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.
