Book Description
The four tripod-type structures are designed, respectively, for the water depths (MLW) of 81 feet (one structure), 93 feet (one structure) and 105 feet (one structure), 93 feet (one structure) and 105 feet (two structures). The structures are to be anchored to the sea bed by driving 42-in diameter piling through each leg of the templets and penetrating approximately 250 feet into the subsea soils. Vulcan 560 hammer or equivalent will be employed to drive the piling into the desired penetration. The method employed to perform the computation of pipe pile capacity curves, as presented in Section 2, is empirical in nature. McClelland soil report (Volume No. 1, Foundation Investigation, Report to Cubic Corporation) serves as the basis of engineering data to develop the capacity curves for each boring site. Stress-wave equation analysis is used in Section 3 to produced pile driving resistance curves. It should be noted that these curves provide only a possible range of pile drivability for the engineer to have a better judgment in the design of piling foundations and in no way assume attainment of the desired penetration.

Book Description
The investigation reported herein concerns the structural configuration to be recommended for the four ocean structures for the East Coast Air Combat Maneuvering Range, offshore Kitty Hawk, North Carolina. In this investigation, three configurations are considered in some depth, those being the skirt-pile, the four-pile and the three-pile concepts. Configurations being considered to a lesser degree are those designated as the caisson and modified caisson. Of the five configurations mentioned, that employed as the developed previously under another contract. The primary area of endeavor relative to this investigation deals with the development (for one water depth of the four-pile and three-pile configurations to a stage comparable to that of the skirt-pile structure. No work was done, as a part of this investigation, on the skirt-pile concept or on either of the caissons. Rather, development calculations for these configurations were simply reproduced and included herein for reference.

Book Description
The proper subject of this report, is the development of the East Coast Air Combat Maneuvering Range, offshore Kitty Hawk, North Carolina. The portions of the development under consideration herein are the design, fabrication and installation of the four ocean structures which, with electronic gear, comprise and define the Range. Two objectives fundamental to the project, are the feasibility of completing the project within the summer of 1977 and the possibility of accomplishing the task within the funding available. The preliminary project plan, as reported herein, sets forth a suggested procedure and schedule by which those objectives can be fulfilled. Essentially, this plan considers the various aspects of design engineering, fabrication, transportation and installation for the three primary conceptual configurations considered in the Structural Concept Analysis Report, namely, the three-pile, the four-pile and the skirt-pile structures. The plans for each concept are presented in parallel as required by the ideosyncrasies of each concept.

Book Description
This report evaluates the fatigue limit strengths for the design of a tripod-type ocean structure for the East Coast Air combat Maneuvering Range Offshore Kitty Hawk, North Carolina. The ocean structure investigated herein, a three-pile structure with equilaterally spaced jacket legs, is installed in a water depth (MLW) of 105 feet. The structure is secured to the ocean floor permanently by driving tubular piles through the jacket legs into the seabed. A superstructure is attached to the piling above the jacekt. Contents: Elevations and Plans; Wave Forces on Structure; Fatigue Limit Stress; Fatigue Life of Structure; Modified Goodman Diagram for Design; Punching Shear Stress; Stress Analysis; and Wave forces.

Book Description
The purpose of this report is to provide a document insuring the structural integrity of two of the four marine structures of the U.S. Navy East Coast Air Combat Maneuvering Range, offshore of Kitty Hawk, North Carolina. These two structures are identified as Structure 3 at Site 3 and Structure 4 at Site 4, both resting in approximately 105 feet of water. Since the analysis of these two structures will differ only in the soil properties at each of their sites, the report will treat them as one except when the soil properties influence the anlaysis. Contents: Structural Drawings; Structural Idealization; Basic Loads; Loading Conditions; Space Frame Analysis; Tubular Joint Analysis; Pile-Jacket Connection; Pile Analysis; Installation Analyses; Corrosion Protection; and Material List and Weight.
