ABSTRACT:
An explosive disconnect joins two portions of an underwater cable and an ctrical conductor extends from a squib to a remote detonator. The squib and conductor are cast inside a plug of epoxy or equivalent frangible material. Holes bored at opposite ends of the plug receive the two portions of the cable, for example, an anchor line and a buoy line. When the squib is detonated, the frangible plug disintegrates and an instrumentation package is buoyed to the surface for recovery. The nonmetallic explosive disconnect is waterproof, is corrosion resistent and is relatively inexpensive compared to other commercially available units.
