Abstract

The invention relates to the technical field of ship construction, and provides a shipbuilding method that can be quickly carried, which specifically includes the steps of: establishing a three-dimensional coordinate system of a dock that is actually carried; correlating the theoretical three-dimensional coordinate system of the ship with the three-dimensional coordinate system of the carrying dock; Build without allowance; compare and analyze the segmented 3D design model with the measured segmented 3D data, and rectify the problem data; the segmented theoretical 3D coordinate system is associated with the segmented measured 3D coordinate system; the rectified data is imported into the DACS software Carry out simulated loading analysis, deal with the margin of the closing mouth and the dislocation of the structure in advance; carry out the actual loading according to the three-dimensional loading positioning data. The invention achieves the purpose of fast loading and lean shipbuilding by using the three-dimensional coordinate system of the dock. The invention also provides a method for positioning a ship once moving, which uses the three-dimensional coordinate system of the dock to collect relevant data and guides the completion of the positioning of the pier once the ship is moved. The operation is simple and the cycle is short.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a fast-carrying shipbuilding method and a ship-moving positioning method. Background technique [0002] Ocean engineering equipment and high-tech ships are one of the ten key development areas. The shipbuilding industry is the representative of the national strategic equipment manufacturing industry. my country's shipbuilding industry has formed a basic advantage of strong international competitiveness. In 2016, the shipbuilding industry entered a cold winter, and the competition in the shipbuilding market became increasingly fierce. Many private and state-owned shipbuilding enterprises closed down, and the prospect of the shipbuilding industry was worrisome. The shipping market is bleak, and shipowners hold a wait-and-see attitude towards the shipping market and shipbuilding, and implement strategies such as breach of contract, abandonment, and delayed delivery of ships tha...
