Definitions

  • the present invention relates generally to foldable watercraft and in particular, to craft capable of transporting standard shipping containers and being folded into the dimensions of the same and in so doing reducing its hull area by no less than 50%.
  • Shipping containers are the predominant form of transporting containerized goods or produce throughout the world, particularly by sea.
  • the international standardization of shipping container dimensions permits the use of automated container handling systems and the compatibility of different transportation means to move a given container via air, land or sea.
  • the majority of cargo handling equipment is specifically configured to handle containers of internationally agreed dimensions such as those specified in the Australian and New Zealand Shipping container standards AS/NZS 3711.1;1993, the International (ISO 1496) or British (BS 3951) standards.
  • the dimensional tolerances permitted under such standards are extremely small (between, 1.5-10 mm maximum).
  • This enables the use of standardized lift and securement fittings to be accurately placed at defined positions about the container periphery.
  • Such standardized container handling fittings permit individual containers to be secured to each other and/or to the deck of a ship, truck, or plane by correspondingly dimensioned standard container handling means.
  • twist locks as defined by the ISO 1161/BS 3951 and AUS/NZS 3711.3:1993 standards
  • Such a craft would require the structural integrity and load carrying capacity necessary to accommodate a standard shipping container and its load; (which may be up to approximately 24 tonnes including the weight of a 3 tonne 6 meter container or a 30 tonne 12 metre container) in a secure and seaworthy manner.
  • a standard shipping container and its load which may be up to approximately 24 tonnes including the weight of a 3 tonne 6 meter container or a 30 tonne 12 metre container
  • Such requirements would typically require a craft of a significant size and strength. Consequently, storage of such a craft may be problematic on a vessel configured to store objects the size of shipping containers. Further storage difficulties may arise from the irregular shape of such a landing craft/barge.
  • a watercraft capable of being easily handled by standard shipping containers handling means when being deployed and/or stored whilst also being capable of transporting a standard shipping container in use.
  • said craft itself should be capable of being folded into the dimensions of a standard shipping container.
  • a water craft with a operational deck area capable of carrying a shipping container, said craft being collapsible into a volume that is substantially coterminous with a standard shipping container and in so doing reduces it's hull area by no less than 50%.
  • the whole collapsed craft may be moved as a unit using standard shipping container handling systems.
  • the craft obviates the need for specialized custom storage positions and fittings for the erected craft and may instead be readily stored in any conventional position suitable for other shipping containers, including under or on top of other containers.
  • a craft substantially as described above wherein said craft is formed from a plurality of releasably secureable sections movable with respect to each other enabling the reversible configuration of the craft in an erected configuration for use as a water craft and a collapsed configuration for storage and/or transport.
  • shipment container refers to a substantially cuboid container dimensioned in accordance with any recognised national or international format or ISO standard for shipping containers.
  • said sections are pivotally and/or slidably attached to at least one adjacent section.
  • said sections are detachable from each other.
  • said craft is provided with standard shipping container lifting and attachment fittings.
  • the base section includes standard lifting and attachment fittings on an upper surface.
  • At lest some said lifting and/or attachment fittings are placed in locations on the craft such that in the collapsed configuration, the position of the fittings correspond to the positions of comparable fittings on standard shipping containers.
  • a craft substantially as described above wherein said sections includes a substantially rectangular base section with port and starboard longitudinal sides, said base section having a length and width corresponding to those of a shipping container, and a lower surface forming a bottom hull surface of the craft when configured in said erected configuration for aquatic use.
  • said craft also includes port and starboard centre sections, locatable alongside the respective port and starboard sides of the base section.
  • said craft further includes port and starboard bow sections and port and starboard stern sections, locatable fore and aft of the port and starboard centre sections respectively.
  • said port and starboard centre sections are both moveable between the said erected and said collapsed configurations by pivoting and/or sliding from a position laterally outboard from said centre section to a position on top of said base section respectively.
  • said port and starboard centre sections are pivotable through approximately 90° about said port and starboard longitudinal base sides, preferably in conjunction with the respective port and starboard bow and port and starboard stern sections.
  • said port and starboard centre sections are both moveable between the said erected and said collapsed configuration by detaching and relocating from a position laterally outboard from said centre section to a position on top of the ports and starboard sides of said base section respectively.
  • said port and starboard bow and port and starboard stern sections are moveable between the said erected and said collapsed configuration after the movement of the port and starboard centre sections on top of the base section by pivoting and/or sliding from positions fore and aft of the port and starboard centre sections respectively, to a position on top of said port and starboard centre section respectively.
  • said port and starboard bow and port and starboard stern sections are substantially pivotable through approximately 180° about lateral axes respectively located at the fore and aft ends of the port and starboard centre sections perpendicular to the longitudinal sides of the base section.
  • said port and starboard bow and port and seaboard stern sections are moveable between the said erected and said collapsed configuration by detaching and relocating from positions fore and aft of the port and starboard centre sections respectively, to a position on top of said port and starboard centre sections respectively.

  • the port and starboard bow and stern sections include standard rifling and attachment fittings on lower outer corners when in said erected configuration.
  • the craft may be collapsed into the strict dimension of a shipping container and yet retain the requisite strength to carry a fully loaded container when erected, a precise interrelation is required between the dimensions/proportions of the constituent sections forming the craft.
  • each section is releasably securable to at least one adjacent section in the collapsed and/or erected configurations to form a rigid structure.
  • the maximum length, width and height of the sections, as measured in the erected configuration are formed in accordance with one or more of the following criteria:
