<p>A module assembly floating dry-dock includes a first pontoon (52), a module turning caisson (64) and a second pontoon (54) positioned adjacent each other, each capable of independent lowering and raising. Hull module subassemblies are lifted into position onto the first pontoon (52) and welded together to construct a hull module laying on its side. The first pontoon (52) can be lowered to float the hull module such that the hull module can straddle the module turning caisson (64). The module turning caisson is then raised to engage a tilting roller conveyor with the hull module, and the first pontoon further lowered, to turn the hull module into an upright position. The hull module can be moved over the roller tracks to an assembly position on the second pontoon (54). The process is then repeated to construct a second hull module and move it into an aligned position adjacent the first hull module so that the two hull modules can be welded together.</p> |
