Abstract
Abstract A ship of simplified construction is adapted for the marine transportation of cryogenic material. At least one single barrier containment tank is located within the hull of the ship. On the inboard side of the inner hull and transverse bulkheads of the ship is provided a thermal insulating system, and covering the inner surface of this insulating system is a gas and liquid impervious liner. A space is provided between the liner and the wall of each containment tank and a cofferdam is provided outboard of the inner hull, outboard of the inner bottom and between the transverse bulkheads. Two circulation systems are provided, the first being provided in the space intermediate the liner and the tank, and the second being provided in the space defined by the cofferdam. Means for the detection of leaks in the containment system are also provided.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
173 words
A ship for the transportation of cryogenic materials and comprising: an outer hull; an inner hull; an outer bottom; and an inner bottom; transverse bulkheads dividing the interior of said inner hull into a plurality of cargo holds; a single barrier containment tank positioned within each said cargo hold in spaced relation to the boundaries thereof; an insulation system carried on the cargo hold boundaries substantially surrounding the containment tank positioned therein; a non-structural liquid and gas impervious liner, serving as a secondary barrier, carried by said insulation system substantially surrounding the containment tank and defining therewith a barrier space; and a cofferdam system outboard of and surrounding said inner hull and said inner bottom and positioned between adjacent tanks, the portion of said cofferdam system associated with the inner hull and the inner bottom serving as a double barrier preventing the passage of sea water and ballast liquid into the insulation system, and the portion of the cofferdam system positioned between adjacent tanks serving to enable heat transfer to said transverse bulkheads.
Claim 2
Dependent Claim
173 words
A ship for the transportation of cryogenic materials and comprising: an outer hull; an inner hull; an outer bottom; and an inner bottom; transverse bulkheads dividing the interior of said inner hull into a plurality of cargo holds; a single barrier containment tank positioned within each said cargo hold in spaced relation to the boundaries thereof; an insulation system carried on the cargo hold boundaries substantially surrounding the containment tank positioned therein; a non-structural liquid and gas impervious liner, serving as a secondary barrier, carried by said insulation system substantially surrounding the containment tank and defining therewith a barrier space; and a cofferdam system outboard of and surrounding said inner hull and said inner bottom and positioned between adjacent tanks, the portion of said cofferdam system associated with the inner hull and the inner bottom serving as a double barrier preventing the passage of sea water and ballast liquid into the insulation system, and the portion of the cofferdam system positioned between adjacent tanks serving to enable heat transfer to said transverse bulkheads.
Claim 3
Dependent Claim
19 words
The ship as set forth in claim 1, further comprising means for circulating a gas within said cofferdam system.
Claim 4
Dependent Claim
20 words
The ship as set forth in claim 1, further comprising circulation means for circulating a gas in said barrier space.
Claim 5
Dependent Claim
25 words
The ship as set forth in claim 2, further comprising said cofferdam system providing for circulation of gas around alternate tanks in a horizontal sense.
Claim 6
Dependent Claim
22 words
The ship as set forth in claim 1, further comprising leak detection means for detecting presence of cargo in said barrier space.
Claim 7
Dependent Claim
24 words
The ship as set forth in claim 1, further comprising leak detection means for detecting presence of cargo and/or water in said cofferdam system.
Claim 8
Dependent Claim
141 words
A ship for transporting cryogenic materials comprising: an outer hull; an inner hull; an outer bottom; an inner bottom; a deck structure; a plurality of transverse bulkheads forming a plurality of holds within the inner hull of the ship; a plurality of single wall containment tanks, each positioned within a respective hold; and insulating system substantially surrounding each of said containment tanks; a non-structural gas and liquid impervious liner substantially surrounding each of said containment tanks and positioned on said insulating system; a barrier space intermediate said liner and said containment tank, and substantially surrounding said containment tank; and a cofferdam system surrounding and isolating said insulation systems from sea water and ballast liquid and comprising in part longitudinal walls positioned outboard of said inner hull, bottom walls positioned outboard of said inner bottom and transverse walls adjacent said transverse bulkheads.
Claim 9
Dependent Claim
141 words
A ship for transporting cryogenic materials comprising: an outer hull; an inner hull; an outer bottom; an inner bottom; a deck structure; a plurality of transverse bulkheads forming a plurality of holds within the inner hull of the ship; a plurality of single wall containment tanks, each positioned within a respective hold; and insulating system substantially surrounding each of said containment tanks; a non-structural gas and liquid impervious liner substantially surrounding each of said containment tanks and positioned on said insulating system; a barrier space intermediate said liner and said containment tank, and substantially surrounding said containment tank; and a cofferdam system surrounding and isolating said insulation systems from sea water and ballast liquid and comprising in part longitudinal walls positioned outboard of said inner hull, bottom walls positioned outboard of said inner bottom and transverse walls adjacent said transverse bulkheads.
Claim 10
Dependent Claim
34 words
The ship as recited in claim 7, further comprising: first circulation means for circulating a gas through said cofferdam system; and second circulation means for circulating a gas through each of said barrier spaces.
Claim 11
Dependent Claim
35 words
The ship as recited in claim 7, wherein the insulation system associated with each tank is positioned on said inner hull, said inner bottom, said deck and one of said transverse bulkheads and transverse walls.
Claim 12
Dependent Claim
20 words
The ship as recited in claim 7 and further comprising means for detecting presence of cargo in said barrier space.
Claim 13
Dependent Claim
21 words
