Claims
- 1. The process of fabricating a marine operations structure having a central core and first and second ice walls circumferentially positioned about said central core for fracturing ice features, with said second ice wall above and contiguous with said first ice wall, wherein said first and second ice walls are constructed according to the process comprising the steps of:
- providing a sloping support base system comprising radial bulkheads and circumferentially-positioned web frame series integrally connecting ice wall plating to said bulkheads and web frames series;
- integrally affixing an exposed cross grid system of interlocking and reinforcing members to the exterior surfaces of said ice wall plating to form first and second ice wall preforms with said members projecting outward from said plating;
- installing a slip-form adjacent to said ice wall preforms and exteriorly of said plating;
- pouring cement/aggregate slurry onto said ice wall preforms between said plating and said slip-form to cover said cross grid of interlocking and reinforcing members;
- moving the slip-form upwards as the void spaces between the slip-form and the ice wall plating are filled with cement/aggregate slurry; and
- permitting the cement/aggregate slurry to harden to form an orthotropic composite steel/concrete ice wall with an exposed concrete surface.
- 2. The process of fabricating a marine operations structure according to claim 1, wherein said providing step includes the positioning of a base plate below the bulkheads and web frame series, and wherein said providing step includes the positioning of reinforcing girders and stiffeners adjacent to the radial bulkheads and the base plate.
- 3. The process of fabricating a marine operations structure according to claim 1, wherein the central core is formed in quadrants divided by fluid-tight bulkheads and wherein non-tight bulkheads are arranged in a cross grid pattern and extending vertically within the central core.
- 4. The process of fabricating a marine operations structure according to claim 3, wherein a central core is constructed with at least one moon pool is lined with a series of fluid-tight bulkheads.
- 5. The process of fabricating a marine operations structure according to claim 1, wherein at least two fluid-tight flats are positioned at spaced vertical positions to extend throughout the structure.
