Dry dock for building vessels

A dry dock for building vessels including an aft end, a middlebody and a fore end, comprising:

• a main chamber having two ends at, least one of the ends being openable to a water area;
• a separating gate positionable in said main chamber for dividing it into an assembly area and a completion and launching area, a middlebody of a vessel being assembled with a fore end in said assembly area, and the same vessel being completed in and launched from said completion and launching area;
• at least one side chamber extending perpendicular to said main chamber for assembling an aft end of the vessel, the aft end being joined with the middlebody in said completion and launching area;
• an intermediate gate installed between said side and main chambers for separating them from one another so that said side chamber is not flooded during launching of a vessel;
• said separating gate being arranged in said main chamber in such a manner as to form an extension of a wall of said side chamber, which is the nearest wall to said assembly area of said main chamber, so that a first vessel can be launched from said completion and launching area without flooding said assembly area whereby a middlebody and a fore end of a second vessel can be assembled in said assembly area while said completion and launching area is flooded.
