Abstract
A cargo ship for transporting wheeled vehicles and cargo units simultaneously has a hull with a bottom structure and a cargo space defined within the hull. The cargo space has at least first and second cargo sections. The first cargo section has a space grillage structure that is self-supporting and flexibly mounted to the hull of the ship so as to diminish the transmission of hull deformation loads to the space grillage structure. The second cargo section is located below the first cargo section and has cargo holds for containing heavy-weight cargo to provide ballast for the ship.
Claims39
A ship capable of transporting vehicles and other cargo units simultaneously, comprising:
- a load-bearing hull having a bottom structure and a side structure;
- a cargo space defined within the hull;
- a self-bearing cargo space grillage positioned in the cargo space, the cargo space grillage being substantially entirely supported by the hull bottom structure;
- and
- flexible mounting means for mounting said space grillage to the hull side structure and hull bottom to permit movement of said grillage relative to said hull side structure and hull bottom structure so as to diminish transmittal of hull side structure and hull bottom structure deflection to the cargo space grillage,
- the cargo space grillage having an upper channel structure defining ventilating upper channels in the grillage, a vertical channel structure defining ventilating vertical channels in the grillage;
- and a bottom channel structure defining ventilating lower channels in the grillage;
- whereby the upper channels, lower channels, and vertical channels permit effective ventilation of the cargo space grillage.

A cargo ship capable of transporting vehicles and other cargo units simultaneously, comprising:
- a hull having a bottom structure and opposite side structures that form a load-bearing shell with a side-to-side breadth dimension;
- a cargo space defined within the hull;
- a cargo handling opening defined in the hull permitting cargo to be moved in and out of the cargo space;
- a first cargo section defined within the cargo space, the first cargo section having a cargo space grillage that includes cargo cells, the cargo space grillage being self-supporting and mounted to the hull for movement relative thereto so as to diminish the transmission of hull deformation loads to the cargo space grillage, the first cargo section capable of receiving vehicles;
- and
- a second cargo section defined within the cargo space, the second cargo section comprising a cargo hold provided with guides, the second cargo section being located below the first cargo section, the second cargo section being capable of receiving relatively heavy platform-held and container-held cargo in order to provide ballast for the ship.
