Water and dock floating closed up technology under half bar ship building berth was built
Technical field:
The present invention relates to hull and close up the operating procedure method of producing whole ship at building berth or the construction of dock branch, particularly at canoe platform constructing part hull, this part hull closes up to big dock and another section body section again, finishes whole assembling and welding.
Background technology:
Hull is built to close up in building berth or dock branch and is produced whole boatman's process, all is that the hull piecemeal is made moulding, on dock, a piece spliced again sectional part hull and simultaneously one section one section close up assembling and be welded into whole hull.Assembling of large-tonnage dock and welding that the large-tonnage ship will be suitable for mutually.Article one, ship is long in the assembling and the welding interval of dock, when having other ships, building on the large-tonnage dock, next bar ship will wait the marquis to last ship build and assemble and test run under behind the water, could begin assembling and weld next bar ship of construction, so the production cycle of ship is long especially.
Summary of the invention:
The present invention solves the assembly construction hull exactly will wait dock, and limited dock makes provides the technical matters that the hull construction cycle is long a kind of short-term to use dock to assemble and be welded into whole hull construction and close up technology.
In order to address the above problem, water and dock floating closed up technology under half bar ship building berth of the present invention was built, it is characterized in that: taked be suitable for one section hull part of one section hull tonnage building berth or H3 building berth construction, water floats to and is suitable for the pier that falls in the big dock of whole piece ship tonnage under one section hull, carry out another segment folding fortification of big section in the depressed place, finish whole assembling and welding at last, whole ship safety is floating undocks.。
The present invention compared with the prior art, can shorten greatly and adapt to the time that the field weld of tonnage dock is built, improved the whole efficiency of building large-tonnage ships at corresponding dock, particularly under the situation of corresponding dock anxiety, plug hole also can build the boats and ships of corresponding tonnage.
Specific embodiment: adopt 200,000 tons of FPSO ships of construction of the present invention, under normal circumstances can only be arranged in the construction of carrying out the whole piece ship in 300,000 tons of docks.But because it is more to need to build the boats and ships that are suitable for 300,000 tons of docks, the plan of 300,000 tons of dock ship closures has been arranged full.Still accept this product in this case, taked to build the long part of half bar ship 120m at improved H3 building berth, after half bar launches a ship, plug hole floats to the pier that falls in 300,000 docks, carries out another segment folding fortification of medium-sized section in the depressed place, finishes whole assembling and welding at last, the time that takies 300,000 docks has only been used one and a half months, just finished the construction that four months whole ships of normal need close up, this ship is floating undocks, and 300,000 docks are followed the normal assembling of following ship of plan and built with welding.
