Abstract
The present disclosure relates to a method and apparatus for recovering sunken wrecks. More particularly, the present invention concerns a method and apparatus for recovering sunken wrecks wherein a harpoon is launched from a submarine device, implants itself in the wreck and is provided with a rope and means for fastening a pull cable. The end of the rope which is remote from the harpoon is floated to the surface. An apparatus placed at the end of the pull cable is caused to descend along the rope, and at the end of the stroke the apparatus automatically fastens itself to the harpoon. Thereupon, the wreck is pulled up by means of the pull cable.
