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 assembling 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: 5
Claim 1
Independent Claim
113 words
A method of forming an offshore structure comprising: providing substructure means, connected with a submerged surface; supporting an integrated deck means on vessel means; moving said vessel means so as to position said integrated deck means over said substructure means; lowering said integrated deck means at a first, relatively slower transfer rate so as to transfer the load of said integrated deck means from said vessel means to said substructure means; and thereafter separating previously engaged portions of said vessel means and said integrated deck means at a second, relatively more rapid rate, thereby reducing tendencies for wave action-induced forces and movements to cause damage to said integrated deck means and vessel means.
Claim 2
Independent Claim
113 words
A method of forming an offshore structure comprising: providing substructure means, connected with a submerged surface; supporting an integrated deck means on vessel means; moving said vessel means so as to position said integrated deck means over said substructure means; lowering said integrated deck means at a first, relatively slower transfer rate so as to transfer the load of said integrated deck means from said vessel means to said substructure means; and thereafter separating previously engaged portions of said vessel means and said integrated deck means at a second, relatively more rapid rate, thereby reducing tendencies for wave action-induced forces and movements to cause damage to said integrated deck means and vessel means.
Claim 3
Dependent Claim
129 words
Apparatus for forming an offshore structure comprising: substructure means, connected with a submerged surface; integrated deck means; vessel means; means supporting said integrated deck means on said vessel means; means operable to move said vessel means so as to position said integrated deck means over said substructure means; first transfer means for lowering said integrated deck means at a first, relatively slower transfer rate so as to transfer the load of said integrated deck means from said vessel means to said substructure means; and second, separation means for thereafter separating previously engaged portions of said vessel means and said integrated deck means at a second, relatively more rapid rate, thereby reducing tendencies for wave action-induced forces and movements to cause damage to said integrated deck means and vessel means.
Claim 4
Dependent Claim
129 words
Apparatus for forming an offshore structure comprising: substructure means, connected with a submerged surface; integrated deck means; vessel means; means supporting said integrated deck means on said vessel means; means operable to move said vessel means so as to position said integrated deck means over said substructure means; first transfer means for lowering said integrated deck means at a first, relatively slower transfer rate so as to transfer the load of said integrated deck means from said vessel means to said substructure means; and second, separation means for thereafter separating previously engaged portions of said vessel means and said integrated deck means at a second, relatively more rapid rate, thereby reducing tendencies for wave action-induced forces and movements to cause damage to said integrated deck means and vessel means.
Claim 5
Dependent Claim
54 words
The apparatus of claim 2 wherein said second, separation means includes: rocker means, carried by said vessel means and detachably supporting said integrated deck means for yieldably impeded, wave action accommodating movement relative to said vessel means; and support means for said rocker means operable to effect rapid lowering thereof on said vessel means.
