Claim 6

The structure as in claim 1, wherein a plurality of said decks are provided with assembly openings constituting said foundation seatings, at least some of said openings having longitudinal dimensions substantially corresponding to an integral multiple of said second grid spacing between consecutive of said lateral grid lines.

Claim 7

The structure as in claim 5, wherein said at least one deck which has foundation seatings, also includes a plurality of additional load bearing support elements in the form of beams arranged at selected ones of said longitudinal and lateral grid lines.

Claim 8

The structure as in claim 6, wherein at relatively more heavily stressed areas of said at least one deck, said load bearing beams are arranged at consecutive ones of longitudinal and lateral grid lines.

Claim 9

The structure as in claim 6, wherein at least some of said assembly openings are slightly smaller than a periphery defined by the longitudinal and lateral grid lines which are closest to the periphery of a corresponding opening.

Claim 10

The structure as in claim 1, wherein at least one of said access openings is at least as high as it is wide.

Claim 11

The structure as in claim 9, wherein the width of said at least one access opening is 5 to 15% larger than said second spacing between successive lateral grid lines.

Claim 12

The structure as in claim 10, wherein said height and width are about 10% larger than the spacing of the lateral grid lines.

Claim 13

The structure as in claim 10, wherein said at least one opening has a height which is substantially an integral multiple of the width of said at least one access opening.

Claim 14

The structure as in claim 1, including at least one fabricated room disposed vertically and supported by at least one deck, wherein the room includes vertical walls which align with selected ones of said longitudinal and lateral grid lines.

Claim 15

A maritime structure comprising a vessel with several vertically spaced decks having mountings for receiving certain devices comprising fixtures and apparatus, said mountings being formed selectively from longitudinal support elements which include longitudinal beams, longitudinal strips, deck girders, longitudinal walls and longitudinal bulkheads, as well as selected ones of lateral support elements which include cross beams, cross frames, frame girders, spars, lateral walls and lateral bulkheads which are arranged in parallel and at intervals, wherein between some of the support elements of superjacent decks are arranged one or more of load bearing longitudinal walls and bulkheads, which are disposed to function as vertical support members, and of which at least one is equipped with access openings, wherein said longitudinal support elements and said lateral support elements are arranged along uniformly spaced longitudinal and lateral grid lines of a unit grid incorporated into a basic plan of the vessel, wherein at least said fixtures and apparatus are incorporated into said unit grid and wherein substantially square access openings are incorporated into the grid, wherein at least some of said access openings are made slightly larger in height and width than the grid unit; said structure including assembly openings adapted to receive said fixtures and apparatus, said structure including webs which substantially form inside edges of said openings, said webs coinciding with selected grid lines, and including bearing-surfaces for certain mounting-flanges of said fixtures and apparatus, wherein said bearing surfaces project outwardly beyond said selected grid lines, and wherein said assembly openings include edges which are offset to the inside of selected ones of said grid lines in order to accommodate a flange for mounting an assembly cover on said assembly opening.

Claim 16

A maritime structure comprising a vessel with several vertically spaced decks having mountings for receiving certain devices comprising fixtures and apparatus, said mountings being formed selectively from longitudinal support elements which include longitudinal beams, longitudinal strips, deck girders, longitudinal walls and longitudinal bulkheads, as well as selected ones of lateral support elements which include cross beams, cross frames, frame girders, spars, lateral walls and lateral bulkheads which are arranged in parallel and at intervals, wherein between some of the support elements of superjacent decks are arranged one or more of load bearing longitudinal walls and bulkheads, which are disposed to function as vertical support members, and of which at least one is equipped with access openings, wherein said longitudinal support elements and said lateral support elements are arranged along uniformly spaced longitudinal and lateral grid lines of a unit grid incorporated into a basic plan of the vessel, wherein at least said fixtures and apparatus are incorporated into said unit grid and wherein substantially square access openings are incorporated into the grid, wherein at least some of said access openings are made slightly larger in height and width than the grid unit; said structure including assembly openings adapted to receive said fixtures and apparatus, said structure including webs which substantially form inside edges of said openings, said webs coinciding with selected grid lines, and including bearing-surfaces for certain mounting-flanges of said fixtures and apparatus, wherein said bearing surfaces project outwardly beyond said selected grid lines, and wherein said assembly openings include edges which are offset to the inside of selected ones of said grid lines in order to accommodate a flange for mounting an assembly cover on said assembly opening.

Claim 17
