Abstract
Apparatus for delivering a heavy cable such as a rescue cable from the oc's surface to an extended depth for attachment to an object such as a stranded submarine and, after attachment of the free end of the cable to the object, delivering the cable to the ocean's surface. A syntactic foam float provides positive buoyancy for a frame assembly which supports a cable reel holding the heavy cable. Releasable ballasts are included to provide an initial overall buoyancy of a small negative value during the descent of the appartus. A release system is provided to simultaneously release the releasable ballast to change the buoyancy of the apparatus to a positive value, release the cable reel to allow cable payout. The cable reel is coupled to a waterbrake system which limits the rate of cable payout to below the rate of ascent of the rescue cable reel. The waterbrake system includes a depth-activated clutch which engages a secondary waterbrake to slow the rate of cable payout near the ocean surface.
