Abstract
Abstract A hull of the bulk carrier type is strengthened for arctic service by beams extending along each side of the cargo carrying portion of the vessel approximately at the load water line. Struts extend transversely across the hull at spaced intervals to interconnect the beams and resist external ice pressures. The beams are also used as ducts to convey heated water for heating the hull in the vicinity of the water line. Some of this heated water can be discharged down the outside of the hull from a location somewhat above the load water line.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
124 words
A ship of the bulk carrier type having a cargo carrying portion and comprising a. a beam structure extending uninterruptedly along each side of said cargo carrying portion at approximately the load water line for strengthening the hull against external ice pressure thereagainst, and b. a plurality of strut assemblies extending transversely across the ship at longitudinally spaced intervals at the level of said beam structures for interconnecting said structures in a manner resistant to external ice pressure against the hull, c. wherein each said beam structure comprises a box beam defining a duct, d. the ship including means for generating heated water and for conveying said heated water along said duct for heating the hull in the vicinity of the load water line.
Claim 2
Dependent Claim
124 words
A ship of the bulk carrier type having a cargo carrying portion and comprising a. a beam structure extending uninterruptedly along each side of said cargo carrying portion at approximately the load water line for strengthening the hull against external ice pressure thereagainst, and b. a plurality of strut assemblies extending transversely across the ship at longitudinally spaced intervals at the level of said beam structures for interconnecting said structures in a manner resistant to external ice pressure against the hull, c. wherein each said beam structure comprises a box beam defining a duct, d. the ship including means for generating heated water and for conveying said heated water along said duct for heating the hull in the vicinity of the load water line.
Claim 3
Dependent Claim
51 words
A ship according to claim 1, e. including a bow portion forward of said cargo carrying portion, f. and means forming a continuation of said duct for conveying said heated water to said bow portion for heating the hull at said bow portion in the vicinity of said load water line.
Claim 4
Dependent Claim
31 words
A ship according to claim 1, including means connected to said duct for discharging heated water therefrom down the outside of the hull from a location above the load water line.
Claim 5
Dependent Claim
144 words
A ship of the bulk carrier type having a cargo carrying portion and comprising a. a beam structure extending uninterruptedly along each side of said cargo carrying portion at approximately the load water line for strengthening the hull against external ice pressure thereagainst, and b. a plurality of strut assemblies extending transversely across the ship at longitudinally spaced intervals at the level of said beam structures for interconnecting said structures in a manner resistant to external ice pressUre against the hull, c. wherein each said beam structure comprises a box beam defining two ducts, d. the ship including means for generating heated water and for conveying said heated water from said generating means in a first direction along one such duct and subsequently in the other direction along the other such duct for heating the hull in the vicinity of the load water line.
Claim 6
Dependent Claim
144 words
A ship of the bulk carrier type having a cargo carrying portion and comprising a. a beam structure extending uninterruptedly along each side of said cargo carrying portion at approximately the load water line for strengthening the hull against external ice pressure thereagainst, and b. a plurality of strut assemblies extending transversely across the ship at longitudinally spaced intervals at the level of said beam structures for interconnecting said structures in a manner resistant to external ice pressUre against the hull, c. wherein each said beam structure comprises a box beam defining two ducts, d. the ship including means for generating heated water and for conveying said heated water from said generating means in a first direction along one such duct and subsequently in the other direction along the other such duct for heating the hull in the vicinity of the load water line.
Claim 7
Dependent Claim
81 words
A ship including a. a hull, b. a mechanism for generating heated water, c. a duct extending along the sides of the hull in the vicinity of the load water line, d. means for conveying heated water from said mechanism along said duct for heating the hull in the vicinity of said load water line, and e. means connected to said duct for discharging heated water therefrom down the outside of the hull from a location above the load water line.
