Abstract
Barge double hull sections wherein at least part of the double hull is comprised of first and second layers and an intermediate layer of elastomer material bonded to the first and second layers. By manufacturing double hull walls of such three layered structures, the stiffness of the hull as compared to hulls of the prior art can be significantly increased, thereby decreasing the amount of separate stiffeners required in the hull structure.
Claims26
A hull section with an outer hull and an inner hold comprising:
- inner hull plating comprising an inner bottom defining a bottom of said hold and a lower inner side shell defining lower sides of said hold;
- outer hull plating comprising an outer bottom defining a bottom of said outer hull and a lower outer side shell defining lower sides of said outer hull;
- and
- a plurality of transverse girders located, in a spaced apart relationship, transversely between the inner and outer bottoms, each of said plurality of transverse girders having two associated web frames located at each end of said transverse girders and between said lower side shells;
- wherein said inner hull plating and said outer hull plating are each comprised of a first metal layer and a second layer and an intermediate layer of elastomer bonded to said first and second layers so as to transfer shear forces therebetween.

A hull section with an outer hull and an inner hold;
- comprising:
- a bottom defining on a first side at least a part of the bottom of said outer hull and, on a second side, the bottom of said inner hold;
- inner side shells defining side walls of said inner hold;
- bottom outer side shells defining side walls of said outer hull and parts of the bottom of the outer hull not defined by said bottom hull wall;
- wherein
- said bottom is comprised of a first layer, a second layer and an intermediate layer of elastomer bonded to said first and second layers so as to transfer shear forces therebetween.
