The techniques used in the construction of automatic marine beacons with the use of a helicopter; the construction of an 8 mi 11 kv overhead line by helicopter; the development of a fixed-wind generator; and the laying of a 3 1/2 mi 11 kv submarine cable in one length are described. The structure had a low center of gravity so that it hung vertically below the helicopter and had no tendency to fall over when positioned. The reinforced concrete slab foundation is 6 ft square and 2 ft thick. A fixed-wind charger was developed to enable batteries to be charged on site at marine beacons where there is no power supply.
