A module for making a modular ferry and/or a floating bridge including a floatation tank, where the floatation tank is made in the form of two floatation half-tanks hinged together around a hinged line between an opening position in which the two half-tanks are substantially aligned and form the floatation tank, and a closing position in which a half-tank is folded back upon the other half-tank such as a lid thus forming a container box able to enclose all or part of the elements for making the ferry or floating bridge.

A vessel hull having a pair of vents formed in the chine on each side for allowing air to be introduced to the bottom and a pair of downwardly extending fins formed longitudinally along the chine adjacent to each vent. Each vent can be formed by a recess in the chine dividing the chine into a forward portion and an aft portion. Each fin is preferably formed longitudinally along the aft portion of the chine and extends below the waterline. The fins counterbalance the removal of a portion of the chine to vent the bottom and increase stability during turns. The hull preferably also includes a pair of chine extensions projecting aft of the transom on each side for reducing or eliminating side-to-side oscillation of the stern when the hull is propelled through the water at slow speeds.

Accordingly, the preferred embodiment of the present invention includes ft and second pontoons; a plurality of removable connector modules located in pockets on each end of the pontoons for absorbing impacts and for locking together joined pontoons; a plurality of retractable, resilient alignment pins located in the ends of the pontoons for initial alignment of the pontoons; and a winch operated bridal line attached to the alignment pins, via guide bores, for drawing together the pontoons in a joined fashion. Each connector module includes, on one end, a compressible locking pin that may be slidably located in the extended position (for joining and locking together with another pontoon) or in the retracted position (for storage). The other end of the connector module includes a receiver bore for receiving the locking pin of a mating pontoon. The removable connector modules may be installed in a "regular" fashion, with the locking pin adjacent the deck of the pontoon or in the "inverted" fashion, with the locking pin adjacent the sea surface. Once joined together, two pontoons are locked together via the locking pins. The locking pins also may compress to absorb impacts from a mating pontoons due to misalignment of the pontoons in rough, undulating seas. The alignment pins are resilient to initially guide and absorb forces between bumping pontoons as the pontoons are drawn together. Several pontoons may be joined, in succession, to form an array of pontoons of desired length by repositioning the bridal line to attach to the next pontoon to be joined. Pontoons may also be joined, for example, at the side to form other combinations of structures.

The fixtures in which curved and reinforced flat plates are held while being welded, cleaned, coated and cured include fixedly mounted exterior towers and interior towers removably mounted on rollable bogies (i.e., rail cars or carriages) for ease of transport through a succession of work stations. Subcomponents fabricated on respective bogies are weldingly joined to form module subassemblies after coupling and maneuvering the respective bogies to align the subcomponents (i.e., units). A transverse bulkhead is supported on fluid cushion pallets beside the bogie-supporting rails, so that the transverse bulkhead can be positioned for welding of each subassembly thereto, to provide each respective double-walled vessel hull midbody module.

A variable capacity floating articulated barge assembly including two barges which are pivotally connected at their mating ends. An elongated structure to be launched is jacked to initiate it sliding along skidways on each barge toward one end region where a pivotal support member finally supports this structure prior to it being launched from this barge assembly. During launching the barges and the support member of this assembly pivot with respect to each other depending upon the degree and location of the load.

Rectangular base mounting-platform structures for removable combat-equipment, for example, guns and other support units like radar which are mounted on rectangular openings on a ship-deck, are provided with interchangeability. In order to achieve interchangeability of units which have mounting-platform structures of unequal size, the platform rectangular dimensions as well as the dimensions of the corresponding rectangular openings are so designed that the base length of the smallest unit is made equal to the width of the next bigger rectangle and so forth; in order to mount the smallest rectangular base on the immediate next larger rectangular opening, the length of the smallest rectangular base is aligned with the width of the larger opening; mounting is so done as to leave an open space towards only one side, leaving only one longer side of the smallest rectangular base unsupported within the area of the mounting opening. The unsupported side is supported by a beam running under the mounting opening, which beam transfers the load to other structure which reinforces the rectangular opening. An area of the rectangular opening which is thus left uncovered is covered by a suitable covering member. The mounting of the rectangular base structure, and the covering member, as well as the ends of the beam, are provided with sealing members to render the platform-structure impervious. Three consecutive rectangular sizes are preferred wherein the width of a rectangle is the same as the length of the immediate smaller rectangle.

A hinged floating box caisson structure includes a central caisson, a pair of lateral caissons and a pair of end ballasts, these elements are adapted, when in a transport position, to be folded on one another. A system for straightening the end ballasts and for unfolding the lateral caissons is arranged to produce simultaneously a 180-degree rotation of the lateral caissons and the straightening of the end ballasts. One actuator is provided for controlling these simultaneous movements.

Building equipment for a hull comprising a hull joining stage having a bottom surface level flush with the ground level of the site; a stern building stage having a bottom surface level flush with that of the hull joining stage, provided at a longitudinal end of the hull joining stage so as to be adjacent thereto through a gate; a bow and parallel body building stage having a bottom surface level flush with that of the hull joining stage, provided at the other longitudinal end of the hull joining stage so as to be adjacent thereto through another gate; a pond having a bottom surface lower than that of the hull joining stage, provided longitudinally in parallel with and adjacent to the hull joining stage on the water side, a longitudinal end of the pond being open to a body of water through still another gate; cranes travelling linearly along the hull joining stage, the stern building stage and the bow and parallel body building stage; and partition walls higher than the ground level and the level of the body of water, comprehensively enclosing the hull joining stage and the pond in water-tight manner in conjunction with the three gates. The building equipment for a hull covers also a combination comprising the bow and parallel body building stage divided into two parts, namely: a bow building stage and a parallel body building stage.

A watertight floating box, for use in working on floating bodies such as ship sections or the like to be assembled, disassembled, repaired, or maintained while afloat comprises caisson means arranged to embrace, in watertight manner, the underwater portions of the floating body and arranged to be pumped free of water to provide a dry working space along the underwater portions of the floating body. The caisson means includes a bottom structure to extend horizontally and transversely across the bottom of the floating body and sidewall structures extending substantially vertically upwardly in facing relation with the sidewalls of the body. The sidewall structures are arranged for adjustment relative to each other transversely of the floating body in accordance with the beam or width of the floating body.
