Ship construction

A method of building a superstructure on a ship, which superstructure accomodates a plurality of cabins and the local strength and the overall strength of which are at least equal to a minimum local strength and a minimum overall strength respectively, said method comprising,

• constructing a three-dimensional latticework over the uppermost deck covering the entire hull of the ship, the overall strength of the latticework being at least substantially equal to said minimum overall strength,
• installing a sandwich-construction deck plate in the latticework, the local strength of the deck plate being at least equal to said minimum local strength, and
• installing at least a lower and an upper tier of prefabricated cabins in the latticework, the prefabricated cabins being without floor structures and said uppermost deck forming a floor for the cabins of the lower tier and said deck plate forming a floor for the cabins of the upper tier.

A big passenger ship having a hull, a deck covering the entire hull of the ship, and a superstructure which extends above said deck and of which the local strength and the overall strength are at least equal to a minimum local strength and a minimum overall strength respectively, said superstructure comprising a threedimensional latticework of which the overall strength is at least substantially equal to said minimum overall strength, and at least an upper and a lower tier of cabins arranged one on top of the other in the latticework, each cabin of the upper tier having a floor structure which is supported by the latticework and of which the local strength is at least equal to said minimum local strength and each cabin being a prefabricated unit comprising walls and a ceiling structure and wherein each cabin unit includes a corridor section, the corridor sections of each tier of cabin units being in communication and forming a corridor.

A big passenger ship having a hull, a deck covering the entire hull of the ship, and a superstructure which extends above said deck and of which the local strength and the overall strength are at least equal to a minimum local strength and a minimum overall strength respectively, said superstructure comprising a three-dimensional latticework of vertical pillars that extend upwardly from said deck and horizontal supporting girders that are secured to the vertical pillars, the overall strength of the latticework being at least substantially equal to said minimum overall strength, and the ship also having at least an upper and a lower tier of cabins arranged one on top of the other in the latticework, each cabin of the upper tier having a floor structure which rests on the horizontal supporting girders and of which the local strength is at least equal to said minimum local strength, each cabin of the upper tier also having an outer bulkhead and the horizontal girders also supporting balconies or walkways outside said outer bulkheads.
