Embodiment Construction

[0020] See the layout of 2# dock figure 1 , in order to shorten the construction period, it was decided to divide the H1047 ship into two half-ships, A and C, to be built at the same time, so that the space in the dock can be maximized. After the construction, the previous ships are undocked one after another, and then the two and a half ships of H1047 are moved to the pier position where the original ship B is located, the dock door is closed, the positions of the two and a half ships of H1047 are adjusted, and the water is pumped to make it fall to the final position. Welding into a whole ship is a brand-new technology, which is different from foreign and domestic related water docking and closing technologies.

[0021] Because the technical application of the present invention has certain requirements to the design of the hull, therefore, the main dimensions and the volume design of the ship of the present embodiment are:

[0022] The main dimensions of the ship: the overa...

Abstract

The invention discloses a process of afloat ship twin-islet jointing. The process is characterized by comprising the flowing steps of: a, dividing a whole ship into two islets, building the two islets at the same time in a dock; b, performing ballast trimming on adjacent butt joint sections so that the afloat condition and draught of the two butt joint sections are consistent; c, centering, gathering and positioning the two sections; d, draining the dock so that the two islets fall down at specified docking blocks; e, draining a jointing partition; and f, performing assembling and jointing operation so as to complete the overall jointing work of a built object. The process has the advantages that the traditional concept that the construction contract is based on underwater facilities is broken through, and the construction capacity is improved on the basis of the advance of the process technology. The process is adapted to product market, and a large number of investment risks can be avoided, therefore the process is a positive construction method.

Description

technical field [0001] The invention relates to a ship closing process, in particular to a process for building ships with two and a half ships and then closing them up to shorten the construction period. Background technique [0002] Today, when the competition in the world shipbuilding industry is very fierce and the ship price continues to slump, how to improve the quality of shipbuilding, speed up the progress of shipbuilding and reduce the cost of shipbuilding is a problem that every shipyard must face. Shipbuilding is a complex system engineering, which has the characteristics of many types of work, many processes, great difficulty, and large workpieces. In order to obtain the best economic benefits when starting a new ship, it must be combined with the type and characteristics of the product itself. According to the equipment and capacity of the factory, formulate the most reasonable construction plan. The existing construction method prolongs the construction period...
