Abstract:

The purpose of this study was to make a sound determination on the feasibility of various structures for positioning a VORTAC at sea. The primary contractual restraints on the project were that the study should be applicable to a single facility located at Ocean Station Charlie latitude 52 degrees 45 minutes N, longitude 35 degrees 30 minutes W, that costs would be minimized, and that personnel safety would be paramount. The study extended to the broad categories of operating vessels and moored plat forms. The latter category was divided to include discussion of manned and unmanned craft, such as Liberty ships, submarines, seadromes and buoys. Of major concern in keeping the study within the imposed limits were the problem of deep-water anchoring in the North Atlantic and the reliability of present VORTAC electronic systems in a continuous, infrequently maintained application. Other troublesome problems were crew comfort, reprovisioning techniques in a continual heavy-sea environment, and the structural design of the antenna complex. Recommended methods of deep-water mooring and of heavy weather transfer operations have been discussed in detail, and suggested solutions outlined for each substantial difficulty encountered.
