Abstract
Abstract Methods and apparatus for offshore operations including individually significant aspects comprising: 1. Methods and apparatus for providing lateral force transmitting arch means extending across a vessel passageway which is laterally bounded by upwardly projecting portions of a substructure and bounded on the top by an integrated deck: 2. Methods and apparatus for assemblying an integrated deck with a substructure wherein there are effected horizontal and vertical shock absorbing action, motion dampening, and desired alignment; and 3. Methods and apparatus for assemblying an integrated deck with a substructure wherein, at a relatively slower rate, an integrated deck is lowered into engagement with a substructure and, at a subsequent more rapid rate, a vessel initially supporting the integrated deck is vertically separated therefrom.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
232 words
A method of erecting an offshore structure comprising: transportable substructure means connected with a submerged surface and including a slotted upper end defining a vessel passageway; said method being characterized by: providing integrated deck means operable to be supported on vessel means for transportation to the vicinity of said substructure means, with said vessel means moving into said passageway so as to position said integrated deck means generally above said substructure means and in alignment therewith; causing said vessel means to lower said integrated deck means onto the top of said substructure means and form said offshore structure; and providing in said offshore structure, comprising said interconnected substructure means and integrated deck means, with lateral force transmitting means carried by one of said substructure means and said integrated deck means, defining lateral force transmitting, arch-like means extending transversely from opposite sides of said vessel passageway, generally across at least side portions of said vessel passageway to an intermediate portion of one of said jacket means and integrated deck means, and at least partially extending across said vessel means while said integrated deck means is supported thereon and said vessel means is in said passageway; said lateral force transmitting means extending laterally beyond side portions of said vessel means, with outer portions thereof being disengaged therefrom when said integrated deck means is supported thereon, and said vessel means is disposed in said passageway.
Claim 2
Independent Claim
232 words
A method of erecting an offshore structure comprising: transportable substructure means connected with a submerged surface and including a slotted upper end defining a vessel passageway; said method being characterized by: providing integrated deck means operable to be supported on vessel means for transportation to the vicinity of said substructure means, with said vessel means moving into said passageway so as to position said integrated deck means generally above said substructure means and in alignment therewith; causing said vessel means to lower said integrated deck means onto the top of said substructure means and form said offshore structure; and providing in said offshore structure, comprising said interconnected substructure means and integrated deck means, with lateral force transmitting means carried by one of said substructure means and said integrated deck means, defining lateral force transmitting, arch-like means extending transversely from opposite sides of said vessel passageway, generally across at least side portions of said vessel passageway to an intermediate portion of one of said jacket means and integrated deck means, and at least partially extending across said vessel means while said integrated deck means is supported thereon and said vessel means is in said passageway; said lateral force transmitting means extending laterally beyond side portions of said vessel means, with outer portions thereof being disengaged therefrom when said integrated deck means is supported thereon, and said vessel means is disposed in said passageway.
Claim 3
Dependent Claim
241 words
Apparatus operable to be used in cooperation with: transportable substructure means, connected with a submerged surface and including a slotted upper end defining a vessel passageway; said apparatus being characterized by: integrated deck means operable to be supported on vessel means for transportation to the vicinity of said substructure means, with said vessel means moving into said passageway so as to position said integrated deck means generally above said substructure means and in alignment therewith; said vessel means being operable to cause said integrated deck means to lower onto the top of said substructure means and form said offshore structure; and said integrated deck means, being operable when interconnected with said substructure means, to define said offshore structure, with said offshore structure including lateral force transmitting means carried by one of said substructure means and said integrated deck means, defining lateral force transmitting, arch-like means extending transversely from opposite sides of said vessel passageway, generally across at least side portions of said vessel passageway to an intermediate portion of one of said substructure means and integrated deck means, and at least partially extending across said vessel means while said integrated deck means is supported thereon and said vessel means is in said passageway; said lateral force transmitting means extending laterally beyond side portions of said vessel means, with outer portions thereof being disengaged therefrom when said integrated deck means is supported thereon, and said vessel means is disposed in said passageway.
Claim 4
Dependent Claim
241 words
Apparatus operable to be used in cooperation with: transportable substructure means, connected with a submerged surface and including a slotted upper end defining a vessel passageway; said apparatus being characterized by: integrated deck means operable to be supported on vessel means for transportation to the vicinity of said substructure means, with said vessel means moving into said passageway so as to position said integrated deck means generally above said substructure means and in alignment therewith; said vessel means being operable to cause said integrated deck means to lower onto the top of said substructure means and form said offshore structure; and said integrated deck means, being operable when interconnected with said substructure means, to define said offshore structure, with said offshore structure including lateral force transmitting means carried by one of said substructure means and said integrated deck means, defining lateral force transmitting, arch-like means extending transversely from opposite sides of said vessel passageway, generally across at least side portions of said vessel passageway to an intermediate portion of one of said substructure means and integrated deck means, and at least partially extending across said vessel means while said integrated deck means is supported thereon and said vessel means is in said passageway; said lateral force transmitting means extending laterally beyond side portions of said vessel means, with outer portions thereof being disengaged therefrom when said integrated deck means is supported thereon, and said vessel means is disposed in said passageway.
Claim 5
Dependent Claim
46 words
An offshore structure as described in claim 2 wherein: said lateral force transmitting means comprises a generally downwardly concave, arch-like means formed on the under side of said integrated deck means and operable to provide lateral force transmission within said offshore structure, across said vessel passageway.
Claim 6
Dependent Claim
45 words
An offshore structure as described in claim 2 wherein: said lateral force transmitting means comprises a generally upwardly concave, arch-like means formed on the under side of said vessel passageway and operable to provide lateral force transmission within said offshore structure across said vessel passageway.
Claim 7
Dependent Claim
77 words
An offshore structure as described in claim 2 wherein: said lateral force transmitting means comprises a generally downwardly concave, arch-like means formed on the under side of said integrated deck means; and a generally upwardly concave, arch-like means formed on the under side of said vessel passageway; said generally downwardly and upwardly concave, arch-like means cooperating to define horizontal force transmitting means extending across the top and base of at least side portions of said vessel passageway.
