Abstract: A dry dock for building and/or dismantling a naval structure includes a substantially horizontal floor located below a predetermined top level, dock side walls extending from the floor to the top level, and a closable access provided in a side wall for moving a naval structure into the dry dock. At least two of the side walls are partly slanted and include a water-impervious layer. The invention also provides a method for constructing the dry dock.

Abstract: A boat cradle system for securely supporting boats, even in hurricane conditions, comprising one or more decks anchored to the ground or to an underlying structure. Moveably mounted on the deck or decks is a series of mobile boat supports that move back and forth between an inoperative position and an operative position.

Abstract: A pre-cast article of manufacture and system, a deck and dock is disclosed utilizing 2 main components, beam(s) and slab(s). Only one component, the cantilever beam, is required for the invention. The preferred embodiment uses a cantilevered Z beam and other embodiments use a drop-cantilever beam and straight-cantilever beam. The cantilever beam may be any shape or size. Optional accessories are also disclosed that may be added such as hand rail(s), boat bumper(s) and water access ladder(s).

Abstract: A method for killing and removing mold and other biological contaminants from structural surfaces. The contaminated surface is enclosed and isolated in a containment area from other noncontaminated surfaces. A biocidal agent is applied to the contaminated surface to kill the contaminant. After the biocidal agent dryes, the contaminant is encapsulated. The contaminant and encapsulant are then removed from the surface by propelling frozen carbon dioxide pellets against the surface at a high velocity. The removed contaminants are collected and disposed of with a high volume air extractor equipped with filters. The containment area may be treated with ultraviolet radiation to kill any remaining contaminants which may be airborne or adhere to the containment area surfaces. A biocidal sealer may be applied to the formerly contaminated surface to prevent regrowth of the contaminant.

Abstract: A method for constructing a large-scale marine structure, which comprises: providing, near a dock (2) of which at least one end faces the waters through a gate (6), a pond (5) having an end thereof facing the waters through another gate (6'); constructing in the dock (2) a plurality of blocks (1A, 1B) for the large-scale marine structure (1); towing out the plurality of blocks (1A, 1B) thus constructed from the dock (2) to the waters, and towing same into the pond (5); tack-welding together the plurality of blocks (1A, 1B) in the floating state in the pond (5); discharging water in the pond (5) to cause the plurality of blocks (1A, 1B) thus tack-welded together to land onto the bottom (5a) of the pond (5); and fully welding together the plurality of blocks (1A, 1B) tack-welded together to construct the large-scale marine structure (1).
