On-sea alignment and assembly method for huge blocks of hull

Abstract

The invention provides an on-sea alignment and assembly method for huge blocks of a hull. The method includes the steps of carrying out simulated assembly of the huge blocks; setting assembly locatingreferences on the huge blocks; carrying out floating-state adjustment on each huge block, wherein the draft of each huge block is adjusted to make the drafts of the huge blocks nearly uniform; carrying out on-sea alignment and assembly, wherein with one huge block as a reference block, one huge block is drawn towards the reference block, the huge block and the reference block are located throughlocating assemblies arranged on the huge block and the reference block, the assembly precision is detected through a detector, an underwater welding seam between the huge block and the reference blockis inspected at the same time, and on-water parts of the huge block and the reference block are welded after the huge block and the reference block are located; carrying out docking, wherein the assembled block is pulled into a dock through a pulling device, and after draining, lying on a keel block and locating, underwater remaining parts are assembled and welded. The method solves the problem that due to the large size of existing huge blocks, the huge blocks cannot be assembled in the same factory.

Description

technical field [0001] The invention relates to a sea alignment and closing method for a giant general section of a hull. Background technique [0002] In the prior art, the shipyards are all planning to build the hull. Most of the hull construction process is to carry out the general assembly of the sections to form the general section, and then directly lift the general section or the sections to the dock for closing, and finally complete the hull closing work step by step. , which is characterized in that the closure of subsections or total sections is carried out in dry dock or slipway, which is easy to position, support and weld, and is easy to operate. However, for super-large or special main-scale ships, the hull has many sections and the tonnage of steel processing is large. Due to the limitation of size and scale, it is impossible to complete the construction of the whole ship in a dock of a shipyard, so it needs to be divided into multiple general sections. Constr...
