  • Patent number: 4674430
    Abstract: A transverseless ship has at least its side portions and bottom portion comprised of a double hull construction which comprises an inner hull plating and an outer hull plating connected together only by transverse bulkheads and a plurality of connecting longitudinal members fixed to the bulkheads. The bottom portion of the ship has a space defined by at least two optionally selected connecting longitudinal members and divided by a partition into an upper chamber and a lower chamber. The upper chamber is adapted in its entirety to pass a fluid therethrough. With this structure, external forces acting on the ship are delivered from the connecting longitudinal members to the transverse bulkheads to prevent the inner and outer platings from buckling. The absence of reinforcing transverse members intersecting the connecting longitudinal members assures automatic welding operation with greatly improved efficiency.

  • Patent number: 4573422
    Abstract: A transverseless ship has at least its side portions and bottom portion comprised of a double hull construction which comprises an inner hull plating and an outer hull plating connected together only by transverse bulkheads and a plurality of longitudinal connecting member fixed to the bulkheads. The bottom portion of the ship has a space defined by at least two optionally selected connecting longitudinal members and divided by two horizontal partitions into two upper chambers and a lower chamber. The upper chambers are adapted to pass different fluids therethrough, and the lower chamber is provided with docking brackets each conforming to the sectional shape thereof. With this structure, external forces acting on the ship are delivered from the connecting longitudinal members to the transverse bulkheads to prevent the inner and outer platings from buckling.
