Order number 940406-171827-13 page 59 set 5 with 102 OFFICIAL-USE ONLY of: consisted of a 12 to 18-knot breeze and a short 3-ft chop from the northeast superimposed over @ 300-ft long, 6 to 8 ft high swell from the east southeast. Each mooring consisted of a 1500-1b anchor connected by a 5/32-in., 1 x 19 galvanized steel cable to a 36 to 4l-in. diameter buoy 150 ft below the surfacé. A floated 7/16-in. diameter nylon pennant 300 ft long connected this buoy to the surface instrumented buoy. Of the twenty moorings placed, 7 or 8 survived the effects of the event. One failed from collision with a vessel. Eleven failures resulted from undetermined effects of the detonation. The cause for ten of these was a tension break at the lower end of the cable; the cause for the eleventh could not be determined. The remaining mooring, which had no instrument buoy attached and was marked only by a spare subsurface buoy at the end of the nylon pennant, was never found. All but one cable failure was within 8000 801. KEYWORD(8S) 9003433 ft of surface zero. However, the survival of two moorings at 4800 £t from surface zero indicates that the wire size chosen, though marginal, would have been satisfactory for open sea conditions alone. For the combined sea and detonation conditions that did prevail, an increase to 1/4 in. diameter cable for stations within 8000 ft of surface zero probably would have been sufficient to maintain all moorings. 4 references.
