Operations and Maintenance Manual for the East Coast Air Combat Maneuvering Range, Offshore Kitty Hawk, North Carolina. Revised.
Abstract
The sea based portion of the East Coast Air Combat Maneuvering Range is comprised of four structures located in the Atlantic Ocean offshore Kitty Hawk, North Carolina at the positions given in the 'as-built' drawings. The four ocean structures are of the same general configuration, triangular in planform but varying in overall height as dictated by the water depths at their respective locations. The structures are of welded steel construction and fabricated in units, each structure consisting of a superstructure, a jacket, piling and appurtenances. Ferrous material used in the fabrication of the structures is, in general, ordinary carbon steel, ASTM A36 or equivalent having a yield strength of 36 kips per square inch (ksi). The one significant exception is the material used in the construction of tubular members in the vicinity of the connection of intersecting members. The material used in these joint cans is normalized low-alloy steel, ASTM A633 Grade A or API Spec 2H (Fy = 42 ksi). The four superstructures are identical, each being comprised of two decks of beam/plate construction supported by tubular columns. The columns, laced together with Z-braces occurring immediately below the lower deck, extend from the upper deck to the top of the templet and are sufficiently long to place the lower deck well above the crest of the design storm wave. Access to the decks is provided by a stairway from the boat landing level to the upper deck.
