the ordinary skill in the art, can basis
Concrete condition understands the concrete meaning of above-mentioned term.
The deck panel division methods of described a kind of free-standing storage tank type LNG ship referring to Fig.1, include the following steps：
Step 1 divides the deck region of equal amount according to the cargo hold quantity of ship；
Each deck region is divided into deck panel by step 2, larboard topside is segmented, starboard topside is segmented, tail deck is independently divided
Section, first deck are independent segmented, and the surrounding being respectively segmented closes up seam using wedge shape；Seam is closed up using wedge shape, deck panel can be convenient
The topside segmentation for importing the left and right side of a ship and the independent segmented deck surrounded in deck of initial and end are open, and realization quickly closes up positioning, together
When the left and right side of a ship topside segmentation and initial and end deck it is independent segmented can effectively support deck be segmented, code at mouth is closed up in reduction
Plate；
Deck panel is divided two subsections according to factors such as the capacity of equipment of shipyard, Ground arrangements by step 3；
Step 4, deck subsection carry out total group after the completion of building, form deck panel, deck subsection（6）（7）It is flat in internal field
Ground forms deck panel, and working procedure is changed in advance, and high altitude operation esd ground reduces high altitude operation risk；Entire cargo area
Handling of deck panel in place, improves production efficiency；Reduce deck in dock and close up seam, improves the complete of insulator laying
Whole degree；
Step 5, first larboard topside segmentation, starboard topside handling subsection to dock, is placed on double bottom block and welds positioning；
Step 6 is hoisted to dock for the deck of initial and end is independent segmented respectively, be placed on initial and end transverse bulkhead respectively weld it is fixed
Position is segmented with the topside of the left and right side of a ship and connects, and the independent segmented topside with the left and right side of a ship in the deck of initial and end, which is segmented, at transverse bulkhead connects
It connects, the bulk strength of carrying stage shell can be improved, reduce the deformation of hull；Exit passageway can be provided simultaneously, facilitates people from two sides
Member's walking and material transport；
Free-standing LNG storage tank is hoisted in cargo hold on double bottom block by deck opening and is placed by step 7, the left and right side of a ship
Topside segmentation and the independent segmented deck opening horizontal plane projection size surrounded in the deck i.e. deck panel horizontal plane of initial and end project
Size is greater than free-standing LNG storage tank horizontal plane projection size, and value 500mm, the topside segmentation of the left and right side of a ship and tail, first deck are only
After vertical segment carrying, free-standing LNG storage tank is hung in cargo hold in which can be convenient by deck opening.
Deck panel is hoisted to deck opening by step 8, and the deck of topside segmentation and initial and end with the left and right side of a ship is independent
Segment folding, so far entire cargo area segment folding forming.
The present invention has following advantages and effect：Deck subsection forms deck panel on internal field level land, and working procedure mentions
Precedingization, operation internal field, high altitude operation esd ground reduce high altitude operation risk, and entire cargo area deck panel is once hung
Position is transported to, production efficiency is improved；Before deck panel installation, cargo area deck is opened wide completely, is convenient for equipment and materials handling, insulation
It is laid with, LNG storage tank is into cabin location and installation.
