ABSTRACT:
A shipbuilding complex having a dry dock with a dock adjacent area, and a flooding chamber which is adjacent to the head of the dry dock and communicates therewith. An intermediate gate divides the dry dock into a main part which is adjacent to the water area, and a head part which is next to the flooding chamber. The flooding chamber and the head part of the dry dock make up a two-level docking basin. A method for building vessels in this shipbuilding complex is as follows. The aft end and components of the parallel middlebody are assembled in the dock apron area and successively transferred to the upper floor of the junction chamber, whereupon they are floated to and placed on the lower floor of the docking basin to be then transferred to the main part of the dry dock. The latter is used to join together the aft end and the parallel middlebody components, whereupon the preassembled fore end is joined to these to complete the hull. In case gas carriers are assembled in the complex, the tanks are mounted in the middlebody afloat.
